- 介绍了管道内检测技术及管道中线坐标的获取现状,分析修正内检测管道数据以获取准确的管道中线坐标的必要性。以某油气公司内检测管道中线坐标修正为例,通过对修正参考点选取、修正参考点测量、内检测坐标修正及油气管道中线坐标验证的内检测油气管道中线坐标修正步骤论述,得出使用基于内检测的油气管道中线坐标修正方法可以使内检测油气管道中线坐标的精度达到±1 m以内的结论。获取准确的油气管道中线坐标对油气管道的安全运营有重大的经济价值和社会意义,基于内检测的油气管道中线坐标修正方法可以在油气行业中推广使用,为内检测油气管道中线坐标的修正提供技术支持。
Introduced are in-line inspection technologies used for oil and gas pipelines and current acquisition methods of pipeline centerline coordinates and analyzed is the necessity of amending pipeline data so as to obtain accurate pipeline centerline coordinates. Taken in-line inspection centerline coordinate correction of oil and gas pipelines of Guangdong Dapeng LNG Co., Ltd. for an example, described are such four steps of in-line inspection centerline coordinates as correction reference point selection, reference point measurement, correction of in-line inspection coordinates and verification of pipeline centerline coordinates and drawn is the conclusion that accurate centerline coordinates with error of less than ± 1m can be obtained by application of the coordinate correction method. Accurate pipeline centerline coordinates have significant economic value and social significance for safe operation of oil and gas pipelines. The correction method for centerline coordinates of oil and gas pipelines based on in-line inspection can be used widely in oil and gas industry and provide technical support for correction of pipeline centerline coordinates.
