摘要
SAGD(蒸汽辅助重力泄油)技术是一种开发超稠油经济有效方式,应用SAGD技术能够大幅提高油藏采收率,对油田的长远发展具有十分重要的意义。SAGD开发主要有两种布井方式,直-SAGD与双水平SAGD。实验以杜84块馆陶组油藏参数,流体性质为基础,采用高温高压三维比例物理模型来描述超稠油油藏直井蒸汽吞吐后转蒸汽辅助重力泄油的开发过程,认识直井与水平井SAGD和双水平井SAGD开发过程中蒸汽腔变化,各生产阶段特征和开采机理,预测油藏采收率和开发动态及生产效果。
SAGD(steam assistance gravity drive)technology is an economical and effective way to develop superheavy oil. The application of SAGD technology can greatly improve reservoir recovery, which is of great significance to the long-term development of oil field. In this experiment, Du 84 block group VI oil reservoir parameters, fluid properties as the foundation, high temperature and high pressure 3D scaled physical model is used todescribe the development process of super heavy oil reservoir steam stimulation after steam assisted gravity drainage, to understand the characteristics of each stage of production and its mechanism and the steam chamberchange of vertical and horizontal wells SAGD and double horizontal wells SAGD in the development process, finally to predict the rate of reservoir recovery and effect of dynamic development and production.
