贵州省金沙县安洛煤矿勘查区9号煤储层参数研究

Reservoir Parameters Research of No.9 Coal Seam of Anluo Coal Mine Exploration Area in Jinsha County of Guizhou Province

通过对金沙县安洛煤矿区7-3孔进行试井测试,根据测试参数及结果绘制关井压降曲线双对数-导数曲线、半对数曲线图、关井压降半对数拟合检验曲线,从而对井筒附近渗透率、9号煤的煤岩层物性、地层压力系数、煤层破裂压力及梯度、煤层闭合压力及梯度等进行分析,综合研究9号煤储层参数。

Based on the well test in Borehole 7 - 3 of Anluo Coal Mine in Jinsha County, the paper finishes the double-logarithmic and derivative curve and the semi-logarithmic curve, and the semi-logarithmic fitting test curve according to the parameters and results of the test, analyzes the permeability around the shaft, the properties of coal and rock seam of No. 9 coal seam, the pressure coefficient of strata, the fracturing pressure and gradient of coal seam and the closed pressure and gradient of coal seam, and comprehensively studies the reservoir parameters of No. 9 coal seam.
