Finite Element Analysis of Perforated Casing High Stress Area Compressed Volume Coefficient

LI Wei, YANG Bin, CHEN Sitong

Abstract


In view of the problem that perforation completion result in casing damage, from the perspective of perforating casing overall stress, on the basis of plate and shell opening mechanics model, establishing the cloth of spiral casing perforation holes finite element mechanics model, reflecting the area around the hole stress change after the casing perforation clearly. Comparing different perforation parameters before and after perforating casing under the condition of high stress area volume ratio, concluding the high stress area compressed volume coefficient, Analysis of the differential pressure under the condition of normal production, the influence of different perforation parameters (bore diameter, shooting density, phase angle) to the perforated casing compressed volume coefficient. The results of the analysis shows that different perforation parameters on the perforated casing all affect the compressed volume coefficient. According to the characteristics of the different effect law to different parameters, providing the optimization scheme of perforating parameters that reducing the volume coefficient of perforated casing high stress area. On the whole to reduce perforated casing high stress area compressed volume under normal production conditions.
Key words: Perforation; Casing failure; Finite element method; High stress area; Compressed volume coefficient
