哈里伯顿套管检测仪器的技术特色

Technical features of Halliburton casing inspection tools

油田开发后期套管损坏越来越严重 ,人们希望尽快提高套损检测技术水平。通过分析哈里伯顿各种套损检测仪器的传感器结构和现场测井资料 ,认识到探头的阵列化和独立化是提高仪器周向分辨能力的主要途径 ,成像使测井资料更加直观。组合方位井斜、井径成像、超声成像和阵列磁法 。

The casing damage becomes more and more serious in China oilfields,casing inspection technique must be improved quickly. By analyzing sensor structures and field well logging data of some Halliburton casing inspection tools,the conclusion is that independent acquisition with detector array is a main approach to increase circumferential resolution,and imaging makes well logging more visual,as well as combination of azimuth deviation logging,caliper imaging,ultrasonic imaging and magnetic array logging can enhance casing inspection accurary.
