- 摘要:
- 为提高油气田控制测量技术水平和工作效率,介绍了精密单点定位技术(PPP技术)原理及GPS伪距与载波相位观测的计算公式,采用Bernese及TBC软件,分别对某气田首级控制网的中2个C级GPS点、1个检查点及4个首级控制点的观测数据进行解算,将Bernese解算的坐标做投影换算,以3个已知点作为公共点,解算气田区域内平面直角坐标转换4参数,建立转换模型,得到基于IGS的PPP高斯平面坐标,并将Bernese和TBC计算的坐标和高程结果相比较,通过精度和成本分析,得出PPP技术应用于油气田控制测量的可行性结论。
In order to improve the oil and gas field control survey technology and work efficiency,introduced are the principle of IGS precise point positioning technology and the calculation formula of GPS pseudorange and carrier phase observation,Bernese and TBC software are used to calculate observation data obtained from two GPS points with grade C,one check point and four initial control points in initial control network of a certain gas field respectively. Projection conversion is conducted on coordinates obtained from Bernese. Taken are three known points as common points,calculated are four parameters of plane rectangular coordinate transformation in this gas field,established is a transformation model and obtained is the Gauss plane coordinate based on IGS-PPP. Coordinates and elevation obtained from Bernese are compared with those obtained from TBC and their precision and cost analysis results show that application of the IGS precise point positioning technology in oil and gas field control survey is feasible.
