| 摘 要： | 松达煤田位于巴基斯坦伊斯兰共和国信德省塔塔区（Thatta district，Sindh province，Pakistan），地层自老至新由由侏罗系Chiltan组，古新统Bara组、Lakhra组，始新统Laki组和第四系组成。通过对松达煤田煤岩层测井物性参数的统计和曲线形态的分析，总结出该区煤岩层测井曲线独有的物性特征。根据密度、三侧向电阻率、自然伽马、声波等测井曲线在煤层、灰岩、砂岩、泥岩、细砂岩等岩性上的组合特征，进行了岩煤层的对比。全井田自上而下共解释分煤层组11个与灰岩层组3个，其中对6个较发育煤层进行了详细的说明。

| Abstract: | The Sonda coalfield is located in the Thatta District, Sind Province, Pakistan, from old to new, strata have Jurassic Chiltan Formation, Paleocene Bara Formation, Lakhra Formation, Eocene Laki Formation and Quaternary. Through statistics of rock and coal well logging physical property parameters and analysis of trace configuration, summed up particular physical characters in the area. Based on combination features of laterolog-3 resistivity, gamma-ray, sonic traces on coal seam, limestone, sandstone, mudstone, fine- grained sandstone, carried out rock and coal seam correlation. Interpreted 11 coal slices, 3 limestone sets, detailed explaining to 6 better developed coal seams in the whole minefield. |
