Roller bit with temperature monitoring and cooling functions

Abstract

The invention provides a roller bit with temperature monitoring and cooling functions, and belongs to the technical field of roller bits. The roller bit comprises a bit body, a temperature sensor, a rotating speed sensor, a cooling mechanism and a control system, wherein the bit body is provided with a cavity, a cooling channel is arranged in the bit body, the temperature sensor and the rotating speed sensor are used for monitoring the temperature and the rotating speed of the cone in real time, the cooling mechanism is arranged in the cooling channel and provided with a water spraying assembly which can move in the cooling channel in the height direction of the drill bit body and can stretch out of the upper end of the cooling channel, and the water spraying assembly is used for spraying a cooling liquid to the cone to reduce the temperature of the cone. The control system is arranged in the cavity and used for receiving temperature and rotating speed information and controlling the cooling mechanism to operate. The device has the technical effects that the real-time working temperature and the rotating speed of the roller bit can be monitored in real time in the drilling process of the roller bit, the drill bit is cooled in time, the working state is monitored in time, information is fed back in time, the drill bit is reasonably used, and the service life of the drill bit is prolonged.

Description

Technical field [0001] The present invention belongs to the technical field of roller cone bits and, more particularly, is directed to cone bit having a cooling and temperature monitoring functions. Background technique [0002] Cone bit is the most widely used in oil drilling rock-breaking tool, their effectiveness and working life has a very important impact on drilling and drilling costs. Cone bits depending on the working life of the working life of the drill bit bearings, and the factors that affect the use of the drill bit comprises a bearing life factors (such as WOB, rotational speed, depth, well temperature, etc.), manufacturing quality (e.g., the bearing gap, materials and heat treatment, surface quality, sealing, lubrication, etc.). Few of the prior art roller bits working temperature, pressure and speed of real-time monitoring technology, work status cone bit in the drilling process can not be monitored in real time, the staff can not grasp the real-time status of dri...
