随XN区块油藏不断开发,井组高回压已成为制约油区发展的一个不容忽视的因素,井组回压升高关系着单井产能、泵效、抽油机及其井下管杆使用寿命、集输管线跑冒滴漏等一系列问题。为合理优化原油生产系统及技术系统,本文以XN区为例重点分析了回压对抽油泵泵效、油井产量、抽油机耗电量的影响,并对高回压井组制定相应对策并从而降低井口回压。
With the continuous development of XN block reservoirs, the high back pressure of well group has become a factor that can not be ignored in the development of oil area. The increase of back pressure in well group is related to the single well productivity, pump efficiency, pumping unit and its use Lifespan, gathering plumbing leakage and a series of problems. In order to reasonably optimize the crude oil production system and technical system, this paper focuses on the XN area as an example to analyze the effect of back pressure on pump efficiency, oil well production, power consumption of pumping unit and formulate corresponding countermeasures for high backhoe well group. Lower well head back pressure.
