摘要
应用油藏数值模拟技术考察底水油藏中油水分离器下入生产井后的生产状况,观察油井含水率的改变。同时考虑到注入层对生产层的干扰问题,模拟计算了打隔板下油水分离器的生产状况,考察其防止注入层与产出层窜层的效果。模拟结果表明厚层底水同层均质油藏的开采可以采用同井注采油水分离技术,此时注水对生产层的干扰是微弱的,并未导致恶性水淹;高含水期下入油水分离器开采时,打隔板控制窜层效果并不明显。
Numerical simulation method was adopted to investigate oil well production performance and the transition of water cut in bottom water drive reservoirs using Downhole Oil-water Separation (DOWS) Technology. The effect of baffles on avoiding the interference, even breakthrough, between injection zone and production zone is calculated. The result shows that DOWS Technology is applicable in thick bottom water drive homogeneous reservoirs, and the injection interfere with the production zone faintly and no malignant water flooding occur. Baffles do not have obvious effect on controlling the interference between injection and production zone in high water cut wells with DOWS.
