【摘要】 通过对我国煤储层参数获取方法的分析,选取注入/压降测试方法作为研究重点,对试井参数选取、测试过程等进行介绍,通过注入/压降和原地应力测试,以四川省某煤层气参数井为例,获取该井的储层压力、渗透率、表皮系数、破裂压力、闭合压力等参数,并对煤储层特征进行评价,为该区煤层气生产潜能评价和开发试验提供可靠参数依据。更多还原

【Abstract】 Through the analysis of coal reservoir parameter acquisition method,then coalbed methane injection/pressure drop testing method was as the research focus,the test parameters selection,test process and so on were introduced.A parameter well in Sichuan Province as an example,the well reservoir pressure and temperature,permeability,skin factor,fracture pressure,closure pressure and other parameters were obtained through the injection/pressure drop testing and in-situ stress testing.And to evaluate the characteristics of coal reservoir,it provided reliable parameter for the evaluation and the production potential and development test of the area.更多还原
