压裂泵是进行油井酸化和加砂两种压裂工艺以增产原油的关键设备。目前高冲次压裂泵存在的最大问题是在砂粒的作用下,泵阀和柱塞寿命较短。尽管有些国家在改善泵阀等结构及其材质和处理工艺方面做了一定的工作,相应延长了泵的使用寿命,但问题仍未彻底解决。美国哈利伯顿(Halliburton)公司针对上述问题提出了一种长冲程低冲次增压泵,可以大大延长泵阀和柱塞的寿命,同时还在很大程度上改善了系的各种工作性能,可供参考。
Fracturing pump is a key equipment for oil well acidification and sand plus two fracturing technology to increase crude oil production. At present, the biggest problem with high-pressure fracturing pumps is the short life of the valves and plungers under the action of sand. Although some countries have done some work to improve the structure of the valve and other materials and the processing technology, the service life of the pump has been correspondingly prolonged, but the problem is still not completely solved. The United States Halliburton company proposed a long-stroke low-stroke booster pump to solve the above problems, which can greatly extend the life of the pump valve and plunger, while still largely improving the Department of various work Performance, for reference.
