【摘要】 本论文针对双河油田Ⅶ下单元非均质油藏的地质特点和开发现状,综合应用各种勘探开发资料,以石油地质学、现代沉积学、储层地质学、开发地质学等学科理论为指导,运用高分辨率层序地层学等现代油藏描述技术和方法,以计算机技术为手段,对双河油田Ⅶ下单元油藏进行了精细描述和剩余油预测,为下一步的开发提供有利的理论指导。本研究运用高分辨率层序地层学的原理和方法,从油田生产的实际需要开发,将双河油田Ⅶ下单元的14个小层,重新划分为31个;在综合研究各种储层宏观和微观非均质性参数对储层质量影响的基础上,开展了储层多参数综合评价,对Ⅶ下单元的隔夹层进行研究,绘制了各小层的平面分布图,并对Ⅶ下单元的31个流动单元划分为4种类型,在平面上画出了所有小层的评价图。研究表明,双河油田Ⅶ下单元储层以严重非均质性为主,隔层分布受扇三角洲前缘微相控制,流动单元以G类流动单元为主。在前人研究的基础上,通过沉积背景和沉积特征分析,进行了储层沉积微相研究,认为该区为扇三角洲沉积体系。主要的沉积微相为扇三角洲前缘相,绘制了研究区主力单元的沉积微相平面图,并对相控的储层物性做了分析研究,认为微相发育的期次和规模决定了储层物性平面上的分布规律,控制了流体的宏观运动。在综合研究各种储层特征和沉积微相的基础上,借助Petrel软件,对研究区做了油藏精细描述,分别建立了储层模型、构造模型和属性模型。利用数值模拟方法,确定剩余油饱和度的分布规律,认为剩余油主要分布在构造高点、断层边部及储层物性相对较差的部位。更多还原

【Abstract】 This thesis focus on heterogeneous reservoir geological characteristics and development situation, applying comprehensive information on exploration and development, basing on oil geology, modern sedimentology, reservoir geology, using modern reservoir description techniques and computer technology, to do detailed description of basing onⅦunit in4 Shanghe oil field, providing a theoretical guidance for the next phase of development.Using the principles and methods of high-resolution sequence stratigraphy of research area, we divided basing onⅦunit 14 sand layers into 31 sand layers. In a comprehensive study of various macro-and micro-heterogeneous reservoir parameters on the basis of the reservoir quality, we launched a comprehensive evaluation to determine the evaluation criteria. The reservoir quality in 2+3 was divided into three types. The research shows that distribution of interlay and insulating layer is controlled by sedimentary microfacies. The developmental stages and the size of the sedimentary microfacies determine the plane and the vertical distribution of interlay and insulating layer. Generally, the distribution of interlay and insulating layer is relatively stable, controls the macroscopic movement of fluid.Established a microtectonics model gradually get to the regional distribution and growth of small faults in a small micro structure of the distribution. Based on sediment deposition background and sedimentary characteristics, the depositional facies of the reservoir is the fan delta-front facies. The paper researched the plane of sediment microfacies and reservoir property. We conclude the development stages and the size of the sedimentary microfacies determine the rule of the plane and control the movement of fluid.In a comprehensive study of various macro-and micro-heterogeneous reservoir parameters on the basis of the reservoir quality, we makes reservoir refined description by PETREL, including reservoir model, tectonic model and physical model. With the numerical simulation method, we elicit the distribution rules of remaining oil saturation, where is the top of structure,the side of faults and poor reservoir property.更多还原
