Abstract:
Purpose. The creation of scientific and methodological basis for increasing a reliability and energy efficiency of power supply systems and electrical equipment of oil and gas industry drilling units.
Methodology. The mathematical models of an electrotechnical complex functioning of a drilling unit are synthesized with taking into account technological factors of influence on reliability and energy efficiency during drilling of wells by an electric rotation downhole motor. It allows working out measures to increase the reliability and energy efficiency indicators of electrically driven drilling units.
Findings. Mathematical models of reliability and energy efficiency of power supply systems and electrical equipment of a drilling unit in programming medium of virtual LabVIEW devices have been constructed. The power parameters of electrically driven drilling units have been experimentally obtained by using information-measuring control system of power parameters. The influence of technological and power parameters on reliability and energy efficiency of the electrical drilling equipment has been defined. The requirement of working out the organizational and technical actions directed at the improvement of the electrical drilling equipment functioning has been substantiated.
Originality. The influence of drilling mud temperature in a well on resistance of the electric rotation downhole motor of the electric power supply system has been considered. It has been established that the current spectrum of the submersible electric motor of the electric rotation downhole motor does not contain an inadmissible level of higher harmonics, but asymmetry of currents and voltage decreasing at the electric rotation downhole motor terminals in operation modes occur.
Practical value. The created mathematical models allow predicting the value of the basic indicators of energy efficiency and serviceability of electrotechnical complexes of drilling units on the basis of technological and power parameters for the purpose of an optimal operation mode choice.
