Controlling Effect of Hydrocarbon Migration Systems on Hydrocarbon Migration and Accumulation in Linfanjia Low-uplift Zone
摘要
Abstract
Taking Linfanjia low-uplift zone in Jiyang Depression as an example,starting with the hydrocarbon distribution pattern,the characteristics of hydrocarbon migration factors were analyzed,the hydrocarbon accumulation model in Linfanjia low-uplift zone was established,and the control effects of the hydrocarbon migration factors on the migration and accumulation of hydrocarbon were discussed.The research result shows that there are developed two oil source faults in the study area,and the change of fault activity and closure presents periodic episodic characteristic,which leads to the mode of "episodic spatial segmented migration".In addition,there are four types of unconformity lithological structure.Meanwhile,the unconformity "clearstory" plays an important role in the vertical migration of hydrocarbon.Based on the analysis of the characteristics and effectiveness of hydrocarbon migration systems and the characteristics of hydrocarbon distribution,the hydrocarbon accumulation mode of the study area is established,that is," faults linking source and reservoir-unconformity shunting-multiple migration systems-accumulating in multiple layers".Furthermore,Time-space effectiveness of oil source faults controls the oil source condition and the filling pattern and range of hydrocarbon in different layers,while the vertical shunting of unconformity ‘clearstory'controls different accumulation characters of hydrocarbon in different layers.关键词
