【摘要】：曙4—7—14块位于沟海铁路以西、绕阳河以南的杜家台地区。构造上处于辽河断陷盆地西部凹陷西斜坡中段、曙光油田曙四区的东南部,东与曙光古潜山相邻,主要开发层系为下第三系沙河街组四段上部的杜家台油层。油层分布受构造、岩性影响,为岩性构造油藏,该块杜家台油层无边底水发育。曙4—7—14块长期水驱开发,储层非均质性加剧,在目前注水方式下,注水波及体积难以进一步提高,难以大幅度提高采收率。为此,在本油块地质体精细刻画的基础上优选试验区,开展深部调驱试验,对辽河油田普通稠油油藏提高采收率具有重要的指导意义。论文前言首先提出主要研究内容、提交的主要成果、所取得的认识及成果。正文部分对油田概况、油藏地址特征研究、注水开发效果评价、可行性分析、油藏工程方案设计、调驱指标预测及经济评价、动态检测方案及实施要求进行了详细的描述。涉及多个学科理论知识,利用表格、图片、文字进行研究阐述,论证曙4—7—14块油藏进行调驱后可提高油藏采收率可行,充分挖掘石油开采资源研,采取正确的开采方式,进而达到研究目的。本课题所研究的方法适用于辽河油田老油区复杂环境的开采,具有重要积极的意义,对于未来老区块开采具有重要的借鉴和指导价值。
[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.
