| 摘 要： | 加拿大白桦地项目是中石油与壳牌合作开发的非常规致密气项目,该地区致密气的开发以长水平段的水平井为主,平均水平段长度为2 200 m,最长水平段长度达到3 600 m。采用工厂化钻完井技术施工,即批量钻井、批量压裂等新型钻完井作业模式,并配以高效实用的常规导向或高新的旋转导向钻井技术、高效PDC钻头和油基钻井液,不仅提高了作业效率,降低了作业成本,也更加便于施工和管理,特别适用于非常规油气资源的开发作业。

| Abstract: | Canada Groundbirch project is the first cooperation of CNPC and Shell on unconventional tight gas. The tight gas in this region is mainly developed by long horizontal wells, which have an average horizontal section of 2200m and the maximum horizontal section of 3600m.The wellpad drilling, a new type of drilling and completion operation mode invovling batch drilling and fracturing and so on, together with conventional geosteering or new rotating steering, high efficient PDC drill bits and oil base drilling fluid, can not only improve the working efficiency and reduce the operation cost but also is more convenient for well construction and management, and especially suitable for unconventional oil and gas resources development. |
