Helium resources accumulation regulations and their development prospects in China

Helium is a globally scarce strategic resource that is relevant to national economies and the development of high-tech industries, and China primarily depends on imported helium for its industrial applications. Therefore, there is an urgent demand for clarifying helium formation and enrichment patterns, searching for helium-rich fields, and realizing China's helium resource inventory and development potential. This article analyzes the reservoir characteristics and accumulation conditions of typical helium-rich fields in China, and clarifying the origin and source of helium as well as the main controlling factors of helium enrichment. It was recognized that helium in natural gas in China mainly comes from crustal sources. Relatively shallow buried ancient U–Th-rich granite basement or intrusion, large and stable ancient uplift or submarine formed in the early period, good overburden of huge thick paste-salt rock or mudstone cover, and channels connecting the basement and reservoir, were the main controlling factors of helium enrichment. Four types of helium-rich gas reservoirs, namely helium-rich conventional gas, helium-rich shale gas, helium-rich non-hydrocarbon gas, and helium-rich water-soluble gas, have been modeled and predicted to be helium-rich favorable exploration areas. Based on this analysis, the prospect of helium resource development in China has been analyzed. It was proposed that the exploration of helium-rich fields and the comprehensive development and utilization of medium- and low-abundance helium resources are important ways to increase the domestic helium production in China in the future.

Geochemical Characteristics of Helium in Natural Gas From the Daniudi Gas Field, Ordos Basin, Central China

Helium-bearing gas is accumulated in the Lower Ordovician, Upper Carboniferous, and Lower Permian reservoirs of the Daniudi gas field in Ordos Basin, and the helium concentrations and isotopic compositions are investigated in order to reveal the abundance and origin of helium. Geochemical characteristics indicate that the natural gas from the Daniudi gas field has helium concentrations of 0.0271–0.1273%, with R/Ra ratios of 0.007–0.072. The 4He/20Ne ratios range from 848 to 17,000, which are substantially higher than the ratio of air or air saturated water. The proved helium reserves of the Daniudi gas field exceed 100 × 106 m3, suggesting an extra-large helium gas field. Helium in the field is of crustal origin and derived from the radioactive decay of U and Th in the rocks and minerals, with no significant contribution by atmospheric or mantle-derived helium. The natural gas in the Daniudi gas field displays the characteristics of typical crustal helium, which is consistent with the gases from cratonic basins (Ordos, Sichuan, and Tarim) in China, whereas the gases from rift basins (Songliao, Bohai Bay, and Subei) have experienced a significant addition of mantle-derived helium.

Distribution law of helium in Leshan-Longnvsi paleo-uplift in Sichuan Basin, China

The Weiyuan and Anyue large gas fields discovered on the Leshan-Longnvsi paleo-uplift in Sichuan Basin have the oldest marine gas reservoir discovered in China so far, and Weiyuan is also the first gas field to utilize helium resources in China. The Helium in natural gas of Leshan-Longnvsi paleo-uplift belongs to crust-derived helium formed by radioactivity, and its content distribution shows obvious regularity. The content of helium is highly correlated with the age of reservoir in the same gas field, and the helium content is gradually increased from the top to the bottom. However, the content of helium in natural gas presents significantly different in various tectonic units. The content of helium in Anyue gas field developed on Gaoshiti-Moxi structure is very low. The average contents of Sinian and Cambrian are 0.0356% and 0.0078%, respectively. The content of helium in Weiyuan gas field developed on Weiyuan structure is relatively higher, and the average contents of Sinian and Cambrian are 0.28% and 0.18% respectively. The high helium content of natural gas in Weiyuan gas field is related to the large-scale granite body developed on the basement on the one hand and the water-soluble gas accumulation on the other hand. The main gas reservoirs in the Weiyuan gas field and adjacent areas are located in the Sinian system. From the slope area to the high point of the Weiyuan structure, the helium content has increased significantly. With the tectonic movement of the Himalayan period, the Weiyuan area is greatly uplifted, causing structural traps. Natural gas dissolved in the water, including helium gas, is decomposed by decompression, and the released gas is trapped, then released gases accumulated in traps and thus formed Weiyuan gas field with high content of helium.

