西峰油田提高采收率措施分析

Measure Analysis of Enhancing Oil Recovery in Xifeng Oil Field

提高采收率是油田"稳产和可持续"发展的关键,西峰油田在侏罗系油藏研究、试验起步较早,取得了一些经验与成果,为油田后期提高采收率奠定了基础。本文结合西峰油田三叠系油藏特低渗裂缝油藏的特点,以及随着开发时间的延长,诸多矛盾不断涌现,储量损失逐年加大的实际,借鉴侏罗系油藏提高采收率的研究与经验,对现有的提高采收率技术进行系统分析,评价油田近几年提高采收率技术在西峰油田适应性,提出了该油田提高采收率应努力的方向,为提高西峰油田的最终采收率具有重要意义。

To enhance oil recovery （EOR） was the key of development for oil field to stable production and be able to continue. The study and experiment was earlier for Jurassic reservoir in Xifeng oil field, and some experience and a- chievement were obtained, which was the base of EOR in later period. A system analysis on enhanced recovery technology was carried out which based on the low permeability trait of the oil deposit of Xifeng oil field and the enhanced recovery re- search and experience of Jurassic system oil deposit. The adaptability of the enhanced recovery technology used in Xifeng oil field was evaluated and the development trend of the oil field to enhance recovery was proposed which had important significance to the final recovery efficiency of Xifeng oil field.
