玻璃钢杆抽油井深井泵防冲距的理论探讨及计算

Research on Calculating Anticollision Spacing of Deep-Well Pump in Pumping Well Using Fiberglass Sucker Rod

国内在玻璃钢抽油杆的应用中，杆柱断脱现象比较严重，本文通过对影响玻璃钢杆抽油井深井泵防冲距各因素的分析和计算，发现目前现场设计防冲距所采用的经验公式误差太大，是造成杆柱断脱的因素之一。为解决这一问题，本文提出了一套计算防冲距的公式。

Break and dropout of rod string are very serious in the application of fiberglass sucker rod to our country. By analyzing and calculating the factors to affect the anticollision spacing of deep-well pump in pumping well using fiberglass sucker rod,the author finds that the field formulas to design anticollision spacing have great error,and is one of the factors to course break and dropout of rod string at present. This paper gives a series of formulas to calculate anticollision spacing'
