摘要
伴随国家CGCS2000坐标系的推广使用,我国各大油田存在大量的测绘成果坐标系统转换的任务。以玉门油田探区为例,过去各类测量成果均为1954年北京坐标系成果,需要向CGCS2000成果转换,同时也为了以后使用CGCS2000坐标施工,需要建立统一的CGCS2000控制网并求取相应的转换参数。本文介绍了玉门油田如何建立基于CGCS2000国家大地坐标系统GNSS控制网。根据七参数模型和三参数模型的适用情况,从坐标系统框架建立、坐标转换模型、精度评定等方面介绍了玉门油田坐标系统转换的理论与技术方法,并介绍了开发的相关软件与取得的成果。
With the popularization of CGCS2000 coordinate system,there are a lot of tasks of coordinate system transformation of surveying and mapping results in China’s major oil fields.Taking the exploration area of Yumen oil field as an example,the previous measurement results of Yumen oil field were all the results of Beijing coordinate system in 1954,which need to be converted to CGCS2000 results.Meanwhile,in order to use CGCS2000 coordinates for future construction,a unified CGCS2000 control network needs to be established and corresponding conversion parameters need to be obtained.This paper introduces how to establish GNSS control network based on CGCS2000.According to the application of seven-parameter model and three-parameter model,the paper introduces the theory and technical method of coordinate system transformation in Yumen oil field from the aspects of coordinate system frame construction,coordinate transformation model and accuracy evaluation.The software developed and the results obtained are also introduced.
