    Abstract：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.
