空心抽油杆采油技术的研究及应用

Hollow Pumping Rod Production technique Its Application in Zhongyuan Oilfield

受地质特点的制约 ,中原油田引进了空心杆采油技术。文中介绍了它的原理、管柱结构、应用条件和现场应用情况。空心杆采油技术与传统采油方式相比 ,具有冲程损失小 ,不需油管 ,泵效高 ,成本低等特点。通过在中原油田 7口井应用 。

By restricting geoglogical features of Zhongyuan Oilfield.The hollow pumping rod production technique was introduced into the oilfield comparing with usual production technique,the technique has some characteristics,such as small stroke loss,no tubing,high pump efficiency and low cost.the Paper introduces theory,pipe string construction,application condition and actual application,by appling in 7 oil wells in Zhongyuan Oilfield,better effect got it.
