摘要

The paper shows the development of the multifunctional ultrasoundimaging logging tool design for casing wells of offshore oilfield inChina. It presents a multifunctional ultrasound imaging logging tool.The instrument can be completed simultaneously casing wall imaging,measurement and an interface damaged casing cement evaluation.Compared with traditional instruments, the instrument has a higherposition and vertical accuracy. Field test results show that themeasurement accuracy of the instrument can be cased hole loggingproject to promote the use. Ultrasonic imaging technology has beenwidely used in recent years in the cased hole logging in engineering.The main issue is to deal with the early completion of the well casingtube cement bonding quality evaluation and the development in the lateemergence of casing corrosion and deformation (there will be moreserious perforation and dislocation phenomena). Developed in thisarticle multifunctional ultrasound imaging logging tool (hereinafterreferred to as MUIL) using ultrasonic pulse echo detection methods, inone acquisition completed cased hole wall, casing thickness and cementcemented wells to 360 evaluation pericyclic imaging. Compared toconventional cement bond logging tool SBT, CBL, etc., MUIL can givethe maximum precision of 3 degrees azimuth cementation evaluation,and through articulated missing azimuth gyro get cement, real fullborehole cementation evaluation. Casing damage detection, dobbycaliper, ultrasonic thickness measurement phase shift, the magneticleakage thickness measurement instruments such as measurementprinciple reasons can not be applied to large size casing. And themeasurement results for the average effect caused by azimuth accuracyis low, it is easy to overlook when measuring tiny casing damage. Theazimuth MUIL high accuracy and vertical resolution in themeasurement of casing damage, to have subtle good application.
