Deep well while-drilling temperature difference power cabin

Abstract

The application discloses a deep well drilling temperature difference power cabin, belongs to the field of deep drilling, and comprises an upper joint, an outer shell and a lower joint which are sequentially and threadedly connected from top to bottom, and further comprises a flow channel and a thermoelectric power assembly, wherein the thermoelectric power assembly is arranged in the outer shell, the flow channel is a hollow tubular structure with open ends, and the upper joint, the thermoelectric power assembly and the lower joint are connected in series on the flow channel; the thermoelectric power assembly comprises a thermoelectric generation system, an electric energy transfer system and an electric energy output system; the application recycles and utilizes the downhole heat energy by utilizing the temperature difference between the downhole high-temperature environment and the drilling fluid, can improve the energy self-sufficiency rate of the downhole power consumption element, reduces downhole accidents caused by power shortage of the power consumption element, greatly improves the drilling efficiency, and has the characteristics of small noise, green environmental protection and the like, and has the advantages of working together with other equipment.
