摘要
针对常规注水过程中的地层能量亏空和含水上升速度快等问题,进行间歇注水提高水驱效率研究。根据CY井区间歇注水设计和开发实践情况,结合数值模拟技术进行间歇注水参数优化。通过多种方案优选,评价注水参数对间歇注水和水驱效率的影响。
Due to some problems, such as formation depletion and fast water cut increase in conventional water flooding, we carried on the research of cyclic water flooding to improve water displacement efficiency. According to the intermittent water injection design and production practice in CY block, and combined with numerical simulation, the parameters of intermittent water injection was also optimized. Through a variety of program optimization, effects of water injection parameters on intermittent water injection and water drive efficiency was analyzed.
