Survey on the Acquisition of Chinese Vocabulary by International Students—A Case Study of Southwest Petroleum University

Vocabulary is the basic unit that constitutes a language, and is an important carrier for conveying information and constructing meaning. The study of Chinese vocabulary acquisition in China is mostly on the analysis of bias. The study adopts questionnaire survey method which take foreign students from Southwest Petroleum University as an example to study the vocabulary acquisition of the Chinese everyday language. The phenomenon of investigation was analyzed from Atkinson’s social cognitive perspective. The results of the study indicate that vocabulary of everyday terms has not been fully learned by international students even they got certificates. And everyday language vocabulary should receive attention from teachers to international students. In teaching process, it’s vital to give full play to the alignment between the social environment, social activities and learners, which could help international students improve their language competence.

Properties of proto neutron star PSR J0737-3039A* *Supported by the Natural Science Foundation of China (11447003) and the Special Project of Science and Technology Strategic Cooperation between Nanchong City and Southwest Petroleum University (SXHZ017)

Using five sets of nucleon coupling constants (DD-MEI, GL85, GL97, GM1, and NL2), we find that the radius of the PNS PSR J0737-3039A is R=15.693–18.846 km, the central baryon density is =0.247–0.359 fm, the central energy density is =4.3010– 6.4910 , and the central pressure is =3.7910 – 5.8510 . With DD-MEI, GL85, GL97, and GM1, baryon octets appear in the PNS PSR J0737-3039A. With NL2, only the baryons n, p, Λ, , , , and are present. Corresponding to the same baryon density, the relative densities of the same baryon in the PNS PSR J0737-3039A calculated using different nucleon coupling constants differ greatly. The central relative baryon densities of the PNS PSR J0737-3039A calculated using different nucleon coupling constants also differ greatly.

AWWA Water Science Author Spotlight

Having recently published an article in AWWA Water Science, Hongfang Lu answered questions from the publication's editor-in-chief, Kenneth L. Mercer, about the research. A Hybrid Model for Monthly Water Demand Prediction: A Case Study of Austin, Texas Hongfang Lu, John Matthews, and Shuai Han I am now an associate professor at Southeast University in China. My current research focuses on trenchless technology and buried pipeline health monitoring. My research has been going on for nearly a decade, and my projects are all about pipelines. Since I have a background in oil and gas engineering, my initial research was on oil and gas pipelines. During my PhD program, I also did some research on water pipelines. During my PhD program, I was involved in a Water Research Foundation project on water pipeline condition assessment. During that time, I did some research on water. In addition, trenchless technology is more widely used in the water field. During his summer vacation in 2018, Hongfang went to New York City with one of his teachers and her family. So far, three teachers have greatly influenced my career. In chronological order, the first one is Professor Xiaonan Wu from Southwest Petroleum University (Chengdu, China), who was my tutor at the master's degree stage. She told me to have the courage to challenge complex problems in research. The second is my PhD research advisor, Dr. Tom Iseley, a professor at Purdue University (West Lafayette, Ind.) and a leader in the trenchless industry. He told me to keep an open mind in research and be mindful of the intersections between disciplines. The third is my current team leader, Professor Zhao-Dong Xu from Southeast University. He often reminds us to combine theory with practice and do research that is meaningful to people. This research is related to water demand prediction using machine learning methods. The motivation is to establish a hydraulic calculation model of the water supply network through the prediction of water demand. Many buried pipelines worldwide are aging or about to enter the aging stage. Health monitoring and trenchless repair of pipelines are essential; therefore, my research direction is related to these two points. Personally, I am very interested in the structure of pipes. Although pipeline structure is relatively simple compared with other forms, it also involves many scientific problems. The outbreak of COVID-19 in 2019 has triggered a lot of thinking among scholars. But even before the onset of its public health problems, using limited samples to predict future conditions and then using those results to take public measures was an important challenge in research. In June 2021, Hongfang participated in the biennial badminton competition at Southeast University, Nanjing, China. I was born in Nanyang, Henan Province, China, a place with abundant oil resources at that time. So I have been relatively familiar with oil since I was a child. When I was in college, my major was oil and gas storage and transportation engineering. In studying, I was very interested in pipelines, the vehicle for oil and gas resource transportation.

