Abstract

The application of supercapacitor energy storage device in the microgrid system of ultra-deep well oil drilling rig can effectively recover the regenerative energy generated when the winch lowers the drilling tools. Firstly, a microgrid system model of super capacitor energy recovery for ultra-deep well oil drilling rigs was established; the theoretical recoverable energy during a complete operation of ultra-deep well drilling rigs was calculated; the economic efficiency of energy recovery was calculated by taking into consideration of a variety of economic factors, such as storage cost, pollutant emission reduction benefit, and storage loss, etc. was taken into account as the objective function of energy management and capacity allocation optimisation of super capacitor energy storage devices. Using genetic algorithm to solve the supercapacitor capacity configuration, when the well depth is 9000 m, the economic efficiency can reach 26.4% by using 5×377 supercapacitor combination; when the well depth is 12000 m, the economic efficiency can reach 32.7% by using 5×650 supercapacitor combination. It provides a corresponding reference to help improve the economic efficiency of the microgrid system for energy recovery of oil drilling rigs in ultra-deep wells.
