Status-quo,potential,and recommendations on shale gas exploration and exploitation in China
摘要
Abstract
China's shale gas resources are mainly distributed in the Sichuan Basin and its periphery,middle Yangtze Block,Tarim Basin,Guizhong Depression,and the Ordos Basin.Innovations in geological theories and breakthroughs in engineering technologies have propelled the rapid development of China's shale gas industry.To effectively alleviate the supply-demand imbalance of oil and gas in China,it is crucial to keep expanding the shale gas exploration and exploitation fields to achieve a leap forward in the shale gas industry.The results of this study indicate that by the end of 2023,China had achieved cumulative proven geological reserves of shale gas of 2.96×1012 m3 and an annual shale gas output of around 250×108 m3,which,all originating from the Wufeng-Longmaxi formations in the Sichuan Basin and its periphery,account for about 15%and 13%of the country's total proven geological reserves and annual output of natural gas,respectively.The shallow to moderately deep marine strata in the Sichuan Basin and its periphery are recognized as the major contributor to the stable production and further reserve growth of shale gas.Currently,China is expanding shale gas exploration and exploitation into new areas,including deep to ultradeep strata in the Sichuan Basin,normal-pressure marine facies in structurally complex regions outside the basin,the Cambrian and Permian sequences,and new-type reservoirs like those of the continental and marine-continental transitional facies.It is predicted that by 2035,the annual shale gas output will reach up to 1 000×108 m3,representing about one-third of China's total annual production of natural gas.It is recommended to intensify domestic shale gas exploration and exploitation,and enrich the development of multi-type shale gas reservoir geological theories and supporting key technologies,which are expected to significantly drive the additions to reserves from reserve growth of shale gas.China's geological resources of shale gas are estimated at 118.67×1012 m3,holding enormous potential for further exploration and exploitation.关键词
