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,取得了明显效果。

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 .
