【摘要】：曙4—7—14塊位于溝海鐵路以西、繞陽河以南的杜家臺地區(qū)。構(gòu)造上處于遼河斷陷盆地西部凹陷西斜坡中段、曙光油田曙四區(qū)的東南部,東與曙光古潛山相鄰,主要開發(fā)層系為下第三系沙河街組四段上部的杜家臺油層。油層分布受構(gòu)造、巖性影響,為巖性構(gòu)造油藏,該塊杜家臺油層無邊底水發(fā)育。曙4—7—14塊長期水驅(qū)開發(fā),儲層非均質(zhì)性加劇,在目前注水方式下,注水波及體積難以進一步提高,難以大幅度提高采收率。為此,在本油塊地質(zhì)體精細刻畫的基礎(chǔ)上優(yōu)選試驗區(qū),開展深部調(diào)驅(qū)試驗,對遼河油田普通稠油油藏提高采收率具有重要的指導(dǎo)意義。論文前言首先提出主要研究內(nèi)容、提交的主要成果、所取得的認識及成果。正文部分對油田概況、油藏地址特征研究、注水開發(fā)效果評價、可行性分析、油藏工程方案設(shè)計、調(diào)驅(qū)指標預(yù)測及經(jīng)濟評價、動態(tài)檢測方案及實施要求進行了詳細的描述。涉及多個學(xué)科理論知識,利用表格、圖片、文字進行研究闡述,論證曙4—7—14塊油藏進行調(diào)驅(qū)后可提高油藏采收率可行,充分挖掘石油開采資源研,采取正確的開采方式,進而達到研究目的。本課題所研究的方法適用于遼河油田老油區(qū)復(fù)雜環(huán)境的開采,具有重要積極的意義,對于未來老區(qū)塊開采具有重要的借鑒和指導(dǎo)價值。
[Abstract]:Block Shu 4-7-14 is located in the Dujiatai area west of the Gouhai Railway and south of the Shaoyang River. It is structurally located in the middle of the west slope of the western depression of the Liaohe fault depression and in the southeastern part of the Shu 4 area of Shuguang Oilfield. The east is adjacent to the Shuguang buried hill, and the main development layer is the Dujiatai oil reservoir in the upper part of the fourth member of Shahejie formation of the Lower Tertiary system. The distribution of the oil layer is affected by the structure and lithology, and it is a lithologic reservoir. The reservoir heterogeneity is aggravated because of long-term water flooding in block Shu 4-7-14. Under the current water injection mode, the sweep volume of water injection is difficult to be further improved. It is difficult to improve oil recovery by a large margin. Therefore, on the basis of fine description of the geological body in this oil block, the deep modulation flooding test is carried out by selecting the experimental area. In the foreword of this paper, the main research contents, the main results submitted, the knowledge and the results obtained are put forward, and the general situation of the oil field is also discussed in the main part of the paper, which is of great significance to improve the recovery efficiency of the ordinary heavy oil reservoirs in Liaohe Oilfield. Research on reservoir address characteristics, evaluation of waterflooding development effect, feasibility analysis, reservoir engineering scheme design, prediction of adjustment and flooding index and economic evaluation. Dynamic detection scheme and implementation requirements are described in detail, involving a number of disciplines of theoretical knowledge, using tables, pictures, text for research and elaboration. It is proved that oil recovery can be improved by adjusting and flooding in Block Shu 4-7-14, and oil recovery resources can be fully exploited, and the correct exploitation method is adopted. The method studied in this paper is suitable for the exploitation of the complex environment in the old oil area of Liaohe Oilfield, which has important positive significance, and has important reference and guiding value for the future exploitation of the old block.
