Ортогональные ветроэнергоустановки для нефтегазопромысловых объектов на суше и на море

Wind and solar power plants for autonomous power supply of small oil and gas facilities with a capacity of no more than 20 kW, wind power plants in their composition – 10 kW with a power factor (energy efficiency) of no more than 0.35–0.45 are considered. An improved design of an orbital wind power plant based on a combined H-Darye-Savonius rotor has been developed. Experiments on the laboratory installation showed that the maximum values of the power factor reached 0.60, which is much higher than that of the rotors of known types of wind turbines. The values of the CRDS power factor are calculated for various geometric dimensions of the N-Darye and Savonius rotors included in its composition. With an increase in wind speed to the nominal value of 9.0 m/s for small and medium power wind turbines and a rotor diameter of 15.0 m, the combined rotor power reaches almost 60 kW. The proposed orthogonal wind power plants with a nominal capacity of up to 60 kW will be able to be used together with other power plants for autonomous power supply at oil and gas field facilities on land and at sea, and in the future at intelligent fields.

Relevance To cool the gas to the required temperature values in gas production and transportation in Russia, the most widespread has been implemented in the device of air-cooled gas. The installed capacity of electric drives of fans of gas air cooling devices reaches 70 % of the total installed capacity of gas field facilities. Therefore, the issue of increasing the energy efficiency of electrical complex of gas air cooling device by introducing a frequencycontrolled electric drive is relevant. Aim of research To develop a method of frequency control and to investigate the technological features of the operation of gas air cooling devices with a two-stage cooling scheme that ensures minimal electricity consumption. Research methods Mathematical methods of calculation and analysis, Mathcad software package. Results Based on the developed optimization algorithm for selecting the rotational speeds of the motors of the section of the gas air cooling apparatus, it is shown that the most effective increase in thermal efficiency can be used with separate frequency control of the fans of the section of each stage. For separate frequency control, the objective function of optimal control of the frequency-controlled electric drive of the gas air cooling apparatus according to the criterion of minimum power consumption has been developed.

Геофизические исследования в рамках инженерных изысканий на шельфе Охотского моря

The paper deals with the results of marine engineering surveys on the shelf of the Okhotsk Sea. According to the results of the study, potentially hazardous geological and technogenic objects were localized, and a network of buried river paleo–incisions was identified. The work performed allowed us to obtain materials that ensure the safe installation of floating drilling rigs for the period of well drilling, design and construction of oil and gas field facilities.

An analysis of the dynamic interaction between ice floes with the marine and offshore oil and gas field facilities, which are the basis of the conditions of occurrence and development of self-oscillation using a one-dimensional mathematical model of oscillations facilities. Determined by dynamic ice loads on structures and analyzed the conditions for establishing self-oscillations along with the definition of their parameters. Offers recommendations for improving the international standard ISO 19906 and SNIP RK 3.04-40-2006.

INFLUENCE OF OIL AND GAS FIELDSON SOILS OF THE CRYOLITHIC ZONE OF THE WESTERN SIBERIA NORTH

In the territories of Purovsk, Nadym, Tazovsk and Yamal areas the problem of pollution of soils by hydrocarbons and damage of the permafrost zone soil-vegetable cover is particularly acute. The anthropogenic stress created by oil and gas field facilities is significant currently and will grow in the nearest future which at the present level of technologies can aggravate the existing ecological situation.

USE OF WIRELESS NETWORKS FOR GAS FIELDS AUTOMATION

The largest gas and condensate fields (GM and GCM) of Russia located in the Far North region with hard climatic conditions and the lack of infrastructure, including power supplies. Therefore, the main problem during the development and operation of GM and GCM automation systems is the absence of wired communication channels between the individual gas field facilities, such as wells and treatment plant. This problem is solved by using the wireless data transfer technologies. Today there are a lot of different systems for wireless data transmission, differing transmission distance, its maximum speed, the technology used. It’s analyzed the existing technologies and systems in this article. The requirements for the operating conditions of wireless channels of communication technology used are formulated too. The best option is the use of wireless sensor networks (WSN). It is a distributed self-organizing network, consisting of a variety of sensors and actuators connected to each other via radio. This network meets the basic requirements for the gas fields, namely, it can be combined to thousands of electronic devices, cover the space of a few kilometers due to the ability of nodes to relay messages and embedded in automation systems in the area between the managed process and the SCADA system. The authors recommend to use the system Swift, developed by the Russian telecommunications’ company Swift Telematics. The main factors affecting the reliability of operation of the FSU, as well as its individual components, are considered. The ways to improve it are shown.
