Abstract

Abstract:

The finite element mechanical model of perforated casing was established in the paper. Under the out pressure condition, the Finite Element Analysis (FEA) of Stress Concentration Coefficient (SCC) in perforated casing was studied with the different perforating diameter, shot density and phasing. The objective is to discuss the effects of SCC and collapse strength of perforated casing in the elastoplastic range. It provided the detail data for the effects of SCC and collapse strength, and presented the optimize scheme for perforating.

Key words: casing, perforating, stress concentration coefficient, collapse strength, FEM

CLC Number:

TE928.01
