Abstract
The invention discloses an ultrasonic phase-array imaging detection device and method for a blowout control / relief pipeline. The design is that an ultrasonic phase-array detection instrument serves as a host, and a scanning device and a coupling device serve as auxiliary devices. When the ultrasonic phase-array imaging detection device is used for detecting the blowout control / relief pipeline with the external diameter of phi 127-196 mm and a paintcoat, a probe with the corresponding size is selected, the scanning device is pushed to reciprocate along the axis of a pipe body, the circumference of the pipe body is covered by not less than 120 degrees every time, and scanning is accomplished in three times. In the scanning process, waveform scanning A, scanning B and scanning C detection technologies are integrally applied, the ultrasonic phase-array imaging detection instrument displays scanned defective images and waveform in real time and reflects the detection situations in multiple angles, and accordingly, the quality of the pipe body of the blowout control / relief pipeline is judged. The whole detection process requires not more than 10 min.
Description
technical field [0001] The invention relates to the quality detection of a blowout prevention / blowout pipeline of a well control device in petroleum drilling engineering, in particular to an ultrasonic phased array imaging detection device and a detection method of a blowout prevention / blowout pipeline. Background technique [0002] As the requirements for well control safety in the oil drilling process are getting higher and higher, the technical performance and quality requirements for well control devices are also getting higher and higher. According to the well control management regulations, it is necessary to conduct regular inspections on the blowout prevention / blowout pipeline. [0003] At present, the commonly used detection methods for anti / blowout pipelines include ultrasonic and magnetic particle inspection methods, which are mainly used for random inspection of the quality of Xinguang pipe fittings before the manufacture of anti / blowout pipelines. Some manufact...