Discussion on Evaluation Method of Helium Resources in Natural Gas

In view of the importance of helium resources and the lack of evaluation methods, the resource evaluation method for helium in natural gas is found and summarized. Helium gas is associated with oil and gas, and generally exists as a component of natural gas. It has important industrial value and is used in many fields. At present, the helium resources are scarce in China, the application of the extraction of helium gas from natural gas is less. Based on sorting and summarizing the evaluation methods of natural gas, choose the resource evaluation method that can be applied to helium, and evaluate the resource of helium in natural gas based on the natural gas evaluation method. Finally, select the target area to select the evaluation parameters and control the reserves calculation, to verify the feasibility of the method. Through verification, the volumetric method is an accurate and reliable evaluation method for the helium gas resources in natural gas.

Mantle-Derived Methane Homologue, Carbon Dioxide and Helium in Natural Gases from Songliao Basin, China

Whether abiogenic (inorganic) actions can form petroleum and natural gas reservoirs has been a debatable problem for over a century in the academy circle. Gold (1979) proposed deep-earth gas hypothesis. Wang (1983, 1989, 1997) discussed the geochemical characteristics of deep-earth gas. Jenden et al. (1993) proposed three specific analytical criteria to identify mantle-derived hydrocarbons in oil and gas field. The isotopic composition characteristics of methane homologue, carbon dioxide and helium in natural gases from Songliao Basin, China will be discussed in this paper.

3He/4He ratios and heat flow in the continental rift-valley, eastern China

Heat flow and the origin of helium in natural gases from fault basins of the continental rift-valley in eastern China are discussed in terms of helium isotope geochemistry.3He/4He ratios in natural gases from the rift-valley range from 2.23 × 10−7 to 7.21 × 10−6, which are directly proportional to the concentration of helium and ΣNHC/ΣHC ratio in natural gases. Geological and isotope geochemical data suggest that helium in natural gases consists predominantly of crustal radio-genic and upper mantle-derived helium. In a simple mixing pattern between crustal He and mantle-derived He, mantle-derived helium in natural gases would account for 10–60%. Calculated values for heat flow (Q) range from 59.7 to 82.4mWm−2, of which about 60 percent in the rift-valley is derived from the upper mantle. Natural helium reservoirs would be found in the areas where the upper mantle uplifted greatly and heat flow is large in the continental rift-valley.

Relation of Radioactivity, Organic Content, and Sedimentation

A comparison between the radioactivity and organic content of 510 samples of sedimentary rocks indicates a marked relation between certain types of organic content and radioactivity. Marine oil shales are associated with exceptionally high radioactivity, coals with abnormally low radioactivity, and other types of organic matter with intermediate radioactivities. An analysis of the material balance between sedimentary and igneous rocks indicates that the sediments should have about the same radioactivity as the igneous rocks from which they were derived; the averages of the writer's tests seem to confirm this conclusion if the igneous source of the sediments resembles a granite. An analysis of the data bearing on the radioactivity of deep-sea deposits and oil shales indica es no evidence of a general increase in radioactivity with slowness of deposition. The bearing of the new data on the origin of oil and of the helium in natural gas is discussed.

Helium in Natural Gas

THE researches of H. P. Cady and D. F. McFarland in 1905 on some natural gas from Kansas led to the interesting discovery of the presence of helium in that gas, a fact of which advantage was taken afterwards by the United States military authorities during the later stages of the war. In 1915 the natural gas resources of this country were investigated for a similar purpose under the direction of the late Sir William Ramsay, and those of Canada were also examined, but in both cases the efforts were unsuccessful. The dangers attending hydrogen-filled aircraft were obvious from the fate of many of the German Zeppelins, so that the possibility of extracting sufficient quantities of an incombustible gas such as helium (admirably suited in every way to the peculiar requirements of lighter-than-air machines) was too important to be ignored.
