摘　　要：川中莲池大安寨油藏具有低孔、低渗和非均质性特征。开采难度大,一次采收率低。在室内实验研 究的基础上实施了渗吸注水开发,取得了一定的效果,既补充了地层能量又增加了产量。同时形成了一套切合川 中实际的注水配套工艺技术、动态监测技术和水处理及监测技术。为川中下一步扩大在其桂花和公山庙油田的注 水开发提供了宝贵的经验。The Daanzhai oil reservoir in Lianchi oilfield of centre Sichuan has the features of low - porosity, low -permeability and heterogeneity. Its difficult to develop the reservoir was high and the first recovery factor was low. Based on the indoor experiments, the imbibition waterflooding method was used in site and definite effect was acquired which both supplemented formation energy and increased production rate. At the same time, a set of waterflooding matching techniques, dynamic monitor technique and water treatment & supervising technique, which are suited for centre Sichuan oil - gas field, were formed. It provides experiences for next waterflooding development in Guihua and Gongshan-miao oilfields in Sichuan.
