热采井套管柱力学分析

MECHANICAL ANALYSIS OF CASING IN THERMAL RECOVERY WELLS

摘要: 本文结合固井和热采过程,分析了套管柱在井内的受力状态,导出了注汽和采油过程中套管柱内各种应力的计算公式,给出了套管柱强度校核方法和应用实例。

Abstract: Based on the operation processes of cementing and thermal recovery of wells, factors affecting stresses in casing have been analysed. Formulations for calculating stresses in casing have been established. Practical examples are illustrated.
