姬塬油田马家山地区长4+51亚段油藏特征及主控因素
Reservoir Characteristics and Main Controlling Factors of Chang 4+51 Subsection in Majashan Area,Jiyuan Oilfield
摘要
Abstract
In order to deepen the understanding of reservoir characteristics and main controlling factors of Chang 4+51 subsection in Majashan area of Jiyuan oilfield,a comparative analysis was made in terms of source rock structure,dominant sand body and physical properties.The analysis shows that the area is located in the hydrocarbon genera-tion center of source rock of Chang 7 section,which has a favorable foundation for reservoir formation.The super-imposed dominant sand body facilitated the main channel of hydrocarbon migration from source rock of Chang 7 section to Chang 4+51 subsection.The matching between the high permeability sand body at the confluence of distributary channels and the near east-west row nose uplift structure forms a favorable place for oil accumulation.The Chang 4+51 subsection reservoir is mainly lithologic under the control of many factors,and the longitudinal sand body structure determines that oil is enriched in the Chang 4+521 small layer.关键词
