Problems solved by technology
The drill pipe joint technology is the bottleneck that inhibits the development of signal transmission drill pipes, and the current drill pipe joint technology is not high in safety and sealing reliability in corrosive and abrasive high-pressure drilling fluids, and there are joints after repeated use. The problem of the decline in electrical conductivity, so it is imminent to develop a drill pipe joint technology with high safety and sealing

The invention relates to a power and information transmission drilling rod conducted by an elastic claw slip ring. The power and information transmission drilling rod comprises a drilling rod body, a slip ring male joint and a slip ring female joint. The slip ring male joint comprises a female joint slip ring main shaft, female joint copper rings, a female joint slip ring insulator and a high voltage wire. The slip ring female joint comprises a male joint slip ring main shaft, a sealing gasket, a male joint slip ring insulator and male joint copper rings. The slip ring male joint is fixed on the drilling rod body through fixing nuts in a screw type, the slip ring female joint is fixed on the drilling rod body through a jump ring, and an armoured cable is arranged between the slip ring male joint and the slip ring female joint. When the male joint and the female joint of the drilling rod are connected and buckled, the slip ring male joint is automatically inserted into the slip ring female joint, the male joint copper rings are elastically contacted with and conducted with the female joint copper rings, communication of electric power and signals is achieved, the conductivity of the joints are not reduced after the joints are used repeatedly, the safety of the drilling rod joints is improved to a great extent, and therefore processing and on-site operation are relatively simple, convenient and fast.
Description
technical field [0001] The invention relates to the field of oil and gas drilling tools, in particular to a drill pipe used for power and information transmission. Background technique [0002] With the continuous development of modern rotary steerable drilling technology, geosteering drilling technology such as logging while drilling and seismic technology while drilling, downhole diagnosis and control technology of drilling dynamic parameters, the amount of downhole information required for measurement while drilling increases, and requires The process can collect, transmit, process, feed back and apply various geological and wellbore information in real time while drilling, so that the construction process can be adjusted in time to ensure fast and safe operation. At present, the existing drilling fluid pressure pulse technology and electromagnetic wave transmission technology will not be able to meet the needs of real-time and large-capacity transmission of downhole info...
