【摘要】：本文通過從構(gòu)造、儲(chǔ)層、沉積及油藏分布等方面入手,對(duì)黃20井區(qū)油藏動(dòng)靜態(tài)綜合研究,通過對(duì)地質(zhì)體特征進(jìn)行整體細(xì)致、深入的刻畫,進(jìn)一步搞清和細(xì)化油藏的各項(xiàng)地質(zhì)和開發(fā)屬性,建立可靠的油藏地質(zhì)模型和剩余油分布規(guī)律,并確定油田下一步挖潛穩(wěn)產(chǎn)的潛力,為油藏開發(fā)調(diào)整提供優(yōu)化方案。該研究是以鉆井資料為主,結(jié)合三維地震資料,進(jìn)行全區(qū)地層統(tǒng)層對(duì)比和各研究區(qū)塊小層的劃分對(duì)比研究;在地層劃分對(duì)比研究基礎(chǔ)上,進(jìn)行層序地層學(xué)研究,建立等時(shí)性地層格架研究;利用高分辯率的地震資料重新對(duì)該區(qū)斷裂系統(tǒng)進(jìn)行精細(xì)解釋;以小層為單元進(jìn)行沉積微相研究;結(jié)合工區(qū)面積大,構(gòu)造復(fù)雜,含油氣層系多,區(qū)域背景處于斜坡狀態(tài)的特點(diǎn),抓大突小。首先進(jìn)行地層、構(gòu)造、儲(chǔ)層宏觀分布和不同沉積體系研究,全區(qū)整體解剖,宏觀控制,抓住以大層的區(qū)域統(tǒng)層、構(gòu)造精細(xì)解釋和儲(chǔ)層分布為主線,建立油田級(jí)油藏主體框架;并以斷塊區(qū)為油藏描述的落腳點(diǎn),細(xì)分、細(xì)作,這樣主次分明,重點(diǎn)突出。通過以上工作將沙一段劃分為上、中、下三個(gè)亞段15個(gè)砂巖組33個(gè)小層,沙三一段劃分為三個(gè)油層組19個(gè)小層。重新落實(shí)了黃20井區(qū)構(gòu)造、沉積環(huán)境、儲(chǔ)層、油藏類型、剩余油分布,對(duì)井區(qū)進(jìn)行綜合調(diào)整,部署新井6口,編制了注采井別方案。
[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.
