摘　　要：随着国家CGCS2000坐标系统的推广使用,我国石油行业存在巨大的坐标系统转换需求。以沁水盆地为例,基于已有国家控制点并新增部分控制点,构建了研究区GNSS控制网,再采用静态观测对各控制点进行两时段的连续观测,然后对观测数据进行处理与解算,求取研究区坐标转换参数,转换成果经过精度验核满足石油行业精度要求。实践表明,GNSS静态观测技术具有精度高、野外操作适应性强、成本较低的特点,适用于石油行业的坐标系统转换。With the promotion of the national CGCS2000 coordinate system, there is a huge demand for coordinate system transformation in our petroleum industry. We used existing national control points and adding some new mores in Qinshui Basin to construct a GNSS control network at first. Then, we observed the coordinates of all control points by static observation method continuously. Finally, we processed and calculated the observation data, and obtained the coordinate transformation parameters of the study area. The results met the accuracy requirements of petroleum industry after accuracy verification. This practice shows that the GNSS static observation technology has the characteristics of high accuracy,strong adaptability to field operations and low cost, and is very suitable for the petroleum industry’s coordinate system transformation.
