塔里木油田地质构造复杂,油气埋藏普遍偏深,深井、超深井钻井工艺复杂、套管柱结构多样,如何准确检测套管磨损和评价固井质量,是测井工程的一大难题。为解决这一难题,油田引进了最新一代的套后成像测井仪Isolation Scanner,该仪器通过脉冲回波测量和挠曲波衰减测量,可对套管磨损、套管居中和固井质量情况进行定量评价。本文介绍了该仪器在塔里木油田的应用情况,通过实例分析认为该仪器应用效果良好。
Tarim Oilfield complex geological structure, generally buried deep oil and gas, deep, ultra-deep well drilling technology complex casing structure diversity, how to accurately detect casing wear and evaluate the quality of cementing, logging engineering is a major problem. To address this challenge, the field introduced the latest generation of Isolation Scanner, a tool that measures casing wear, casing centering, and cementing quality through pulsed echo measurements and flexural wave attenuation measurements Quantitative evaluation. This paper introduces the application of the instrument in the Tarim Oilfield. The practical application shows that the instrument is effective.
