Good protection of a coalbed methane reservoir can facilitate its exploitation and usage, cover Chinas shortage of oil and natural gas, cut greenhouse gas emissions, decrease environmental pollution and prevent mine accidents.Firstly, the damage mechanisms of a coalbed methane reservoir in the Qinshui basin of the Shanxi province were comprehensively analyzed using X-ray diffraction (XRD), a Scanning Electron Microscope (SEM), linear swelling test and hot rolling dispersion expenments, thin-section analysis, mercury penetration analysis, wettability measurements and sensitivity evaluations.Based on this work, pertinent protection counter-measure studies were conducted, the surface wettability modifier (SD-905) and water sensitivity inhibitor (SMYZ-2) were removed, and then a drilling method was developed for fluid from a coalbed methane reservoir in the Qinshui basin of the Shanxi province composed of 0.4%SD-905 + 0.5%SMYZ-2.This method was shown to cause only minimal damage to the permeability of the ingredient under a hygrometric state.

采用转子黏度仪初步研究了压裂液增稠剂疏水基改性羟乙基纤维素(HMHEC)基液体系的流变性,及其与HMHEC在基液中的结构间的关系.结果表明:HMHEC水溶液体系为剪切变稀的流体体系;HMHEC基液体系有较强的温度可逆性和剪切恢复性.HMHEC与HEC在不同剪切速率下，其基液的剪切黏度度均随剪切率的增大而减小。HMHEC基液体系具有温度可逆性，并且HMHEC通过可逆过程后，私度会相对大于基础黏度。
