摘要
超稠油粘度大 ,流动性差 ,开采难度较大 ,尤其是薄互层油藏 ,其开采难度更大 ,开采的关键问题就是注采参数和工艺的合理选择 ,以尽可能发挥油层最大潜能 ,达到最佳开采效果。辽河油田根据该类油藏的特点 ,经过室内优化和现场试验 ,建立并形成了薄互层超稠油油藏试采的配套工艺技术 。
Because of the viscosity of super-viscous oil is high, The flow property is bad . it is difficult to recovery the oil, especially the thin alternating layers reservoir. So it is important to choose the parameters of injection-production and technologies. Thus we can make full use of the reservoir as possible. Matching technologies have been developed about the reservoir by Liaohe oilfield . on the base of its performance, these technologies are all verified by indoor-optimization and field experiments, all these technologies and experiences may be exchanged for spread recovery of the reservoir.
