【摘要】：本文通过从构造、储层、沉积及油藏分布等方面入手,对黄20井区油藏动静态综合研究,通过对地质体特征进行整体细致、深入的刻画,进一步搞清和细化油藏的各项地质和开发属性,建立可靠的油藏地质模型和剩余油分布规律,并确定油田下一步挖潜稳产的潜力,为油藏开发调整提供优化方案。该研究是以钻井资料为主,结合三维地震资料,进行全区地层统层对比和各研究区块小层的划分对比研究;在地层划分对比研究基础上,进行层序地层学研究,建立等时性地层格架研究;利用高分辩率的地震资料重新对该区断裂系统进行精细解释;以小层为单元进行沉积微相研究;结合工区面积大,构造复杂,含油气层系多,区域背景处于斜坡状态的特点,抓大突小。首先进行地层、构造、储层宏观分布和不同沉积体系研究,全区整体解剖,宏观控制,抓住以大层的区域统层、构造精细解释和储层分布为主线,建立油田级油藏主体框架;并以断块区为油藏描述的落脚点,细分、细作,这样主次分明,重点突出。通过以上工作将沙一段划分为上、中、下三个亚段15个砂岩组33个小层,沙三一段划分为三个油层组19个小层。重新落实了黄20井区构造、沉积环境、储层、油藏类型、剩余油分布,对井区进行综合调整,部署新井6口,编制了注采井别方案。
[Abstract]:In this paper, from the aspects of structure, reservoir, sedimentation and reservoir distribution, the dynamic and static characteristics of well Huang20 reservoir are comprehensively studied, and the characteristics of geological body are described in detail and in depth. Further understanding and refining the geological and development properties of the reservoir, establishing a reliable reservoir geological model and residual oil distribution law, and determining the potential of the oil field to tap potential and stable production in the next step, to provide an optimized scheme for reservoir development adjustment. This research is mainly based on drilling data and combined with 3D seismic data to study the stratigraphic correlation and the division and correlation of the sub-layers in each research block, and on the basis of the stratigraphic division and correlation study, the sequence stratigraphy is studied. The study of isochronous stratigraphic framework, the use of high-resolution seismic data to reinterpret the fault system in this area, the study of sedimentary microfacies with small layers as units, the large area of the work area, the complex structure, and the abundance of oil-bearing gas reservoirs, The regional background is characterized by a slope state, and the regional background is large and small. Firstly, the main frame of oilfield grade reservoir is established by studying stratum, structure, reservoir macroscopical distribution and different sedimentary system, dissecting the whole area and controlling macroscopically, taking the regional strata of large layer, fine interpretation of structure and reservoir distribution as the main line. The fault block area is regarded as the foothold of reservoir description, subdivision and fine work, so the main and secondary points are clear and the emphasis is prominent. According to the above work, the first member of Sha I is divided into upper, middle and lower three sub-member, and there are 15 sandstone formations and 33 sub-layers, and the third member is divided into three reservoirs and 19 layers. The structure, sedimentary environment, reservoir, reservoir type and remaining oil distribution of Huang20 well area have been re-implemented. The well area has been comprehensively adjusted, 6 new wells have been deployed, and the injection and production wells have been worked out.
