摘要： 采气树几何结构复杂，检测空间受限，检测区域定位困难，导致超声相控阵检测采气树内壁冲蚀腐蚀状况存在作业效率低，人为操作误差大的问题。同时，ＨＨ级采气树阀门脖颈内部有耐蚀合金内衬层，精确检测并评估内衬层完好性比较困难。文章通过优化检测参数和成像处理方法，采用自动化定位检测工装与柔性探头组合开展现场检测，结果表明，自主研发的自动化定位检测工装配合柔性探头实现了精准定位和匀速检测，使检测误差低于７％，检测速度提升６０％；优化后的检测参数和成像处理方法能精确识别出ＨＨ级井口装置的耐蚀合金内衬层，检出率达到１００％。超声相控阵检测采用自动化定位检测工装＋柔性探头组合能降低作业风险和强度，适应当前采气树内壁冲蚀腐蚀检测，为采气树服役能力评估提供了可靠的数据支撑。

Abstract:

The geometric structure of the gas tree is complicated, the detection space is limited, and the detection area is difficult to locate. As a result, the ultrasonic phased array detects the erosion and corrosion of the inner wall of the gas tree, which has the problems of low operating efficiency and large human error. At the same time, there is a corrosion-resistant alloy lining inside the neck of the HH-level gas tree, which makes it difficult to accurately detect and evaluate the integrity of the lining. In this paper, by optimizing the detection parameters and imaging processing methods, using automatic positioning detection tooling and flexible probes to carry out on-site testing, it is shown that the self-developed automatic positioning detection tooling and flexible probes achieve precise positioning and uniform speed detection, which makes the detection error lower than 7 % , the detection speed is increased by 60% , and the optimized detection parameters and imaging processing method can accurately identify the corrosion-resistant alloy liner of the HH class wellhead device, and the detection rate reaches 100% . It is concluded that the ultrasonic phased array inspection using the combination of automatic positioning inspection tooling + flexible probe, and optimization of inspection parameter settings and imaging processing methods can greatly improve the efficiency and accuracy of gas tree detection, reduce operational risk and intensity, and adapt to current gas production. The erosion and corrosion detection of the inner wall of the tree provides reliable data support for the evaluation of the service capacity of the gas tree.
