重磁电综合物探技术在南方页岩气地质调查中的应用研究——以桂中坳陷鹿寨地区为例
|
摘要
广西一直以来面临着"缺煤、少油、无气"的窘境.本次研究工作是在"南方地区页岩气基础地质调查"的工作基础之上,通过对广西桂中坳陷鹿寨地区开展高精度重力、磁法以及大地电磁法综合物探剖面测量,结合地质、物性和钻探等成果资料,对获取的重、磁、电资料进行联合正反演综合研究,定性-定量解释推断了该地区富有机质泥页岩主要有利目标层系——下石炭统鹿寨组泥页岩层的分布、埋深和厚度等特征;并进一步了解了该地区的断裂构造展布特征,最终对该地区页岩气勘探的有利目标区带进行了圈定预测,为该地区下一步的页岩气基础地质调查工作提供了重要的物探依据.同时,也证实了该套物探技术方法组合能够在南方地区页岩气地质勘探工作中取得较为理想的勘探效果,值得推广应用.
Guangxi has been facing the awkward situation of "lack of coal, oil, less gas". The research work is in the "Southern shale gas basic geological survey work, with the profile work of integrated high precision gravity, magnetic and magnetotelluric sounding, combined with geological, physical properties and drilling data, to obtain is for joint inversion of gravity,magnetic and electric data comprehensive research, quantitative interpretation the characteristics for the region of rich organic matter under the favorable target strata of the shale-carboniferous group distribution, buried depth and thickness of mud shale etc. In addition, the characteristics of fault tectonics in this area were further understood, and the favorable target zones of shale gas exploration in this area were finally delineated and predicted, which provided important geophysical basis for the next geological survey of shale gas in this area. At the same time, it has been proved that the combination of geophysical techniques and methods can achieve ideal results in shale gas exploration in southern China, which is worthy of popularization and application.
