Comprehensive geophysical technology on Oil & gas resources of pre-cenozoic residual basin in Chinese marine area
海区前新生代残留盆地油气研究的综合地球物理技术

There is great potential of hydrocarbon resources in Pre-Cenozoic residual basin in China. It has been proved by exploration practices, but there still are many technical difficulties. This paper introduces the study methods and techniques aim to residual basin exploration by the support of 863 Project in recent years. It includes the techniques of seismic data collection; curve ray based pre-stack imaging of complex geology structure, and thickness extraction of residual basins. These techniques have been tested in China seas areas and got good effects.
