Abstract

To understand the mechanical behavior of composite bridge plug anchoring casing, the mechanical properties of two types of slip are studied in this paper. The finite element method was adopted to simulate the mechanical behavior of the milled slip and the hard alloy slip, respectively. The results showed that the maximum stress of the casing was 780 MPa when the seating force of the milled slip reached 150 kN, and the deformation of the casing was relatively serious. The hard alloy slip can play an anchoring role when the seating force is about 150 kN. Moreover, the milled tooth slip could not effectively hold the casing. And the bite marks on the inner wall of the casing are deeper when the casing is fixed with hard alloy slip. It is concluded that the hard alloy slip can effectively achieve the anchoring effect. The conclusion has a certain guiding effect on the design and application of composite bridge plugs. [ABSTRACT FROM AUTHOR]
