ROP enhancement technique for slimhole drilling in shale oil development
The shale oil development in Sinopec Jiangsu Oilfield is facing the problems of high investment and low production. After 45 years of development, there are a lot of abandoned old wells. Developing shale oil by old borehole side drilling can reduce drilling costs. In 2022, the sidetracking slimhole...

| description | The shale oil development in Sinopec Jiangsu Oilfield is facing the problems of high investment and low production. After 45 years of development, there are a lot of abandoned old wells. Developing shale oil by old borehole side drilling can reduce drilling costs. In 2022, the sidetracking slimhole horizontal drilling in old wells is carried out in Huangzhuang. The slimhole drilling tools have the problems of large flexibility, difficult track control, slow drilling speed, small clearance, large air pressure consumption, poor cementing quality and high well control risk. In order to solve these problems, a system of efficient sidetracking slimhole horizontal drilling technology system is formed by the applications of large casing windowing, well track optimizations, high-efficiency drill bit+screw+LWD geosteering drilling, foam cementing, oil-based drilling fluid plugging, narrow gap well controlling, small hole coring, etc. A test application in H2CHF well shows that the actual drilling speed is up to 5.0 m/h, which is equivalent to the conventional drilling speed in adjacent wells, and the total drilling cost is reduced by 50 %, saved by 15 million. The new development and test would provide important ideas and reference for future development of shale oil in Jiangsu Oilfield. |
