王平1井井眼轨迹控制技术

TRAJECTORY CONTROL TECHNOLOGY OF WELL WANGPING-1

王平 1井是江汉油田第一口中曲率半径水平井 ,同时也是用水平井开发王场油田车挡断层盐间非砂岩储层的首次尝试 ,由于目的层薄、地质情况不确定等因素的影响 ,增加了施工难度。介绍了王平 1井的地质情况与井眼轨道设计 ,详细讨论了在轨道控制方面的特点、难点、要求和对策 ,在此基础上 ,对着陆控制和水平控制过程做了进一步的介绍 ,并给出了几点建议。

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.
