【摘要】：CAP油田所在区块构造上属于OM盆地,地表为丛林,区块面积299km2。产层为第三系砂岩、白垩系砾岩及裂缝基岩。至2013年4月底共完钻各类井33口,开发目的层M层系及C层系共有32口井,在非目的层B层有1口井。其中投入开发共28口井(水平井15口)。累积产油969.994Mbbl,累积产水91.474Mbbl,累积采出程度0.23%。CAP油田主要发育中生界和新生界地层,下伏前寒武系变质岩基底。中生界白垩系砾岩C层、新生界古近系的M层为主要含油层系,变质基岩为次要含油层系。白垩系砾岩C与下伏侏罗系和上覆古近系均为不整合接触,古近系M和Arr层之间为整合接触。利用地震、钻井、测井、开发数据以及地质模型等资料,参照SY/T6191-1996《稠油油藏描述技术要求》,根据稠油油藏注蒸汽开采特点,对CAP油田进行了精细油藏描述,主要研究内容包括地层划分与对比、构造、沉积环境、储层评价、油气水分布特征、流体性质、渗流物理特征、油藏压力及温度系统、油藏及流体热物理性质描述,储量计算及评价,三维地质模型修正与完善。
[Abstract]:The block structure of the CAP oil field belongs to the OM basin, the surface is the jungle, and the block area is 299 km2. The production layer is the Tertiary sandstone, the Cretaceous conglomerate and the fractured bedrock. By the end of April 2013,33 wells of various wells were drilled, and 32 wells were developed for the purpose of developing the target layer, and there were 1 well in the non-target layer B. Of these,28 wells (15 horizontal wells) were developed. The cumulative oil production is 969.994 Mbbl, the accumulated water yield is 91.474Mbbl, the cumulative yield is 0.23%. The CAP oil field is mainly developed in the Mesozoic and Cenozoic strata and the lower part of the Precambrian metamorphic rock base. The M layer of the middle and lower Cretaceous conglomerate is the main oil-bearing system, and the metamorphic base rock is the secondary oil-bearing system. The Cretaceous conglomerate C is not in full contact with the underlying Jurassic and the overlying Paleogene, and is in full contact between the Paleogene M and the Arr layer. Based on the data of seismic, drilling, logging, development data and geological model, reference is made to the technical requirements of SY/ T6191-1996 【学位授予单位】：东北石油大学
