摘要
利用自然伽马(HG)、人工伽马(HGG)、视电阻率(KLW)和自然电位(DZW)等测井参数对不同岩性地层的响应特征,结合岩心鉴定,煤样测试等资料,对柴达尔井田含煤岩系进行识别和对比。通过对40余孔测井资料分析,总结出该区识别不同岩、煤层的测井曲线典型特征及类型,并以此对该井田的侏罗系陆相含煤地层进行岩、煤层层序划分与对比。在该井田共划分了十三个标志层和七个粒序旋回,并认为发育于不同区段的M0和M1煤层是两个不同时期沉积体系产物。
By the agency of response characteristics of natural gamma-ray （HG）, gamma-gamma （HGG）, apparent resistivity （KLW） and self-potential （DZW） logging parameters toward different strata, combined with core identification, coal sample testing carried out Qaidar minefield coal-bearing strata identification and correlation. Analyzed 40 more boreholes well logging data, summed up typical characteristics and types of different rock and coal in the area, worked out the minefield＇s Mesozoic Jurassic System terrestrial coalbearing strata sequential division and correlation. 13 marker beds and 7 graded-bed cycles have been divided and considered that the M0 and M1 coal seams in different sectors belong to different stage sedimentary systems.
