摘要
为解决国内外油气田长输管线控制测量中控制网覆盖广、地形复杂、工期紧以及找点困难、联测不便等问题,以非洲某油田长输管线建设为例,采用精密单点定位解算软件和TBC软件,分别对已有控制点和新布设首级控制点的观测数据进行解算,并将解算结果进行比较分析。结果表明:精密单点定位技术解算结果的平面坐标精度优于2 cm,高程精度优于5 cm,精度指标均满足规范要求。精密单点定位技术在长输管线控制测量中应用是可行的,为国内外长输管线作业困难地区的控制测量提供了便捷的方法,同时也可以节省人力、物力,缩短作业周期,极大地提高作业效率。
To solve the problems of oil and gas long distance pipeline control survey both at home and abroad,such as the control network covers a wide area,the terrain is complex,the construction period is tight,the point finding is difficult,and the joint test is inconvenience,taking the long-distance pipeline construction of an oilfield in Africa as an example,precise single point positioning software and TBC software are applied to calculate the observed data of existing control points and newly established primary control points respectively,and the calculated results are analyzed in comparison.The results show that the accuracy of plane coordinates and elevation are better than 2 cm and 5 cm,respectively,which meet the standard requirements.The results show that the precise single point positioning technology is feasible in the control survey of long distance pipeline.The application of precise single point positioning technology in the control and measurement of long-distance pipeline is feasible,which provides a convenient method for the control and measurement of long distance pipeline in both domestic and foreign areas with operation difficulty.At the same time,it can save manpower and material resources,shorten the operation cycle and greatly improve the operation efficiency.
