朝阳沟油田试验区扶余油层具有低渗、低产特征.采用砂岩油藏黑油模拟器,应用数值模拟方法研究剩余油分布特征,进行综合调整方案动态预测.结果表明:试验区北块剩余油分布较多,是今后调整挖潜的主要地区.有效注水方式为线性注水.综合调整措施以周期注水为主,同时,可以考虑早期分层注水、堵水以及不均匀加密等措施.分层注水应该早进行.严重水淹油井转注有一定的增产效果,但投产费用增大.
Fuyu Oilfield in Chaoyanggou Oilfield has low permeability and low yield characteristics. The sand oil reservoir black oil simulator was used to study the remaining oil distribution characteristics by numerical simulation method and to predict the comprehensive adjustment scheme dynamically. The results show that there is more residual oil in the North Block of the experimental area, which is the main area for potential adjustment in the future. Effective water injection method is linear water injection. Integrated adjustment measures to the main cycle of water, at the same time, you can consider the early stratified water, water and uneven encryption and other measures. Stratified water injection should be carried out early. Serious flooded wells have a certain amount of stimulation effect, but the cost of production increases.
