欧利坨油田是辽河盆地东部凹陷低渗油藏有效开发的典范。本文主要介绍了欧利坨油田低渗透油气藏开发主要做法,通过对油田低渗区块的岩性,油藏分布特征,储层物性特征,流体渗流特征、压力分布的分析,加上国内类似低渗油藏的有效开发经验及理论,理论联系实际制订合理了欧利坨低渗油藏的开发方案。在实施过程中,主要以加密井网、压裂、注水、制订合理的生产压差等技术手段进行开发,即时同步进行总结,效果评价,使低渗透断块油藏得到较好的开发效果,达到持续稳产。
Olichituo Oilfield is an example of effective exploitation of low-permeability reservoirs in eastern sag of Liaohe Basin. This paper mainly introduces the main practices of the development of low permeability oil and gas reservoirs in Oly Tuo Oilfield. Based on the analysis of lithology, reservoir distribution, physical property of reservoir, fluid seepage characteristics and pressure distribution of low permeability block in oilfield, The effective development of low permeability reservoirs and theory, theory and practice to formulate a reasonable Ouli Tuo low permeability reservoir development program. In the process of implementation, it mainly develops by means of technical methods such as well patterning, fracturing, water injection and formulating reasonable production pressure differential, so as to summarize and evaluate the results in real time and synchronously, so that the low permeability fractured reservoirs can obtain better development results, To achieve sustained and stable production.
