提高油井采收率的一个重要措施是降低油井流动压力,稳定地层压力,提高生产压差。机械采油是一项主要工艺,把井底压力降低到最低值。对深井来说,这项工作是很困难的。10多年来,水力喷射系成功地用于深井开采原油,它可用于沉没度低于10％的油井。在很多情况下,水力喷射系开采井底压力低的油井是一种合理的办法。本文介绍了水力喷射泵的工作原理、性能,并通过一系列试验数据和例子,对水力喷射泵生产系统性能和气蚀极限的计算、选用提出了计算公式和理论分析。大量的实验数据证明,喷射泵的实际应用更为广泛。
An important measure to improve oil recovery is to reduce the pressure of well flow, stabilize formation pressure and increase production pressure. Mechanical recovery is a major process that minimizes bottom hole pressure. For Sham Tseng, this job is very difficult. For more than 10 years, the hydro-jet system has been successfully used for deep-well production of crude oil, which can be used in wells with submergence below 10%. In many cases, hydraulics systems are a reasonable solution for producing wells with low downhole pressures. This paper introduces the working principle and performance of hydraulic jet pump, and through a series of test data and examples, puts forward the calculation formula and theoretical analysis on the calculation and selection of the hydraulic jet pump production system performance and cavitation limit. A large number of experimental data show that the practical application of jet pump more widely.
