【摘要】 新立油田处于松辽盆地中央坳陷区最西端,扶杨油层包括扶余油层以及杨大城子油层,油层厚度约500 m,是新立油田主要目的层。通过岩心、测井、录井、钻井、试油以及PVT资料的研究,对油藏的构造、沉积、储层、油层展布有系统性认识。研究认为,储层物性条件差,孔隙度与渗透率都很低;油层分布范围广,平面连通性好,但单井有效厚度差异大,主体中心区厚度较大,并向周边逐渐减薄。油藏的控制因素由于方向的不同而不同:东西向油藏主要受到构造和断层因素控制,形成构造油藏以及断块油藏;南北向油藏含油范围与构造范围分布不统一,主要受岩性控制,发育有岩性油藏。新立油田扶杨油层整体属于构造——岩性油藏。在未来的工作中,要加大沉积预测以及地震方面的研究,从而形成综合性的地震地质分析和一套切实可行的预测含油有利区的方法。更多还原

【Abstract】 A new oil field in the central depression in Songliao basin of the westernmost,Fuyang oil layer reservoir including Fuyu and Yangdachengzi oil layer,oil layer thickness of about 500 m,is the main objective of Xinli oilfield layer.Through core analysis,logging,drilling,well logging,oil testing and PVT data to the study of oil reservoir,structure,sedimentation,reservoir,reservoir distribution haav a system of knowledge,research thought,Reservoir condition is poor,the porosity and permeability are low;single well reservoir effective thickness difference is big,wide distribution,plane has good connectivity,the center of the body area of greater thickness,and surrounding gradually thinning.Reservoir controlling factors vary as the direction: east-west,mainly by reservoir construction and factors that control fault,tectonic fault block oil reservoir and reservoir;north to south,the scope and structure the scope of the reservoir oil distribution is not uniform,Mainly controlled by lithology,lithologic reservoir development there.In general,are constructed-lithologic reservoir.In future work,to increase the deposition and earthquake prediction research to form a comprehensive analysis of earthquake geology,To form a viable way to predict favorable method.更多还原
