摘要
分析了螺杆泵井井口愈高运行愈不稳的原因 ,并针对现用螺杆泵井井口的结构及运行情况设计了螺杆泵专用矮型井口 ,该井口不但具有现用井口的所有功能 ,而且具有制造成本低、运行平稳。
The reasons for screw pump to operate more unsteadily with the increase of the height of screw pump wellhead are analyzed.On the basis of the structure of existing wellhead,the special low wellhead for surface driven screw pump well is designed.The wellhead not only has all the functions of existing wellhead,but also many advantages,such as low manufacturing cost,steady operation and reducing labor intensity of the work etc.
