| 摘 要： | 马营堡井田基本构造形态为一单斜构造,区内不同岩性地层的电阻率、密度、声波时差及伽马值均有明显差异,其中煤层的电阻率、密度及声波时差曲线均表现出出高异常及自然伽马低异常;而砂岩随粒度的变细及泥质含量的增加,自然伽玛逐渐增大。依据该区岩性基本物性特征,确定了井田内新生界与基岩、下石盒子组与山西组分界及主采煤层4、9号等主要标志层的响应特征。这些地层标志在测井曲线上形态,可作为该区地层对比的重要依据。

| Abstract: | The basic structural form in the Mayingbu minefield is a monocline.The resistivity,density,sonic differential time and gamma in different strata in the area have distinct differences.In which,coal seam resistivity,density and sonic differential time are all indicative of high anomaly and gamma-ray low anomaly;while along with grain-size fining and argillaceous composition increasing in the sandstone,gamma-ray increasing gradually.Based on basic physical property characteristics of strata in the area have de... |
