摘要
为了解决吐哈油田固井质量精细化评价问题,2011年引进了扇区水泥胶结测井SBT并在吐哈油田成功应用。文章介绍了该仪器测井原理、刻度方法、解释标准,并通过编程计算出用于评价第一、二界面胶结质量的胶结比BR,水泥抗压强度,水泥缺失率等关键参数,文章还列举了二口井的应用实例。
In order to resolve the refined cement evaluation problem,accurately direct the high pressure task problems same as exact direction fracture, perforation,acidulation,etc.,rationally evade tiny annular,bypass channel, set plug at effective hole section,and locate thief zone and bypass channel use in old well,the sector cement bond log SBT technology is introduced to Tuha oilfield and has successful use in Tuha oilfield.This paper describes the logging theory,calibration method interpretational criteria.BR,cement compressive strength,cement deficiency rate for evaluating first interface and second interface cemented quality are calculated,and realize in LEAD software.The paper gives two practical application examples of the SBT.
