原油管道检测器通过能力评价方法

为了探明管道内部通过能力,保证管道内部腐蚀检测器的顺利投放,制定了由泡沫检测器到几何尺寸检测器的管道通过能力检测流程,并将此方法在多条原油管线上进行了验证。结果表明：该方法能准确地识别管线上的变形尺寸大小,并对变形部位进行定位。根据检测结果对管道通过能力进行评价,对不符合要求的管段及时进行修复,保证了后期检测的顺利进行。此外,在检测的过程中有效地清理了管道内部污物,提高检测器通过能力及管道的输油效率。

Evaluation Method of the Ability of Detector through the Pipeline

In order to measure the through capacity of a pipeline and ensure the corrosion detector to work properly,a test process of through capacity of pipeline from the bubble detector to the geometry detector has been developed,and this method has been verified on several oil pipelines. The results show that the method can accurately identify the size of the pipeline deformation,and locate the deformed parts accurately. According to test results,this paper evaluates the through capacity of the pipeline. The pipe sections that do not meet the requirements are repaired and the testing work is ensured to go on smoothly. In addition, the dirt in the pipeline is cleaned up effectively and the effectively in the detection process,thus improving the indemnification of the through capacity of detector and the efficiency of oil transportation.
