摘要

摘要: 深层煤岩气已成为非常规天然气资源的重要组成部分，其储层具有非均质性强、割理及微裂缝发育、力学强度低等特点，在水平井实钻过程中易出现井壁失稳、携岩脱气困难、储层损害严重等问题，亟需研发适用于深层煤岩气井的关键处理剂及高性能钻井液体系，保障安全、优质、高效钻井。通过总结近年来深层煤岩气钻井液处理剂及体系的研究进展，结合钻井液体系应用效果，梳理分析各类型钻井液技术特点，展望深层煤岩气钻井液技术未来发展方向，对深层煤岩气钻井提质增效、非常规资源高效勘探开发，保障国家能源安全均具有极其重要的意义。

Abstract: Deep coalbed methane (CBM) has become an important part of unconventional natural gas resource development. CBM reservoirs are characteristic of strong heterogeneity, developed cleavage and microfractures, and low mechanical strength etc., which always result in problems such as borehole wall instability, difficulties in cuttings carrying and drilling fluid degassing, and serious reservoir damage etc. Key additives and high-performance drilling fluids for deep CBM development are in urgent need to ensure drilling with safety, high operational quality and high efficiency. This paper summarizes the progress made in recent years in the research of drilling fluid additives and systems for deep CBM development. Based on the effectiveness of the drilling fluid systems, the technical features of these drilling fluids are sorted and analyzed, the direction of future development of CBM drilling fluids is forecast, and these are of great importance to the high-quality high-efficiency deep CBM development, the high efficiency exploration and development of unconventional resources, and to the guarantee of national energy safety.
