摘要:
黔西松河井田主采煤层注入/压降测试时，施工设计、现场操作不规范等因素导致测试分析结果与真实值存在偏差，影响煤层气储层评价的客观性。以12#煤层为例，介绍了松河井田注入/压降测试、原地应力测试设备、解释方法及施工过程，对注入/压降、原地应力测试结果进行分析，获取了储层物性特征及地应力参数。结果表明，黔西松河井田12#煤层储层压力、破裂压力及闭合压力梯度均为正常压力系统，拟合计算渗透率0072 5 mD，为低渗储层；通过分析井筒储集系数认为，封隔器失效或井下关井失败是造成该煤层测试曲线失真的主要原因，同时封隔段内的围岩也可能对测试结果造成偏差。该分析方法为后续煤层气勘探开发工作提供了思路。
Abstract:
In order to obtain the physical property characteristics and insitu stress parameters of the main coal seam in Songhe minefield, West Guizhou, and provide the basis for the subsequent exploration and development of coalbed methane, taking 12# coal seam as an example, the equipment, interpretation method and construction process of injection/pressure drop test and insitu stress test adopted in Songhe mine field are introduced. The test results are analyzed, and the coal seam permeability, reservoir pressure, skin factor and investigation radius are obtained and reservoir temperature, fracture pressure and closure pressure. The reservoir pressure, fracture pressure and closure pressure gradient of 12# coal seam are normal pressure system strata in this area, and the permeability of 12# coal seam is 0072 5 mD is a lowpermeability reservoir; through the analysis of wellbore storage coefficient, the test results of 12# coal seam of the test target coal seam may be distorted due to packer failure or downhole shut in failure, human factors, engineering factors, coal seam thickness, coal structure, surrounding rock and other reasons, which need to be further identified to eliminate interference for subsequent CBM exploration and development work.
