摘要
井筒完整性贯穿于油气水井的全生命周期,有效的井筒屏障阻绝了地层流体的不可控泄漏,进行精确的井筒完整性评价对保障油气井安全运行具有重要意义。当前井筒管柱完整性测井评价技术较多,但部分技术在精细找漏方面存在局限,该文对比分析了常用的井筒管柱完整性测井评价技术的特点,提出可通过多种组合测井方式提高窜漏检测的精确性,同时引入分布式光纤温度测井技术,应用实例表明井筒管柱完整性测井评价技术可靠,为井筒精细找漏提供思路。
Wellbore integrity runs through the whole life cycle of oil,gas and water wells.Effective wellbore barrier eliminates uncontrollable leakage of formation fluid.Accurate evaluation of wellbore integrity is of great significance to ensure the safe operation of oil and gas wells.At present,there are many wellbore srting integrity log evaluation technology methods,but some methods have limitations in fine leakage detection.This paper compares and analyzes the characteristics of common integrity log evaluation technology methods,and puts forward that the accuracy of channeling and leakage detection,which can be improved through a variety of combined logging methods.At the same time,the distributed optical fiber logging technology method is introduced.With the application results,the reliability of wellbore string integrity log evaluation technology is verified,which provides a fine idea for finding leakage.
