早期的油田开发技术水平较低,使超过50%的探明石油储量留在地下被废弃。随着石油勘探开发程度的加深,开采难度逐步加大,石油采收率的提高成为一个迫需解决的问题。近十年来我国三次采油技术快速发展起来,它的推广应用对提高原油采收率、稳定老油田原油产量起到了重要的作用。本文对三次采油的技术原理、三次采油新技术进行了阐述,并介绍了我国三次采油技术发展方向,旨在为各油田的三次采油采收率的提高提供借鉴。
Early oilfield development technology was low, leaving more than 50% of proved oil reserves underground abandoned. With the deepening of the degree of petroleum exploration and development, the exploitation difficulty is gradually increased, and the improvement of oil recovery rate becomes a problem that needs to be solved. In the recent ten years, the tertiary recovery technology in our country has developed rapidly. Its popularization and application have played an important role in raising the recovery rate of crude oil and stabilizing the crude oil output of the old oilfield. In this paper, the technical principle of tertiary recovery and the new technology of tertiary recovery are expounded, and the development of tertiary recovery technology in our country is introduced. The purpose of this paper is to provide reference for the tertiary recovery recovery of each oilfield.
