查询词典 centralizer

The method for calculating the axial force, bending moment and bending deflection sucker rod string with centralizer is obtained applying compressionalto - shear buckling continuous beam - string theory- The design method for sucker rod string with weighting rod is presented in this paper, which takes the modified Goodman stress diagram as strength design principle and...

应用纵横弯曲连续梁柱理论得到了求解带扶正器的抽油杆柱的轴力、弯矩和挠度计算公式；以修正的Goodman应力图为强度准则，并考虑杆柱刚度条件，提出了水平井中抽油杆柱加重设计的方法。最后给出了某油田1口井的抽油杆柱设计实例，说明了该万法的正确性。

At present, the location of the anti-lopsided wear centralizer used in fields is mainly based on the deviation angle. In fact, lopsided wear may be caused by the change of azimuth angle or by the vertical well section and hold angle section during the working of the bucket rod.

目前油田矿场主要根据井斜角来确定防偏磨扶正器下入位置，实际上方位角变化也能导致偏磨，抽油杆杆柱在运动过程中直井段和稳斜段也会产生偏磨。

The pipe string includes double hydraulic cylinder with anchorage packer、double hydraulic cylinder without anchorage packer、releasing tool、reversing valve and centralizer.

该工艺管柱主要由双缸液压锚定封隔器、双缸液压无锚定封隔器、液压丢手工具、换层开关、扶正器等工具组成。

The pipe string includes double hydraulic cylinder with anchorage packer、double hydraulic cylinder without anchorage packer、releasing tool、reversing valve and centralizer.

胜利油田目前采用的常规换层采油管柱工作寿命短，且需多次起下管柱实现换层，施工程序复杂，作业成本高。

This type of tubing anchor is constitute by anchor body,turnover slip and the centralizer,it is installed in the lower end of the PCP.When the rotor is rotating,it drives the shell and rotary anchor to rotate clockwise.In the role of the friction between turnover slip and the casing,the turnover slip turns over , its outer diameter increases,then it locks to the casing and the anchoring implements.

这种油管锚由锚体，翻板卡瓦和扶正体等组成，安装在螺杆泵下端，泵转子旋转时，带动泵外壳，旋转锚顺时针方向转动，在翻板卡瓦和套管摩擦力作用下，翻板卡瓦向外涨出，外径增大，卡封在套管上，实现锚定。
