Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] Such as figure 1 As shown, the self-powered intelligent drill pipe system of the present invention includes a plurality of drill pipes 10. The drill pipes 10 may be existing drill pipes of various structures, and the number of the drill pipes 10 is determined according to the specific application site.
[0028] Both ends of each drill rod 10 are provided with data transmitters 20 , the data transmitters 20 at both ends of the same drill rod 10 are connected by a data transmission line 30 , and the data transmitters 20 between two adjacent drill rods 10 are wirelessly connected.
[0029] The data transmitter 20 is used to transmit data, specifically MSP430 series such as MSP430fr6989 and MSP430fr2433, wireless communication modules such as CC1101 and CC115L, ultra-low power consumption MCUs such as STM32 series and Apollo3 Blue Wireless SoC, Ambiq...

The invention discloses a self-powered intelligent drill rod system. The self-powered intelligent drill rod system comprises a plurality of drill rods, wherein data transmitters are arranged at the two ends of each drill rod, the data transmitters at the two ends of the same drill rod are connected through a data transmission line, and the data transmitters between every two adjacent drill rods are in wireless connection; and a power generation module is arranged in each drill rod, each power generation module is connected with an electric energy management module, and the data transmitters are connected with the electric energy management modules. The invention further provides an underground data transmission method. The power generation modules are arranged in the drill rods, and kinetic energy of slurry is used for generating power, so that the data transmitters and other elements are powered autonomously; and the data transmitters at the two ends of each drill rod are connected through the data transmission line, data can be transmitted mutually, the data transmitters between every two adjacent drill rods are in wireless communication connection, and the data can be transmitted between the drill rods, so that a reliable data transmission chain is formed, all drill rod data are summarized, underground data transmission is realized, and accuracy and stability of data transmission are guaranteed.
Description
technical field [0001] The invention belongs to the technical field of petroleum exploitation, in particular to a self-powered intelligent drill pipe system and a downhole data transmission method. Background technique [0002] As the most important energy fuel in the world today, petroleum resources are known as "the blood of modern industry". Due to the continuous increase in the demand for petroleum resources in recent years, drill pipes are important core equipment for oil and gas resource exploitation, and related products have not yet realized intelligence. The overall integration of drill pipes lacks systematic research, and related technologies are in urgent need of transformation and upgrading. [0003] Generally speaking, the development of drilling technology in the world is generally divided into four stages: empirical drilling, scientific drilling, automatic drilling and intelligent drilling, among which intelligent drilling is the most mature stage of current t...
