摘要
MIT-MTT (多臂井径成像测井仪-磁壁厚测井仪)组合测井资料解释软件在分析处理数据时,能采用多条井径曲线和12条壁厚曲线生成井筒截面图来评价套管损伤。在该基础上引入圆弧插值技术,在井眼或套管内径圆周上实现等间隔和非等间隔插值,增加测井信息量来形成井筒截面图,达到整体评价套管状况的目的。该技术在CIFLog-Geomatrix解释平台中应用结果表明,经圆弧插值技术处理后,MITMTT组合测井资料形成的井筒横截面图更形象、具体,能够更好地评价套管损伤程度及类型。
In the processing of data with MIT-MTT combined logging data interpreting software tools,casing damage could be evaluated by using multiple diameter curves and 12 wellbore thickness curves to generate wellbore cross-section diagrams.On that basis,circular interpolation algorithm was introduced to realize equal-interval and non-equal-interval interpolation on the circumference of borehole or casings,increase the logging information to form the wellbore profile,and achieve the purpose of overall evaluation of casing condition.The application of this technique in CIFLog-Geomatrix interpretation platform shows that after processing by circular interpolation,the MIT&MTT presents more specific and visualized logging sections,and it can better evaluate the degree and type of casing damage.
