| Abstract:Based on the in-depth analysis on the factors that restrict the drilling rate in Fuling shale gas field, National Oilwell Varco put forward a scheme aiming at improving the drilling efficiency in this area. A large number of field practices based on this scheme have been carried out so far. This paper gave a full description of the assembly of NOV-made drilling tools of rotary impactor, hydraulic oscillator and POB（power-plus oil-based mud） downhome motor as well as the related technical principles. The performances and advantages of these tools in the application in Fuling block are elaborated comprehensively and some technical shortages are presented. The implementation effects show that the drilling rate improving scheme of NOV is practical and has important guiding significance for the selection of drilling technology in the late stage of the optimized and fast horizontal well drilling. |
