过去使用的圆柱形钻孔油嘴,在其额定工况下,在完成配产作用的同时要损耗50％的油压。因此,在油田进入中、高含水开采期之后,整个地面油气集输系统,将因集输能力不足而引起频繁的流程改造。本文介绍的新型油嘴,其油压损耗率只有25～30％,所以对自喷采油期较长的采用早期注水采油的油田,推广使用新型油嘴,对提高油气集输能力,延长油田稳产期,减少地面集输流程改造的工程量等,具有重要的意义。
Cylindrical bores used in the past have suffered 50% of the hydraulic load loss at the time of their assigned service. Therefore, after the oilfield enters the middle and high water cut period, the entire surface oil and gas gathering and transportation system will cause frequent process reformation due to insufficient gathering and transportation capacity. The new type of oil nozzle introduced in this paper has a hydraulic loss rate of only 25-30%. Therefore, a new type of oil nozzle is adopted for oilfields with long-term self-spraying oil recovery that use early oil-water production to promote the capacity of oil and gas gathering and transportation, prolong the stable production period, It is of great significance to reduce the amount of engineering that is needed for the reconstruction of the ground transportation project.
