浅层油源断裂油气运聚时期预测方法及其应用
Research on the Prediction Method of Hydrocarbon Migration and Accumulation Period Controlled by Oil Source Fault in Shallow Layerand Its Application
摘要
Abstract
In order to study the hydrocarbon enrichment law of shallow oil source fault in hydrocarbon-bearing ba-sins,a variety of factors affecting the hydrocarbon migration and accumulation along shallow oil source fault were comprehensively considered,and a set of prediction methods applicable to the hydrocarbon migration and accumula-tion period controlled by oil source fault in shallow sandy mudstone formations was established.It is clarified that the hydrocarbon migration and accumulation period in shallow oil source fault should be the superposition of the pe-riod of hydrocarbon transportation in oil source fault,the period of seepage in all regional mudstone caprocks crossed by the faults,and the period of closure formation in shallow regional mudstone caprocks.The method was applied to the shallow Guantao Formation stratum of the Manqikou Sag in the Bohai Bay Basin,and it was clarified that the hydrocarbon migration and accumulation period in the Gangdong Fault was from the middle to the end of the deposition of the Minghuazhen Formation.The determination of the hydrocarbon migration and accumulation period is of great significance in guiding the hydrocarbon exploration at the shallow oil source fault in hydrocarbon-bearing basins.关键词
