桥口、白庙地区油气分布与成藏模式

OIL-GAS DISTRIBUTION AND RESERVOIR-FORMED PATTERNS IN QIAOKOU AND BAIMIAO AREA

本文依据桥口、白庙地区的油气分布特征、油气性质、有机质类型、热演化史、流体势分布、构造发育演化和火山侵入作用等资料，提出了该区的油气成藏模式。指出桥口地区属于聚集－破坏－聚集型成藏模式，而白庙地区则为单一的晚期聚集型成藏模式。这对该区域的油气勘探有一定指导意义。

Based on analysing the data of oil gas distributive features, organic matter types,thermal evolution history. fluid potential distribution, structural growth evolution and volcanic invading action, it is proposed that the reservoir-formed pattern in Qiaokou belongs to the type of gathering-destroying-gathering and Baimiao area is singular later period type,which is of guiding significance for explorating the oil-gas in the areas.
