川东杂卤石的地球物理响应特征及地震勘探技术
Characteristics geophysical response of polyhalite and its seismic exploration technology in east Sichuan Basin, China
摘要
Abstract
Triassic in Sichuan Basin is the main production formation of polyhalite,which generally has a buried depth of 1～4 km,and a single layer thickness of 1 m.This paper discusses the geophysical technical method of quantitative prediction of polyhalite.However,seismic characteristics of polyhalite in the basin are not well studied at present.So,the exploration of polyhalite in this area is extremely challenging.Various seismic exploration technologies,such as layer flattening technique,impression method,seismic attribute technology and seismic motion inversion technology,are studied in consideration of the particular physical properties of polyhalite.A technique process of polyhalite quantitative prediction is proposed in the paper so as to provide theoretical and technical support for Triassic polyhalite exploration and development in Sichuan Basin.Since the genesis and the migration of polyhalite has a complex relation with fault,high resolution AFE technique is used for the prediction of fractures.It proves that the polyhalite in the region is related to fractures.关键词
