Abstract

The invention provides a phased array probe and a phased array instrument, and relates to the technical field of checkout equipment. No matter whether a thread is machined in an oil casing coupling or not, the oil casing coupling can be effectively detected; the process is simple, time is saved, and work efficiency is improved. The phased array probe is used for conducting flaw detection on the oil casing coupling, and comprises a wedge block and an energy transducer, wherein the wedge block comprises a concave arc-shaped bottom face and an inclined face opposite to the concave arc-shaped bottom face, a preset included angle is formed by the central axes of the inclined face and the concave arc-shaped bottom face, the energy transducer comprises a body and a plurality of wafers, the body comprises a connecting face, the wafers are embedded in the connecting face, the connecting face is opposite to the inclined face, and the wafers are attached to the inclined face and distributed in arrays at intervals along the first straight line in the inclination direction of the inclined face. The phased array probe is mainly used for conducting flaw detection on the oil casing coupling.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a phased array probe and a phased array instrument. Background technique [0002] Usually the connection between oil casings is connected by oil casing collars. The oil casing collars have internal threads, and the two casings are connected through threaded connections. In order to ensure the sealing of the joints, the accuracy of the threads must be Strict requirements, and the coupling must not have defects such as cracks, pores, pits, etc., so the oil casing coupling must be tested. [0003] At present, the detection of oil casing couplings needs to be divided into two parts. When the oil casing couplings are not threaded, the blanks are first subjected to ultrasonic non-destructive testing. Ultrasonic flaw detectors can be used to propagate ultrasonic waves in the blanks. Refraction and reflection will occur on the interface at different interfaces. By observing ...
