摘要
西部凹陷CJ洼陷是辽河油田西部凹陷的主要生油中心之一,洼陷中储集砂体发育,具有优越的油气成藏条件。通过对该洼陷细微的地层、构造及沉积相分析,总结出了沙三中、下亚段和沙四段的砂岩、角砾岩及白云岩是该区的主力含油气储集岩,并通过地震反演资料分析,从纵横向上划定了储集层的空间分布规律,为该区下一步油气勘探指明了方向。
CJ Depression was one of the main oil-generating centers of Western Depression in Liaohe Oilfield,where developed reservoir sand body with excellent conditions for hydrocarbon accumulation. By analyzing fine strata,structures and sedimentary facies. It was summarized that sandstones and breccia and dolomite in Es3 and Es4 are the main oil and gas reservoirs. Based on the analysis of seismic inversion data,spatial distribution laws of the reservoirs are set by vertical and horizontal delimitations,it points out the direction for further petroleum exploration.
