【摘要】：南泥灣油區(qū)和大多數(shù)油田一樣都采用了注水保持壓力的開發(fā)方式,出現(xiàn)了油井含水上升快和高含水井,急需進(jìn)行治理和研究。因此本文對(duì)南泥灣采油廠選擇一個(gè)高含水區(qū)塊進(jìn)行注水開發(fā)效果分析的研究。本論文主要研究?jī)?nèi)容如下:1在油藏基礎(chǔ)地質(zhì)的基礎(chǔ)上,利用已有的動(dòng)靜態(tài)資料,對(duì)油藏特征做出新的認(rèn)識(shí)和評(píng)價(jià);2進(jìn)行油田開發(fā)動(dòng)態(tài)分析;3對(duì)開發(fā)效果和現(xiàn)注水開發(fā)方案進(jìn)行分析評(píng)價(jià),找出影響油井含水快速上升的因素和油田開發(fā)效果的主要問題;4合理調(diào)整注采關(guān)系,確定相應(yīng)的調(diào)整方案和治理措施,提高油田最終采收率。通過一系列的研究,油藏綜合治理方案需要完善注采井網(wǎng)、調(diào)整注采對(duì)應(yīng)關(guān)系、優(yōu)化注水技術(shù)政策和嚴(yán)格控制注入水水質(zhì)。高含水井的綜合治理對(duì)策主要有:注水調(diào)整、周期注水、堵水調(diào)剖和線狀注水。因此科學(xué)合理的評(píng)價(jià)注水開發(fā)效果,不僅對(duì)南泥灣高含水井的有效治理具有重要意義,更為進(jìn)一步搞好油藏注水開發(fā)以及提高最終采收率具有重要的意義。同時(shí),為類似南泥灣油田的其它油區(qū)的高效注水開發(fā)提供借鑒和示范作用。
[Abstract]:The Nanniwan oil area, like most oilfields, has adopted the development method of water injection maintenance pressure, and the oil wells have a rapid rise in water cut and a high water cut. Therefore, this paper studies the selection of a high water-cut block to analyze the effect of waterflooding development. The main contents of this paper are as follows: 1 on the basis of reservoir basic geology. Based on the existing static and static data, a new understanding and evaluation of reservoir characteristics are made. To find out the factors that affect the rapid rise of water cut in oil wells and the main problems of oilfield development effect: to rationally adjust the relationship between injection and production, to determine the corresponding adjustment scheme and treatment measures, and to improve the final oil recovery of the oil field. Through a series of studies, The comprehensive control plan of reservoir needs to perfect injection-production well pattern, adjust injection-production corresponding relation, optimize water injection technology policy and strictly control injected water quality. The comprehensive treatment countermeasures of high water cut well include: water injection adjustment, periodic water injection, etc. Therefore, scientific and reasonable evaluation of water injection development effect is not only of great significance to the effective treatment of high water cut wells in Nanniwan. It is of great significance to further improve the reservoir water injection development and to improve the final recovery. At the same time, it provides reference and demonstration for the development of high efficiency water injection in other oil areas similar to Nanniwan Oilfield.
