中国煤层气开发利用现状及技术进展

Development and utilization status and technical progress of coalbed methane in China

通过对我国煤层气开发利用和技术发展现状的分析和调查研究,总结了我国煤层气产业发展现状及特点。分析表明:"十二五"期间,我国煤层气勘探开发成果显著,煤层气产量稳步增长,沁水和鄂东等产业基地建设逐步完善,中低阶煤的煤层气勘探开发取得突破。但整体上未能完成"十二五"规划制定的产业发展目标;同时,煤层气开发技术取得了快速发展,井型多样化、压裂的规模化、排采的精细化智能化,尤其是多分支水平井钻井技术、水平井分段压裂技术以及碎软构造煤地区煤层气开发技术取得了优异成效;最后,针对我国煤层气产业发展现状,提出了我国煤层气未来产业发展方向。

Through the analysis and investigation of development and utilization status and technical progress of coalbed methane in China,the paper summarized the status and features of the coalbed methane industry development in China.Analysis shows that,during the ＂12 th five year＂plan period,the exploration and development of coalbed methane in China have a good achievement, the coalbed methane production increased steadily.Qinshui and eastern Hubei and other industry base construction gradually improved,the exploration and develop-ment of coalbed methane in medium and low rank coal has made a breakthrough.But on the whole failed to complete the industrial development goals of the ＂12th five year＂ plan.Secondly,the development technology of the coalbed methane has made rapid development,di- versified well types, huger fracturing scale,fine and intelligentized production,especially mul- ti-branch horizontal well drilling technology,subgrade fracturing technology for horizontal wells,development technology of combed methane in the area of shattered soft structure, achieved excellent results.Finally,in view of the status of the CBM industry development in China,proposed the future development direction.
