product description:

   A supporting slip for an oil field screw pump production well solves the problem that the original supporting slip cannot pass through a reduced-diameter well section. Specifically, it includes a main body on which slips and a friction block are connected; the connecting body of the slips and the main body is placed in the oil well and can pass through the reduced-diameter well section smoothly; the friction block has a built-in radial elastic member; The radial elastic member is used to ensure that the slips can normally expand in the large-diameter casing after passing through the reduced-diameter well section to ensure the setting effect. In this application, by reducing the outer diameter of the slips, increasing the setting angle of the slips, and increasing the spring force of the friction block, the supporting slips can not only pass through the reduced-diameter well section, but also ensure that the supporting slips are in the normal casing after passing. The card can guarantee the effect of sitting in the tube.

Features:

   1. An oil field screw pump oil well supporting slip, characterized by comprising: a main body; slips and friction blocks are connected to the main body; the connecting body of the slip and the main body is placed in the oil well, which can smoothly Through the reduced-diameter well section; the friction block has a built-in radial elastic member; the radial elastic member is used to ensure that the slips can normally expand in the large-diameter casing after passing through the reduced-diameter well section to ensure Setting effect.
