【摘要】：中區(qū)西部高臺子區(qū)塊位于薩爾圖油田中部,加密井于2009年投入開發(fā),由于區(qū)塊加密井開發(fā)的目的油層較多、油層物性差且臨近高含水層,該區(qū)塊基礎(chǔ)含水高于預(yù)期含水,含水上升速度較快,短期內(nèi)就進入特高含水期開采階段。為了進一步延長高臺子區(qū)塊穩(wěn)產(chǎn)期,實現(xiàn)“穩(wěn)油控水”的目的,必須進一步對油層進行精細(xì)地質(zhì)研究,弄清剩余油分布特征,適時采取措施挖潛方法。中區(qū)西部高臺子加密井網(wǎng)已進入特高含水期開采,注入水低效無效循環(huán)嚴(yán)重。通過動、靜態(tài)資料綜合分析,尋找剩余油的富集區(qū)。針對不同儲層沉積微相及單砂體的動用、水淹狀況,優(yōu)化各項措施。本文介紹了中區(qū)西部高臺子的地質(zhì)特征和開發(fā)概況,為進一步提高采收率,對該區(qū)塊油藏進行精細(xì)描述,介紹了沉積單元的劃分、沉積類型和特征以及儲層非均質(zhì)性特征分析;通過數(shù)值模擬計算,得到了中區(qū)西部平面剩余油飽和度分布圖,并通過數(shù)值模擬結(jié)果數(shù)據(jù),統(tǒng)計分析了中區(qū)西部剩余油分布規(guī)律,總結(jié)出了中區(qū)西部平面剩余油的分布特征和規(guī)律。針對區(qū)塊存在的問題和剩余油潛力分布,制定了調(diào)整思路,確定了精細(xì)挖潛的工作安排,進行了效果預(yù)測和效益評價�？偨Y(jié)出開采過程的實踐認(rèn)識,解決影響因素,摸清單井潛力,大力推進精細(xì)分析,精細(xì)挖潛,精細(xì)測調(diào),通過油水井的綜合調(diào)整,使開發(fā)效果達到極限,為水驅(qū)特高含水期的“控水挖潛”工作提供一定的理論和實踐依據(jù)。
[Abstract]:Gaotaizi block in the west of Central region is located in the middle of Saltu Oilfield, and the infill well was put into development in 2009. Due to the large number of target reservoirs, poor physical properties of reservoir and close to high aquifer, the basic water cut of this block is higher than the expected water cut.The speed of water-cut rise is fast, and it will enter the stage of very high water cut in the short term.In order to further prolong the stable production period of Gaotaizi block and realize the purpose of "stabilizing oil and controlling water", it is necessary to further study the fine geology of the reservoir, make clear the distribution characteristics of remaining oil, and take appropriate measures to tap the potential.The pattern of Gaotaizi infill well in the west of central district has entered the stage of super high water cut, and the inefficient cycle of injection water is serious.Through comprehensive analysis of dynamic and static data, a rich area of remaining oil is found.According to the production of sedimentary microfacies and single sand body in different reservoirs, the measures are optimized.In this paper, the geological characteristics and development situation of Gaotaizi in the western part of the central area are introduced. In order to further improve the oil recovery, the reservoir in this block is described in detail, and the division of sedimentary units, sedimentary types and characteristics, and the analysis of reservoir heterogeneity characteristics are introduced.Through the numerical simulation, the distribution map of the remaining oil saturation in the western part of the central region is obtained, and the distribution law of the remaining oil in the western part of the central region is statistically analyzed through the data of the numerical simulation results.The distribution characteristics and laws of the remaining oil in the western part of the central region are summarized.In view of the problems existing in the block and the potential distribution of remaining oil, the adjustment thought was made, the working arrangement of fine tapping potential was determined, and the effect prediction and benefit evaluation were carried out.This paper summarizes the practical understanding of the production process, solves the influence factors, finds out the potential of the single well, vigorously promotes the fine analysis, the fine tapping of potential, the fine survey and adjustment, and makes the development effect reach the limit through the comprehensive adjustment of the oil and water wells.It provides a certain theoretical and practical basis for "controlling water potential" in the period of water flooding with extra high water cut.
