南七-杏一区东部块从2011年11月开始注聚,开发到现在整个生产过程中,平均回压达到0.76MPa,甚至个别单井峰值回压达到4.3MPa,油井高回压这一问题成为了困扰整个区块生产安全平稳运行主要矛盾,由它已经引起了产量下降,检泵井次增加,生产成本增加等一系连锁反映,本文浅析了南七-杏一区东部高回压产生的原因及对油井的影响,并对目前运用的几种降压措施进行了简单评价。
South seven - Xingyi District Eastern block from November 2011 began to gather, development until now the entire production process, the average back pressure reached 0.76MPa, and even individual single-well peak back pressure reached 4.3MPa, the problem of high back pressure wells Has become the main contradiction plagued the entire block safe and stable operation of the production of the main contradictions, it has led to a decline in production, check the pump well-order increase in production costs to increase a chain reaction, this article analyzes the South seven - apricot area east back pressure The causes and the impact on the well, and the current use of several measures to reduce the pressure of a simple evaluation.
