摘要
对古城油田B125断块油藏地质和开发动态进行了分析与研究,结合该块注热水区块的油藏特性,进行了表面活性剂驱提高采收率技术室内试验。通过表面活性剂与油田水的配伍性研究、乳化性试验和表、界面张力的测定,筛选出适合本区块的表面活性剂,并进行了室内驱油试验和先导试验方案设计。结果表明,用表面活性剂HPS-3B、HPS-3C能大幅度提高普通稠油的采收率,具有较好的经济效益。
Abstract
Analyzed geology, develop dynamics and reservoir characteristics of hot water injection block of B125 block on Gucheng oilfield, laboratory experiment was developed by surface acting agent in order to improving recovery ratio. Based on the research of compatibility of surface acting agent with field water, experiment of emulsify and testing of surface and interfacial tension, select surface acting agent which adequate for B125 block, oil disperse experiment and precursor testing scheme were designed. Results shows that surface acting agent HPS-3B, HPS-3C can obviously improve heavy oil recovery ratio.
