三维地震勘探在准格尔煤田红树梁井田的应用

准格尔煤田位于内蒙古中西部,红树梁井田位于准格尔煤田南端。为了进一步查明井田内煤层的赋存、构造、煤层风氧化带等地质情况,为煤矿生产、安全提供地质保障,对该区进行三维地震勘探。使用三维地震勘探的方法查明了测区内主要可采煤层4煤、5煤、6-1煤和6煤层的赋存形态和深度,解释了断层24条,圈定了煤层风氧化带的范围,解释了6煤层的分叉边界。

3D Seismic Prospecting Applied in Zhungeer Coal Field Hongshuliang Well Field

Zhungeer coal field is located in the midwest of inner Mogolia.Hongshuliang well field is located in the south of Zhungeer coal field.In order to find out more geology conditions of the storage,structure,coal seam zone of weathering,and to provide the geology safeguard,3D seismic prospecting was made.The storage conditions and depth of the main minable coal seam such as 4coal seam,5coal seam,6-1coal seam and 6coal seam in the testing zone has been found out with 3D seismic prospecting.And 24 faults has been explained,the scope of coal seam wind oxygenized belts has been found,and the bifurcate boundaries of 6coal seam has been explained.
