| 摘 要： | INTRODUCTION Oil and water well is an important basic estab- lishment in oilfields. In many oilfields, there are many different damages in the well’s casing walls after its development for a period of time. They will affect the normal production of damaged wells and adversely influence the neighbouring wells and the block, and threaten steady production. There are different kinds of damages due to multiple problems in the casing walls, for example, corrosion, perforation, decreased diame…

| Abstract: | UTT (Ultrasonic Tomography Tool) is widely used in the oil industry and can be used to inspect corrosion, casing wall damage, casing breakoff, and casing distortion in the well borehole with the maximum environment temperature being 125℃, and the pressure being 60 MPa. UTT consists of tool head, upper centralization, electronic section, lower centralization, transmitters,and receivers. Its outer diameter is 4.6 cm and length is 320 cm. The measured casing diameter ranges from 60 mm to 254 mm. The tomography resolution is 512×512. The borehole measurement accuracy is 2 mm. It can supply 3D pipe tomography, including horizontal and vertical profile. This paper introduces its specification, measurement principle, and applications in oilfield. |
