锦45块重水淹区于1984年开始试采,经历了常规干抽、吞吐试采和大规模蒸汽吞吐开发过程.区块边底水较为活跃,能量充足,经历近30年开发,区块采出程度较高,平面及纵向加密、调整已达极限,边底水侵入严重,生产井平均回采水率高,产量递减幅度逐年增加,开发中暴露出一系列问题,借鉴先导试验区吞吐转驱经验,应用Peterl软件建立区块地质模型,合理设置边底水,CMG数模软件进行历史拟合以及转驱方案预测,分析水淹区转驱特点,为重水淹区转蒸汽驱提供理论指导和依据.
Jin 45 heavy flooded areas began trial production in 1984 and experienced conventional dry pumping, throughput test, and large-scale steam huff and puff development processes. The edge and bottom water in the block is relatively active and energetic. After nearly 30 years of development, A higher degree of out-level, vertical and horizontal encryption, the adjustment has reached the limit, the bottom water at the end of serious water intrusion, the average production water recovery rate is high, the declining rate of production increased year by year, the development revealed a series of problems, learn from pilot test area throughput Based on the experience, using Peterl software to establish the block geologic model, setting the bottom water rationally, using the CMG software to make the history fitting and the rewinding scheme prediction, analyzing the characters of reloading in the flooded area, providing theoretical guidance for the steam flooding in the heavy flooded area, in accordance with.
