摘要
埕岛油田位于渤海湾南部极浅海海域,其主要产油层系是馆陶组.在对馆陶组油藏特征和初期开发方案适应性进行分析和评价的基础上,借助于油藏数值模拟,对影响埕岛油田开发效果的关键因素作了分析,提出了合理细分优化分注井段、采用变注采比分层注水方式、局部井网完善、动用Ng1+2油层组、调剖堵水、合理优化提高采油速度等稳产措施.
Chengdao oilfield lies in the extreme shallow sea area of the southern Bohai Bay, and its main production series are in Guantao Formation. Based on analyses of the Guantao reservoir features and the adaptability of primary development plan and with the help of numerical simulation of reservoir, the key factors to effective development of Chengdao oilfield are analyzed, and a series of stable production measures are proposed, including reasonable subdivision and optimization of separate water injection intervals, zonal injection on the variable injection_production ratio, local well pattern improvement in old area, exploitation of the layers 'Ng1+2', profile control and water plugging and reasonable optimization and improvement of oil production rate.
