杜玛兹油田是最早采用边外注水保持地层压力方法开发的油田之一,目前已进入开发晚期阶段,所以在开发过程中地层原油性质所发生的变化具有重要意义.
The Dumazi oilfield is one of the earliest oilfields developed by the method of maintaining formation pressure by injecting water outside the reservoir. Currently, it has entered the late stage of development. Therefore, it is of great significance to make changes in the nature of the crude oil during the development process.
