美国“世界石油”杂志1976年11月第186卷第6期,发表了美国贝利亨公司研制阿尔法Ⅰ型抽油机的文章,该文详细摘要(译文名:新型长冲程抽油机)已刊登于本刊1977年第2期。这种抽油机冲程长12.20米,采用50马力电动机和普通的变速箱,扭矩负荷低;由于冲程长,降低了气锁的可能性,提高抽油泵的效率,适用于低压高产量抽油井。但在采用时需要另打一口深度16.8米、直径914毫米(下入762毫米的套管)的平衡块井,并配备电动机自动转向控制系统。 从1977年2月起,这种抽油机在俄克拉荷马州经历15个月的现场考验。实践证明,与游梁式抽油机相比,有某些优越性。试验情况刊登在美国“石油工程师”杂志1978年8月号,本刊特译出,供有关同志参考。
The United States of America “World Petroleum” magazine in November 1976 No. 186, No. 6, published the United States Berliner company developed Alpha Type Ⅰ pumping unit article, the detailed abstracts (translation: the new long stroke pumping unit) has been Published in the second issue of 1977. This pumping unit has a stroke length of 12.20 meters and uses a 50-horsepower motor and an ordinary gearbox with low torque load. Due to the long stroke, it reduces the possibility of air locks and increases the efficiency of the pump, making it suitable for low-pressure and high-volume pumping wells. However, an additional balancer well depth of 16.8 meters and a diameter of 914 millimeters (762 millimeters of casing) was required for the application and was equipped with an automatic motor steering control system. As of February 1977, the pumping unit has undergone a 15-month field test in Oklahoma. Practice shows that, compared with the beam pumping unit, there are some advantages. Tests published in the United States, “Petroleum Engineers” magazine in August 1978 issue, the special translation, for the comrades for reference.
