提高采收率研究是各石油生产国极为重视的一项研究课题。瓦村油区经过长期开发以后,地层亏空严重,能量严重不足,严重制约了油区的有效开发,因此有必要进行提高采收率的研究。世界上最早使用的驱油方法是注水驱油,也是目前我国最常用的提高采收率方法之一。通过对该区块的研究提出了北部主要通过油井转注污水,南部实行打加密井的具体开发实施方案。
Research on enhanced oil recovery is a subject of great importance to all oil producing countries. After the long-term development of the Wacun oil zone, the stratigraphic deficit is serious and the energy is seriously insufficient, which has seriously hampered the effective development of the oil zone. Therefore, it is necessary to conduct research on enhanced oil recovery. The earliest oil displacement method used in the world is water flooding, which is also one of the most commonly used methods to enhance oil recovery in China. Based on the study of this block, it is proposed that the development of sewage in the north mainly through oil wells and the practice of tight wells in the south.
