Abstract

The invention relates to a hydraulically-driven multi-dimensional plasma combined drill bit and a well drilling method thereof. The hydraulically-driven multi-dimensional plasma combined drill bit comprises a drill rod, a drill bit body, a plasma turntable gear, a plurality of plasma devices, a mechanical cutting gear and a power generator, a slurry turbine is arranged in the drill rod, and the bottom of the slurry turbine is connected with the power generator; the bottom of a cylinder on the outer edge of the turbine blade is fixedly connected with a turntable switch, the turntable switch is provided with a plurality of discharge switches in the circumferential direction, each discharge switch extends into an annular slide rail, a pair of cables also extends into the annular slide rail, and the end parts of the pair of cables are provided with switch electric brushes; and an upper gear is welded to the lower end of the turntable switch, the lower portion of the upper gear is engaged with two connecting gears, the two connecting gears are coaxially fixed to the plasma turntable gear and the mechanical cutting gear respectively, and the plasma turntable gear and the mechanical cutting gear are exposed out of the bottom of the drill bit body. Mechanical cutting and plasma impact are combined for rock breaking, and the rock breaking speed is increased.

Description

Technical field: [0001] The invention relates to the technical field of drilling, in particular to a hydraulically driven multi-dimensional plasma combined drill bit and a drilling method thereof. Background technique: [0002] With the depletion of surface oil and gas resources, the depth of wells continues to extend to deeper layers, making it more difficult to break rocks. In deep wells and ultra-deep wells, the rock hardness is high, the mechanical speed is slow, and the drilling cost is high. Many researchers have discovered that the plasma pulse rock breaking technology can efficiently break rocks, and the plasma pulse rock breaking technology has the advantages of no pollution and no flying stones. Plasma pulse rock breaking technology will be one of the important development directions of future drilling technology. At present, this technology still lacks a reliable plasma power supply device. Most plasma drill bits use long-distance power transmission for power su...
