摘要
山东省煤田地质局第二勘探队在星村井田应用PSJ-2型数字测井仪进行了煤田数字测井工作,通过多种参数综合定性、定厚解释,测量参数有电阻率、自然伽玛、密度(伽玛长、短源距)、声波速度、井径、井斜等根据不同煤层顶底板岩石的物性条件,选用界面清楚、定性可靠、符合本井田物性规律的参数方法的解释成果,作为煤层厚度的确定成果,经钻探取芯证实是可靠的。
The Shandong Province Bureau of coal geological second exploration team conducted coalfield digita llogging work in Xingcun coal mine using PSJ-2 type digital logging instrument, through a variety of comprehensive qualitative parameters and thickness, measuring parameter interpretation, including the resistivity, natural gamma,density (Gama long and short spacing), acoustic velocity, borehole diameter, etc. according to the different coal seam roof and floor rock physical conditions, the interface is clear, reliable qualitative and conform to the law of the property parameter interpretation method, the core drilling proved that the results are reliable, and can be acted as the determined achievement of the coal seam thickness,.
