【摘要】 在我国南方海相碳酸盐岩出露区 ,开展地球物理勘探工作难度大 ,资料处理、反演解释存在许多需要探索和研究的问题。文中以湖北利川鱼皮泽地区为例 ,在分析已知地面及井下物性参数基础上 ,利用几条骨干地震剖面建立地质模式 ,约束大地电磁 (MT)、电磁阵列剖面 (EMAP)和重力反演 ,开展复杂条件下地球物理资料的综合地质解释。综合解释的结果极大地丰富了工区地质结构信息 ,为开展盆地区域构造分析、进行圈闭描述与评价提供了大量翔实的资料 ,从而进一步提高了地质解释的可靠性。更多还原

【Abstract】 The geophysical exploration in cropped marine carbonatite area in South China is very difficult;and there are many tough problems that must be researched in the processing, inversion and interpretation of geophysical data. Yupize area in Lichuan City of Hubei Province is taken as an example to describe the technique.With the analysis of known surface and borehole geophysical data,some main seismic sections were used to construct geology model, which was adopted to restrict magnetotelluric section, electromagnetic array profile and gravity inversion. Then, the comprehensive geological interpretation of geophysical data in complex conditions was achieved very successfully. The comprehensive interpretation result enriches geological structure informations in the area,and offers a great deal of full and accurate data for regional tectonic analysis, and description and evaluation of hydrocarbon trap, thus improving the reliability of geology interpretation.更多还原