Global Research Trends on Shale Gas from 2010–2020 Using a Bibliometric Approach

In the last few decades, shale gas resources have attracted much global attention as potential sources for clean and affordable energy. Due to this fact, coupled with the increasing energy shortfall, shale gas has become an increasingly attractive energy prospect from both an environmental and economic perspective. This development has led to the rapid growth in the number of researchers and publications in the field of shale gas. Although there are few review articles on the state of research on shale gas, the literature lacked a bibliometric analysis. This study is intended to fill the research gap by carrying out a bibliometric analysis of 9247 shale gas articles that were published between 2010 and 2020. The Web of Science database was used to collect the data. The analysis was performed to identify the most productive authors, institutions, countries, and sources, and to visualize existing collaborations as well as provide valuable information which could form the basis for establishing future collaboration. The analysis results revealed that Li J has the highest number of publications on shale gas whereas Loucks RG is the most cited author. The top three countries with the highest number of publications in shale gas research are China, USA, and Canada, while the China University of Petroleum (Beijing), China University of Geosciences, and Southwest Petroleum University China were the three top institutions with the highest number of publications. Fuel, International Journal of Coal Geology, and Marine and Petroleum Geology are the journals with the highest number of published articles on shale gas. The keyword analysis indicated that shale gas, hydraulic fracturing, pore structure, permeability, adsorption, kinetics, pyrolysis, organic matter, thermal maturity, and numerical simulation are the predominant research topics. This showed the multi-dimensional and multi-faceted character of the shale gas field. Besides, it appeared to be an exciting topic for further study that is based on a detailed evaluation of the shale gas literature. In fact, shale gas, hydraulic fracturing (fracking), CO2 sequestration, kinetic, gas adsorption, diffusion, and simulation are becoming emerging research hotspots. The bibliometric analysis that was presented in this study has revealed valuable information about the most active institutions and countries, and the most influential authors in the field of shale gas which could form the basis for establishing future collaboration. Furthermore, it can help researchers to understand the global research trend in shale gas as well as provide references for establishing future research directions.

Study Evaluates Fracturing Interference for Multiwell Pads in Shale Gas Reservoirs

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 201694, “Interwell Fracturing Interference Evaluation of Multiwell Pads in Shale Gas Reservoirs: A Case Study in WY Basin,” by Youwei He, SPE, Jianchun Guo, SPE, and Yong Tang, Southwest Petroleum University, et al., prepared for the 2020 SPE Annual Technical Conference and Exhibition, originally scheduled to be held in Denver, Colorado, 5–7 October. The paper has not been peer reviewed. The paper aims to determine the mechanisms of fracturing interference for multiwell pads in shale gas reservoirs and evaluate the effect of interwell fracturing interference on production. Field data of 56 shale gas wells in the WY Basin are applied to calculate the ratio of affected wells to newly fractured wells and understand its influence on gas production. The main controlling factors of fracturing interference are determined, and the interwell fracturing interacting types are presented. Production recovery potential for affected wells is analyzed, and suggestions for mitigating fracturing interference are proposed. Interwell Fracturing Interference Evaluation The WY shale play is in the southwest region of the Sichuan Basin, where shale gas reserves in the Wufeng-Longmaxi formation are estimated to be the highest in China. The reservoir has produced hydrocarbons since 2016. Infill well drilling and massive hydraulic fracturing operations have been applied in the basin. Each well pad usually is composed of six to eight multifractured horizontal wells (MFHWs). Well spacing within one pad, or the distance between adjacent well pads, is so small that fracture interference can occur easily between infill wells and parent wells. Fig. 1 shows the number of wells affected by in-fill well fracturing from 2016 to 2019 in the basin. As the number of newly drilled wells increased between 2017 and 2019, the number of wells affected by hydraulic fracturing has greatly increased. The number of wells experiencing fracturing interaction has reached 65 in the last 4 years at the time of writing.

Evaluation of Experimental Setup and Procedure for Rapid Preparation of Natural Gas Hydrate

The natural gas hydrate (NGH) reservoir in China is mainly distributed in the continental shelf with water depths ranging from 600–1500 m, about 90% of which is stored in the shallow area of the deep sea, with weak cementation and non-diagenetic characteristics. In order to test and study this type of NGH, samples must be prepared in situ, in large quantities, and at fast speed. At present, there are problems with the common stirring, spraying, and bubbling preparation techniques available, such as slow generation rate, low gas storage density, and lack of rapid preparation. Therefore, the rapid preparation of large samples of non-diagenetic natural gas hydrate has received extensive attention at home and abroad. In view of this technical bottleneck, Southwest Petroleum University innovatively established a rapid preparation kettle of 1062 L. In this paper, the preparation experiment of natural gas hydrate in the South China Sea (the pressure of the preparation kettle was reduced from 7 MPa to 3.3 MPa) was carried out in the preparation method of the ‘three-in-one’ (stirring method, spraying method, bubbling method) and experimental test method. In the process of preparation of non-diagenetic gas hydrate, the data of dynamic image, temperature, pressure, electrical resistivity, and reaction time are tested. During the preparation of natural gas hydrate, temperature, pressure, and electrical resistivity curves in four preparation methods were made, respectively. Through the experimental data analysis of different preparation methods of natural gas hydrate, it has been found that the preparation time of natural gas hydrate using the stirring method, the spraying method, and the bubbling method alone require a longer preparation time. However, when the three-in-one method is used to prepare natural gas hydrate, the preparation cycle of natural gas hydrate is obviously shortened. The preparation time of the single method of stirring method, spraying method, and bubbling method is respectively about 5.13, 3.59, and 3.37 times as long as that of three-in-one method. The three-in-one method for preparing natural gas hydrate greatly improves the preparation efficiency, which has a great significance to the scientific and technological progress of experimental research and evaluation methods of natural gas hydrate.
