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
