【摘要】：目前,我国多数油田已经进入高含水或特高含水的开采后期,常规的堵水调剖技术已不能满足油田生产需求,深部调驱技术是近几年发展起来的一项旨在改善油田注水开发效果的技术,在改善高含水油藏水驱开发方面获得了显著效果。辽河油田根据欢26断块油藏非均质严重、注水利用率低、注水效果逐年变差的特点,有针对性的开展了深部调驱技术。本论文将通过系统分析国内外调剖堵水技术的现状及存在问题,结合该区块开发现状及存在的主要问题,系统地开展区域沉积特征、孔隙度特征、流体性质分析、油藏条件分析等精细地质研究,认真收集欢26块油藏压力、水驱储量控制程度、水驱动用程度、注水利用率等相关数据,重点对凝胶体系、体膨颗粒类以及驱油体系等开展室内静态和动态性能指标筛选和评价研究,通过一系列试验给出适合于欢26块油藏特点的调驱体系配方和注入方式,建立“封、调驱、洗”设计理念,利用复合凝胶体系封堵优势通道,利用可动凝胶调驱,注入地层深部,实现液流转向,改善吸水剖面,提高注入水波及体积,最终提高水驱采收率,为老区持续稳产发挥积极的作用。
[Abstract]:At present, most oil fields in China have entered the late stage of production with high water cut or extra high water cut, and the conventional water plugging and profile control technology can no longer meet the production needs of oil fields. Deep water flooding is a technology developed in recent years to improve the water flooding development in oil fields. It has achieved remarkable results in improving water drive development in high water cut reservoirs. According to the characteristics of serious heterogeneity of Huan26 fault block reservoir, low water injection utilization rate and poor water injection effect year by year, Liaohe Oilfield has developed the deep adjustment and flooding technology. This paper will systematically analyze the present situation and existing problems of profile control and water shutoff technology at home and abroad, combining with the current situation and main problems of the development of the block, systematically carry out the analysis of regional sedimentary characteristics, porosity characteristics and fluid properties. Fine geological research, such as reservoir condition analysis, and serious collection of relevant data such as reservoir pressure, water drive reserve control degree, water drive use degree, water injection utilization ratio, etc., in block Huan 26, with emphasis on the gel system, The static and dynamic performance index screening and evaluation research were carried out in laboratory, such as bulky particles and oil displacement system. Through a series of tests, the formula and injection mode of oil displacement system suitable for Huan 26 reservoir were given, and the "sealing, adjusting flooding" was established. "washing" design concept, using composite gel system to block the dominant channel, using movable gel to adjust and drive, injecting deep layer, realizing liquid flow turn, improving water absorption profile, increasing injection water wave and volume, and finally increasing water drive recovery, To play a positive role in maintaining stable production in the old area.
