Abstract: The geological and engineering conditions of Niuye Block I are complex in Shengli Shale oil Field. In order to improve the quality of directional drilling in this block, the study on rotary steerable drilling technology had been carried out. Through research and application exploration on the technologies such as rotary steerable system and matching tool optimization, 3D trajectory design and trajectory control, built up rate prediction and correction, high temperature risk prediction and control, these methods had been established, including the optimization template for bottom hole assembly, trajectory control strategies, the standard instruction set for steering forces, and the procedures for high-temperature operations. Then, a standard operation mode for rotary steerable drilling in shale oil was formed, and it had been applied in 20 wells in Niuye Block I. The application results show that this operation mode can effectively improve the rate of penetration, increase the footage of single run and single well, and realize the construction of 2000 m long horizontal section in the area. The research results have provided a new technical approach and application template for the efficient development of shale oil resources in the Shengli Shale Oil Field.
