| 1. | Wellhead bias - adjustable device for rod - pumped well 抽油机井井口调偏装置 |
| 2. | Energy saving mechanism in the application of gas anchors to rod pumping wells 抽油机井应用气锚的节能效果 |
| 3. | Neural network - based fault diagnosis expert system for rod pumped well 基于神经网络的抽油机井井下故障诊断专家系统 |
| 4. | A measurements of the well depth and indicator diagram are studied in the dissertation 设计了测量油井液面深度和抽油机井功图的双参数测井仪。 |
| 5. | Development and application of blowout hookup for polish rod breaking and dropout in rod - pumped well of high pour - point oil field 高凝油油田抽油机井光杆断脱防喷装置的研制及应用 |
| 6. | Statistically , rod - pumped wells occupy 94 percent of the whole oil wells , and the output is 87 percent of the raw oil ' s whole output 据统计,抽油机井占油井总数的94 ,产量占原油总产量的87 。 |
| 7. | Meanwhile coaxial line phase water cut meter has realized dynamic measuring of oil well water cut . and the detecting results objectively represent flowing state in pumping wells 同轴线相位法含水率计实现了油井含水率的动态测量,其测量结果客观反应了抽油机井中油水两相流动状态。 |
| 8. | According to the energy conservation law and presupposing not to change the times of total rotation of pumping units every day , the flush times are changed to adjust the load shape in order to realize power consumption by peak load cutting 根据能量守衡定律,在保证抽油机每天运转总冲数不变的前提下,用改变抽油机井冲次的方法来调节负荷,达到油田避峰用电的目的。 |
