摘要
电磁探伤测井技术可通过油管检测套管现状,提供油/套管缺陷的定量信息和剩余壁厚,是目前套管缺陷检测技术的热点,在降低油气勘探成本、保证油田稳产上具有重大意义。文章阐述了电磁探伤测井技术的优缺点和仪器现状,分析了几种最新电磁套损检测仪的技术指标,结合最新理论成果指出了目前该项技术存在的问题及发展趋势。
Due to the influence of formation stress change,corrosive liquid/gas,water injection,Oil/gas pipeline,casing,tubing easily appear corrosion pit,hole,crack and deformation,which can cause well accident and huge economic loss.Electromagnetic defect detection logging can measure the casing status through tubing,provide quantitative information of oil/casing defects and the remaining metal thickness,which plays an important role in reducing the cost of oil/ gas exploration and guaranteeing the stable production of oil field.This paper elaborates the advantages and disadvantages of electromagnetic defect detection logging and the present instrument situation,compares technical indexes of several new electromagnetic casing defect detection instruments,points out the problems existed in current researches and the development trend combining with the latest theory research.
