Progress and Prospect of Researches on Drilling Fluid Technology for Deep CBM Drilling
摘要
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.关键词
