摘　　要：连续油管作业时对其壁厚与椭圆度有要求。在分析国内外连续油管检测系统基础上,根据超声波检测原理,对超声波信号的壁厚测量以及连续油管管体椭圆度测量原理进行了详细描述,并提出了一种连续油管壁厚与椭圆度超声波检测系统设计方案。该方案采用椭圆度优化算法,提高了壁厚及椭圆度测量参数精度,可为连续油管超声波检测器样机研制提供理论依据。Aiming at the requirements of the thickness and ovality for the coiled tubing operation and based on the analyzed coiled tubing inspection system at domestic and aboard, and according to the principle of ultrasonic inspection, the measurement scheme of coiled tubing wall thickness and ovality by ultrasonic inspection was carried on. And the scheme adopts the ovality optimiza- tion algorithm,which improved the precision of wall thickness and ovality measure parameters. Finally result can provide theoretical basis for coiled tubing ultrasonic inspection prototype.
