摘要: 启动压力梯度对低渗透油藏生产具有重要影响,根据现场获取岩心利用室内实验求取启动压力梯度,并绘制渗透率与启动压力梯度图。建立考虑启动压力梯度的油藏生产动态模拟数学模型,在地层平均渗透率条件下,考察不同启动压力梯度对油藏生产动态的影响,以对现场低渗透油藏开发提供指导。研究表明,随启动压力梯度增加,产液量、采出程度、无水采出程度均呈降低趋势,含水率略有上升;启动压力梯度对注采平衡具有重要影响,水井注水量随启动压力梯度增加逐渐降低。

Abstract: Threshold pressure gradient has an important influence to low permeability reservoir production. According to the site to obtain core laboratory experiments to strike threshold pressure gradient and draw permeability threshold pressure gradient plates. The dynamic simulation mathematical model of reservoir production considering threshold pressure gradient was established. The different threshold pressure gradient on the reservoir production performance was examined under the conditions of formation average permeability and provide guidance onsite low permeability reservoir development.The results show that with the threshold pressure gradient increases,liquid production, the degree of recovery, anhydrous degree of recovery have a decreasing trend and a slight increase in the moisture content. Threshold pressure gradient has an important influence on the balanced injection,the well. Water injection with threshold pressure gradient increases gradually reduced.
