Development progress,challenges,and strategies for CBM/CRG in the eastern margin of the Ordos Basin
摘要
Abstract
Coalbed methane(CBM)/coal-rock gas(CRG)in the eastern margin of the Ordos Basin serves as a critical replacement in China's natural gas sector.However,it has been marginally proved and uneconomically developed due to its complex geological characteristics and poorly adaptive engineering techniques.To address these challenges,this paper systematically reviews the development history of CBM/CRG,particularly the exploration and development practices of CRG in the eastern margin of the Ordos Basin since 2019.Furthermore,this paper identifies the current problems and challenges facing the CRG development and proposes corresponding solutions and suggestions.The following results are obtained.First,in the Daji block,eastern Ordos Basin,innovative theoretical understanding of the accumulation and enrichment of CRG has been preliminarily established,along with six geological-engineering integrated efficient development supporting technologies,which have supported the construction of China's first CRG field with an output of one million tons of oil equivalent.Second,the rapid development of CBM/CRG in the eastern margin of the Ordos Basin is mainly challenged by the difficulty in cost-effective development of medium–shallow CBM,numerous theoretical and technical bottlenecks in the exploration and development of deep CRG,and insufficient policy support for the CBM/CRG industry.Third,targeted solutions and suggestions are proposed as follows:(1)enhancing the evaluation of favorable areas for medium–shallow CBM exploration and development to improve single-well production and economic efficiency;(2)strengthening theoretical and technological research on CRG exploration and development to book more additional reserves and achieve efficient development;and(3)intensifying policy support for the CBM/CRG industry at multiple levels,helping it become a new growth driver for China's natural gas production.The study concludes that by focusing on theoretical and technological progress,strengthened supporting policies,and improved development efficiency,the CBM/CRG in the eastern margin of the Ordos Basin is expected to achieve higher-quality development,providing a theoretical foundation and demonstrative example for achieving additional CRG reserves/production across the country.关键词
