摘要
It is feasible to recommend the appropriate completion method for sour gas fields in the northeast Sichuan based on the relationship between in-situ stress and well trajectory. A predictive model was established, which useed the Drucker-Prage criterion and equivalent plastic strain theory. The results indicated that rock strength of the northeast Sichuan marine strata is high enough to maintain borehole stability during production. Base on the study,appropriate completion method for sour gas fields in the northeast Sichuan Province.
