摘要
为提高孤南 1 31断块油藏的采收率 ,在加强油藏精细研究、深化油藏认识、搞清剩余油分布规律的基础上 ,通过应用复合解堵工艺、水力割缝技术、完善注采井网、优化生产参数等进行调整挖潜 .经矿场实验后 ,水驱开发效果得到了明显改善 ,采收率由 2 4 .8%提高到 2 9.0 % .
In order to increase the recovery factor of Gunan 131 fault block reservoir, some work, such as fine research of reservoir, understanding remaining oil distribution, is done. Based on these, some measures are introduced by which the potentiality of the remaining oil of the fault block reservoir is further tapped. They are combination plug removing technology, hydraulic cutting fracture technique, perfecting injection production pattern, optimizing production parameters etc. Field tests show that the measures obviously improve the result of water flooding, the recovery factor of the fault block reservoir is increased from 24.8% to 29.0%. The successful experience obtained from the development of the reservoir can be used for reference in the later development of similar reservoirs.
