摘要
随着我国大部分油藏的持续开采,稠油油藏所占比例增大,开发难度大于常规油藏。针对如何提高稠油油藏采收率这一重要课题,概述了目前稠油油藏开发采用的热采技术(热水驱、蒸汽驱、蒸汽辅助重力泄油和蒸汽吞吐)和冷采技术(表面活性剂驱、碱驱、聚合物驱、复合驱和微生物驱),浅析了其作用原理,结合现有矿场试验资料分析了各技术的优点及存在的问题,并对未来的发展方向提出了建议。
With the continuous exploitation of most of the reservoirs in China,the proportion of heavy oil reservoirs increased, whose development was more difficult than conventional reservoirs. Aiming at the important issue of how to improve the recovery of heavy oil reservoirs,the thermal recovery technology,such as hot water flooding,steam flooding,SAGD and huff and puff, and cold production technology,such as surfactant flooding,alkaline flooding,polymer flooding,composite flooding and microbial flooding,used in the development of heavy oil reservoirs were summarized,meanwhile their principles of action were analyzed. The advantages and problems of each technology were analyzed combining the existing mine test data,and development directions of improving heavy oil recovery technology were proposed.
