【摘要】 秘鲁B1-AB＆B8区两个区块的年产量规模目前排在CNODC海外项目的第三位,加大对该项目的研究与技术支持力度,实现该油田的高效开发,一方面对提高效益、尽快收回投资具有现实意义。另外,南美及其以外市场存在多个类似项目,利用形成的技术可以进一步扩大CNODC海外其它潜在领域。为了更加客观真实地认识油藏地质特征,预测相对优质储层的空间展布和剩余油的分布规律,制定合理开发方案以提高采收率,为高效合理的开发油藏提供理论依据、研究方法和技术支持,因此开展储层特征和三维地质建模研究有着重要的实际意义。本文以秘鲁B1-AB区Capahuari Sur油田的地质背景为出发点,以地质学、沉积学、测井地质学等理论为基础,进行多学科综合研究,应用地质、测井、测试、分析化验以及开发动态等多种资料对研究区内储层地质特征进行深入剖析。在前人工作的基础上,通过“旋回对比,分级控制”进行地层精细划分与对比,建立准确空间地层格架;结合钻井取心资料和相应的测井资料,对各沉积微相特征进行分析,依据测井曲线对各井段沉积微相进行划分,在纵向和横向上进行对比,识别出研究区目的层段的沉积体系类型,并确立其沉积微相时空演化和空间展布格架;进行井位落实、井深校斜、结合三维地震资料处理解释的构造图弄清小层微构造特征;在“四性”关系研究的基础上,建立了储层参数解释模型,利用强天然水驱条件下水淹层的识别技术和隔夹层识别技术,对油区内32口井进行了单井测井解释及多井测井评价;利用测井解释成果,在小层沉积微相控制下,详细描述了储层物性分布规律、砂体展布规律以及储层非均质特征;在上述工作的基础上,选择适合研究区地质特征的建模方法,建立了构造模型、相模型和相控属性模型,从而建立了能够客观反映Vivian油藏地质特征的定量化三维地质模型。更多还原

【Abstract】 Annual production capacity of Peru Block 1AB&8 currently takes the third place in CNODC international projects, increasing the research and technique support and achieving efficient development toward this field, one side has realistic significance about retrieving the investments as soon as possible; the other side can expands CNODC international other potential fields farther with skillful techniques as result of a lot of analogous projects exist in South America and other markets. to recognize the reservoir and geological character impersonally and truly, to predict relatively superior reservoir’s dimensional distribution and distribution regulation of remain oil, to frame reasonable developing plan aiming at improving recovery ratio, this provides theoretical evidences, researching methods and technological support, so researching the reservoir character and 3D geological modeling has important realistic significance.This paper mainly begins with the geological background of Peru Block 1-AB Capahuari Sur oilfield, basing on Geology, Sediments, Well logging Geology theoris and etc. multi-subjects synthetical researching, applying Geology,Well logging, DST, Test and production materials to lucubrate the reservoir’s geological character, by "cycle strata correlation, different level to control"to fine contrast and subdivide layers on the basis of former exports’ work, establishing accurate stratum pattern; combining with drilling materials and corresponding well logging data, analysising every sedimental micro-facies, mark the sedimental micro-facies types by well logging curves, contrasting at the vertical and horizontal directions, identifying the sedimental type of target zone in this oilfield, establishing the sedimental micro-facies dimensional pattern; specifying the well location, making slant well path to vertical well path, drawing structural map combining with 3D seismic structural map, describing the micro-characters of the layer top structure.on the basis of "four kind of properties", construct the predicted parameter model, adopting waterflooding identification technology at water driving situation and barrier identification technology, finishing 32 wells single-well well logging interpretation and multi-well evaluation; adopting well logging interpretation result, under the control of layer sedimental micro-facies, particularly describing the reservoir distribution regulation, sandstone distribution regulation and reservoir inhomogeneous properties; on the basis of above researchment, choosing geological modeling method that fit for the oilfield, founding the construct model, facis model and property model that is under the control of facies, so establishing digital 3D geological model that can reflect the geological character of Vivian reservoir.更多还原
