春光探区油气地质特征与勘探技术分析

Analysis of Oil and Gas Geological Characteristics and Exploration Technology of Chunguang Exploration Area

论述了春光区块总体为南倾北抬的单斜构造,断层不发育。分析了沙湾组储层特征及其地震响应特征,阐明了岩性体圈闭及油藏识别的"亮点"技术模式,指出了"亮点"模式的形成机理及其适用条件、局限性,总结了沙湾组岩性油藏的勘探成效及其借鉴意义。

This paper discusses that the Chunguang block is a monocline structure with the south tilting and north uplifting,and the fault is not developed,analyzes the characteristics of the reservoir and its seismic response of Shawan formation,expounds the"bright spot"technique model of lithologic trap and reservoir identification,points out the formation mechanism of"bright spot"model and its applicable conditions and limitations,summarizes the effect and reference significance of the lithologic reservoir in Shawan formation.
