摘要: 洲城油田于1995年投入注水开发,取得了较好的水驱开发效果。为了进一步提高水驱效率及油藏最终采收率,开展了WXS表面活性剂可行性研究。针对洲城油田的油藏条件,对WXS表面活性剂进行了性能评价和驱油效果实验,在此基础上优化出了单井试验方案,并进行了矿场试验。结果表明,WXS表面活性剂对洲城油田提高采收率具有较好适应性。

Abstract: Since Zhoucheng oil field developing by waterflooding in 1995,it has acquired better effect. In order to improve waterflooding efficiency and ultimate reservoir recovery, we have developed feasible study of surfactant WXS. Aiming at reservoir condition of Zhoucheng oil field, the experiment of performance evaluation and oil displacement efficiency for WXS surfactant has been conducted. Then the optimized project of individual well test has been obtained, and the field test has been carried out. Results show that WXS surfactant have a better adaptability for enhancing recovery of Zhoucheng oil field.

Key words: enhanced oil recovery, water drive, field test, efficiency appraise, Zhoucheng oil field
