A Downhole Microwave Generating Device Based on Turbine Power Generation

Abstract

The invention relates to an underground microwave generating device based on turbine power generation. The device comprises an upper connector, positioning pins, an upper bearing supporting seat, an upper distance sleeve, a round nut, a power generator rotor assembly, a power generator stator assembly, a lower distance sleeve, a turbine stator, a turbine rotor, a rectifier, a lower bearing supporting seat, an annular connector, a lower shell, a wiring pipe and a magnetron cooling jacket. The upper connector is connected with the upper end of a turbine power generator shell through threads. Theupper bearing supporting seat is fixedly connected to the upper connector through the positioning pins. The magnetron cooling jacket is arranged around a magnetron and connected with the annular connector. The tail end of the magnetron is connected with a waveguide through a flange plate, and a waveguide cooling jacket is arranged at the joint between the magnetron and the waveguide. According tothe underground microwave generating device based on turbine power generation, the structure form that a first-level turbine drives two power generators is adopted, power supply is stable, the adaptive number of revolutions is high, and microwaves can be generated underground stably and efficiently.

Description

technical field [0001] The invention relates to the technical field of petroleum and geothermal drilling, in particular to a downhole microwave generating device based on turbine power generation. Background technique [0002] Drilling is an important link in oil exploration and oilfield development, and rock-breaking technology is the core content of drilling engineering. Improving the efficiency of drilling and breaking rock can develop oil and gas reservoirs economically and efficiently. Microwave rock breaking is a new type of rock breaking technology, which transmits energy to rocks in the form of waves through microwave electromagnetic fields, causing damage to rock mass under the action of water evaporation, internal decomposition and expansion. Microwave can be used as a good auxiliary rock-breaking method because of its advantages of energy transfer without medium, fast heating speed, strong penetration, and easy control of the process. [0003] There are various d...
