TRAJECTORY CONTROL TECHNOLOGY OF WELL WANGPING-1

Well Wangping-1 is the first medium radius horizontal well drilled in Jianghan Oilfield, and the first trial on developing the non-sand reservoir in this area. Drilling operation is very difficult because of the thin pay zones and the unpredictable geological conditions. This paper describes the geological conditions and trajectory control technology, and focuses on the characteristics, troubles, requirements and solutions on trajectory control. The landing control and horizontal control process are further described, and some recommendations are presented on this technology.
