Investigation of heating of the drilling bits and definition of the energy efficient drilling modes
Keywords:temperature settings, drilling, CFD simulation, energy efficiency, pulse flushing
The work deals with the study of processes of heat exchange on a working face of a well when drilling with diamond drilling bits. The urgency of the problem stems from the development of new drilling technologies, where a flushing liquid is supplied in a pulse mode. The aim of the study is the justification of the settings of impulse flushing to enable energy-efficient resource-saving drilling mode. By such modes we understand those with the contact temperature not exceeding 600°C at the specified parameters of drilling.
Experimental study and computer simulation of the processes of heating of drill bits with different modes of flushing were carried out. The task of joint impact of pulse flushing parameters (intervals and pauses) and mode parameters of drilling (flushing fluid consumption and downhole power) on the contact temperature on the working face was solved. On the basis of the obtained data, we designed a nomogram that allows determining the rational values of pause intervals and flushing fluid supply, level of downhole power, flushing fluid consumption, with which energy and resources efficient drilling mode is provided. Thus, the results of this work can be used to control the thermophysical processes on the working face and to select energy-efficient drilling modes.
