The invention discloses an underground turbine and piezoelectric hybrid power generation device. The device comprises an upper drainage pipe, a middle drainage pipe, a lower drainage pipe, a flow guide pipe, a piezoelectric power generation mechanism and a turbine power generation mechanism, wherein the middle drainage pipe is cone-shaped, a water outlet end of the upper drainage pipe is in fluid communication connection with a flaring end of the middle drainage pipe, a necking end of the middle drainage pipe is in fluid communication connection with a water inlet end of the lower drainage pipe, the lower end of the flow guide pipe is arranged in the middle drainage pipe, the upper end of the flow guide pipe is positioned above the flaring end of the middle drainage pipe, the piezoelectric power generation mechanism is arranged on the inner wall of the middle drainage pipe, the turbine power generation mechanism is arranged in the lower drainage pipe, an inner diameter of the upper drainage pipe is D1, an inner diameter of the lower drainage pipe is D2, an inner diameter of the flow guide pipe is D3, D1 is equal to 1.2 to 2 times D2, and D2 is equal to 1 to 1.6 times D3. According to the device, a turbine generator and the piezoelectric power generation mechanism are combined for use, so that not only can a power supply be provided for a monitoring device, but also the power supply can be continuously provided for the monitoring device when the turbine generator breaks down.
Description
technical field [0001] The invention relates to the technical field of downhole power supply for drilling. Specifically, it is a downhole turbine piezoelectric hybrid power generation device. Background technique [0002] In drilling engineering, the measurement of engineering parameters while drilling can monitor the downhole formation pressure in real time, and the operator can adjust the drilling fluid density and wellbore guidance accordingly, thereby improving drilling efficiency. When measuring engineering parameters while drilling, it is necessary to supply power to the monitoring device while drilling, and people use batteries or downhole generators to supply power to the monitoring device. However, most of the existing downhole generators are turbine generators. Once the turbine fails, the power supply of the generator will be weakened or stopped, which makes it impossible to supply power to the monitoring device, resulting in suspension of construction.
