摘要
依据文 1 84断块油藏条件和原油物性特点 ,认为采用 CO2 混相驱是提高该区采收率的一种有效方法。通过对全区注水处理的历史拟合 ,设计了两种不同注入方式——单段塞注气和水气交替注入。油藏数值模拟结果表明 ,CO2 与文 1 84断块地层流体在目前压力下可以混相 。
Based on the reservoir conditions and physical properties of crude oil in block Wen 184, CO 2 miscible displacement is thought to be an effective way to enhance the oil recovery in the block Through the history matching of water injection of the whole region, two injection modes of single slug and water gas alternating injections are designed for gas injection The simulation result demonstrates that CO 2 can be miscible with formation fluid in block Wen 184 under the present pressure The amplitude of enhanced oil recovery of water gas alternating injection is higher than that of gas injection by single slug
