有杆抽油泵在14,500英尺的成功使用

有杆抽油泵在14,500英尺的成功使用(中文5600字,英文3000字)
摘要
在1982.9.21，41X24D井在怀俄明州的粉状河盆地的领域变成了世界最深的有杆泵抽油井。在这个装置之前，最大的经验深度被限制到大约11,500英尺[3505m]左右。它的有杆泵，被安装在14，500英尺[4420m]，自从1982年以来一直成功地运转。这个有杆泵举升系统代替了自从在1966年安装完成以后一直被使用的水力举升井。操作使用中频繁的保养带来的停工期造成了较差的经济效益是水力举升泵的使用情况变化。泵的维护和操作费用比以前增加了加倍，而且联合的停工时间命令了变化。生产领班保持的记录文件记录了41X24D井在早先12个月的操作期间14个水力举升泵的失败。这些失败的费用接近了$25,000。在年度井况的回顾中，水力举升泵被建议转换成有杆泵举升来改善情形。
在洛矶山脉我们的深井有杆泵的使用经验已经被证明是较好的。这个装置的使用理论正在进行深入讨论。

Successful Rod Pumping at 14,500 Feet

Summary.
Well 41X24D of the Reno field in Wyoming's Powder River basin became the world's deepest rod-pumped oil well on Sept. 21, 1982. Before this installation, the maximum depth experience was limited to about 11,500 ft [3505m]. Its rod pump, installed at 14,500 ft [4420m], has operated successfully since 1982.This rod-lift system replaced a hydraulic lift installation used since the completion of the well in 1966. Poor hydraulic pump operating economics coupled with frequent pump servicing and associated downtime dictated change. Records maintained by the production foreman revealed that Well 41X24D had logged 14 hydraulic pump failures during the previous 12 months of operation. Cost of these failures approached $25,000. During an annual well review, a recommendation was made to convert the well to rod lift to improve the situation.
Our deep-well rod-pumping experience in the Rocky Mountains had been favorable. The theory of the equipment used is discussed in depth.
Introduction to the Reno Field
The Reno field is part of the Rocky Mountain Div.'s Wyoming D/J Unit. It is located in central Wyoming some 90 miles [145km] north of Casper in Johnston County..The field was developed in the mid- to late 1960's. The objective was the Minnelusa sandstone. Zones C and D of the Minnelusa were penetrated initially. Zone D was found to be wet and was squeezed off.
