摘要： An electric submersible pump (ESP) torque absorbtion anchor system (TAS) and a method to assemble the same are disclosed. The TAS includes a collar having an uphole end coupled to a production string and a flange formed on an outer diameter of the collar. The TAS also includes a sleeve having a rim extending radially inward from an uphole end of the sleeve. The collar is positioned in a cavity of the sleeve so that oppositely facing shoulders of the collar and the sleeve contact and transfer axial loads between the sleeve and the collar. A spring is positioned in an annulus between the sleeve and the collar and mounts to the collar and the sleeve so that rotational loading of the sleeve relative to the collar transfers to the spring.
