红岗油田复合驱先导性矿场试验

红岗油田目前的注采井网和注水方式已基本上满足了油田开发的需要,依靠常规技术提高采收率的难度越来越大,有必要探索出一种适合红岗油田实际情况的三次采油方法。经过室内研究和矿场试验证实:在红岗油田进行复合驱是可行的。矿场试验情况表明:三元复合驱技术是适合于红岗油田萨尔图油层的,尤其对剩余油饱和度较大、非特高含水井的效果非常显著。另外在国内首次把复合驱技术应用于注采井距大的反十三井网中,为红岗油田稳产高产提供了一条新的途径。

ASP FLOODING PILOT TEST IN HONGGANG OILFIELD

It is more and more difficult to enhance oil recovery in Honggang oilfield through conventional technology based on the existing well pattern and configuration. So it is increasingly necessary to seek for a suitable tertiary oil recovery method to improve ultimate recovery. The lab experiments and oilfield pilot test show that ASP flooding is most practical in Hong Gang oilfield. The pilot test also indicates that the ASP flooding effect is most remarkable in high remaining oil saturation and/or low watercut reservoir. It is the first time for the ASP technology to be applied to the sparse reverse 13-point well pattern, which is another way to maintain and even to enhance the oil rate of Honggang oilfield.
