测井曲线重构在煤田地震反演中的应用
|
摘要
该文简述了测井曲线重构过程,并选用淮北某煤矿采区为例,对不具备约束条件的钻孔进行了测井曲线重构,使重构后的波阻抗曲线能够突出煤系地层不同岩性及含水砾岩的波阻抗特征,并用其进行了多井约束反演,岩性预测取得了较好的效果。
In the paper,we simply describe the process of logging curve rebuilding,and then taking a coal mine in Huaibei mining area for an example,we rebuild the logging curve of wells which do not have the condition of restraint,so that the rebuilt impedance curves can highlight the wave impedance characteristics of different layers of coal-bearing and the water conglomerate,and we act a multi-well restraint inversion,which get a good results of the lithology prediction.
