摘要
在石油天燃气勘探开发中,油气井能否充分利用、正常生产及寿命长短关键在于固井质量的好坏。随着油气勘探开发的深入,超深井、水平井、厚套管井及“三高（高温、高压、高含硫）”气井,给固井质量测井评价技术提出了新的要求。采用多层套管完井,最多可达四层（13-3/8＂ ＋9-5/8＂＋7＂＋5＂）套管的四川气井埋藏深度一般在2500～6500米左右。本文主要介绍固井质量的用途及优缺点,声波变密度测井评价,固井声波变密度测井主要影响因素分析。
In oil and gas exploration and development,whether an oil or gas well can be made full use or produces reguhrly and lifespan is long or not depends on the cement bond quality.With development of oil and gas,super-deep well,horizontal well,thick cased well and'3H'(high temperature,high pressure,high sulfur)gas well bring forward higher requirement for well logging evaluation technology of cement bond quality.The buffed depth of a gas well in Sichuan is generally about 2500~6500m with multiwall easing completion at most four layers (13-3/8'+9-5/8'+7'+5').This paper introduces the use,merits and demerits of cement bond quality and primary affecting factor analysis in acoustic variable density logging evaluation and cementing acoustic variable densit logging.
