When a monobarrel subsurface tubing pump works in adeep well. its barrel bore expands due to the inside fluid pres-sure and contracts due to both bottom pressure and axial load.Investigation indicates that the above--mentioned contraction isvery slight and the amount of the foresaid expansion is propor-tional to the pump diameter, however also not large after all.Under general circumstances, the inf?uence of bore variation onpump efficiency is negligible. When pumping low viscosityfluids in deep wells, it is recommended to increase appropriatelythe length of plunger and stroke, in order to reduce the elasticdeformation of the string.

整筒管式抽油泵在深井中使用时,泵内液体压力使泵筒内径扩张,井底压力和轴向载荷使泵筒内径缩小。分析计算表明,泵筒内径由轴向载荷和井底压力引起的缩小量极小;由泵内压力引起的扩张量与泵径成正比,但扩张变形量并不大,对泵效影响甚微。因此,在一般情况下无需考虑泵筒内径变化就影响,在深井稀油工况时,可适当增加柱塞长度、冲程长度和减少管柱的弹性受形。
