断陷盆地陡坡带高精度地震勘探技术应用
High-precision Seismic Exploration Techniques and Application on the Abrupt Slope Belt of Faulted Basin
摘要
Abstract
Taking Biyang Sag in Henan province as example, based on the need of the pre-stack migration processing and analysis of the physical mechanism and characteristics of seismic wave scattering field in large section, a scattering wave equation forward is used. The methods for acquisition are optimization parameters model forward technique, and some technical measures for solving the excitation energy in piedmont belt of the sag. For handling method, the applications of fine velocity modeling based on pre-stack depth migration imaging method is used. For interpretation, based on visual constructed map, the distribution of steep sand-conglomerate and developmental period are analyzed, and the distribution of a new sand-conglomerate horizon zone is predicted through the groove and fan corresponding theory, combined with seismic facies analysis, the layer equalize the level of slice analysis, attribute analysis and other methods etc. According to research result more wildcat are obtained successful through drilling, and two oil-rich block in the southern abrupt slope belt of the sag are found.关键词
