摘　　要：延长油田志丹采油厂某区块由于地质、动态开发参数等综合影响,使注水井单向突进特别明显,因而波及效率低,采收率低,开发效果差。为改善开发现状,开展预交联颗粒-凝胶复合调驱技术,通过室内填砂管模拟实验,优选了注入段塞顺序、段塞尺寸用量、注入时机等工艺参数,结果表明,采用优选出的工艺参数可获得较好开采效果。Due to the comprehensive influence of geological reasons and dynamic development parameters in a block of Zhidan oil production plant in Yanchang oil field,the unidirectional breakthrough of water injection wells is particularly obvious with low sweep efficiency,low recovery and poor development effect.In order to improve the development status,the pre crosslinking particle gel composite flooding technology was developed.Through the indoor sand filling pipe simulation experiment,the parameters of injection slug sequence,slug size and injection timing were optimized,and the results showed that the optimized process parameters could be used to achieve better mining results.
