大地电磁测深法勘探深层页岩气的数值模拟分析

Numerical Simulation Analysis of Deep Shale Gas Exploration Capability by Magnetotelluric Sounding

证实了大地电磁测深法在深层页岩气资源勘探可发挥其优势,实现精细勘探。采用数值模拟结合富有机质页岩电阻率数据统计,建立两种不同深度同规模的背斜储层三维模型,对所获得两个模型的视电阻率资料进行了分析。研究结果表明,两种模型的电阻率响应存在可识别差异,为大地电磁法用于深层页岩气资源勘探提供可靠依据。

This article will be about the magnetotelluric sounding verified for shale gas exploration ability.We know organic-rich shale resistivity data statistics,including the establishment of two different sizes anticline reservoir depth with a three-dimensional model,the numerical simulation method to calculate the apparent resistivity data obtained two models.The results show the theoretical response of the two models there are of differences,in which we can learn the magnetotelluric observation instruments will effectively identify such relative deviation for the magnetotelluric method to be applied to shale oil and gas exploration in reliable basis.
