鄂西残留盆地综合地球物理应用研究
|
摘要
通过多种地球物理资料,包括地震、重力、航磁和电法等资的料综合运用,深入揭示研究区地质结构和构造面貌。采用地震造前深度偏移技术,使复杂构造正确成像。采用测井数据约束地震资料反演,预测储层横向展布。从而精细研究有利圈闭特征,指导鄂西残留盆地天然气勘探。
Geologic structures and tectonic configuration in western Hubei are denoted thoroughly by comprehensively u-sing the geophysical data, including seismic, gravitational, aeromagnetic surveying and electric data. The technique of seismic pre-stack depth migration is used to correctly implement the complex structural imaging. Lateral reservoir extension is predicted by restricting the inversion of seismic data with logging data, thus favorable trap characters are studied carefully, which would be a guidance for natural gas exploration in the residual basin.
