TXMECHANICAL ANALYSIS OF TUBING IN THERMAL RECOVERY WELLS

摘要: 本文结合固井和热采过程,建立了井简一地层温度场计算模型,分析了注汽管柱在井内的受力状态,导出了注汽和采油过程中注汽管柱内各种应力的计算公式,给出了注汽管柱的强度校核方法和应用实例。

Abstract: Based on operation processes of cementing and thermal recovery of wells, a mathematical model for calculating dynamic temperatwe of tubing, casing and formation has been established. Factors affecting stresses in tubing have been analyzed. Formulations for calculating stresses in tubing, methods for calculating tubing strength have been established. Field application has been illustrated.
