    神木—双山地区古生界含气层系岩石地层划分

    The division of the Paleozoic strata in Shenmu-Shuangshan area

    • 摘要: 提要:鄂尔多斯盆地东部神木—双山地区古生界地层含气层系多,地层在横向及纵向上变化复杂,为了更加准确评价该区域含气规模以及特征,本文在岩石地层单元定义基础之上,结合测井、地质等资料,对神木—双山地区古生界含气层系岩石地层的划分进行了重新认识,论述了各个含气层系及标志层的地质和测井响应特征,讨论了测井资料在地层划分及对比时的优越性和不足之处。

       

      Abstract: Abstract:There exist many gas formations in the Paleozoic strata of Shenmu-Shuangshan area within eastern Ordos Basin. Horizontal and vertical variations in these formations are complex. In order to make an accurate evaluation of the sizes and characteristics of the gas formations, this paper deals with the division of the formation on the basis of the definition of the stratigraphic unit in combination with the logging and geological data. Logging and geological features of the gas formation and the index horizon as well as advantages and shortcomings of applying logging data in the division of gas formations are also discussed in detail.
