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。
In the outcrop of marine carbonate rocks in southern China, there are many problems that need to be explored and studied in order to carry out geophysical exploration work with great difficulties, data processing and interpretation. Taking the Pipze area in Lichuan, Hubei Province as an example, based on the analysis of the known parameters of the ground and the underground, the geological patterns are established by using several key seismic sections to constrain the MT, EMAP and gravity inversion , To carry out comprehensive geological interpretation of geophysical data under complex conditions. The results of comprehensive interpretation greatly enriched the information of geological structure in the work area and provided a large amount of detailed and informative data for carrying out structural analysis of the basin and carrying out trapping description and evaluation so as to further improve the reliability of geological interpretation.
