Abstract

As a key problem in drill string dynamics, drill pipe stick slippage in deep wells and large displacement horizontal wells may cause drilling tool performance dropping and tool failure to lead to underground accidents.Therefore, studying sticky slip reduction technology has important guiding significances for effectively improving machinery’s rotating speed, shortening well-built period and ensuring safe operation.Here, based on the dynamic model of sticky slip process with longitudinal-torsional vibration coupled, a new constant torque tool was proposed.This new tool was taken as the study object to study its working mechanism.According to production data, the theoretical method established was used to do example analysis including longitudinal and torsional dynamic results.The example results were compared with the field data.The study showed that due to the constant torque effect produced by the new tool with longitudinal-torsional coupling, the torque fluctuation of the new tool can be effectively reduced to avoid the hysteresis phenomenon and make effective rock breaking behavior be continuous and stable when drilling for rock breaking in soft and hard inter-leaving zones.The proposed new constant torque tool provided a reference for improving techniques of sticky slip reduction and increasing speed and efficiency.The established theoretical dynamic model promoted the development of drill string dynamics under new drilling conditions.
