The invention relates to a power and signal transmission intelligent drill stem in the field of directional pipe crossing. The power and signal transmission intelligent drill stem solves the problems of expanding power insufficiency, low signal transmission efficiency and the like during directional crossing. According to the technical scheme of the power and signal transmission intelligent drill stem, a male electric joint, a female electric joint and a cable assembly are connected into a whole and mounted inside a common drill stem; a contact pin assembly is fixed inside a contact pin assembly positioning sleeve, and the contact pin assembly positioning sleeve is fixed inside the female joint end of the common drill stem through a screw; a socket assembly is fixed inside a socket assembly positioning sleeve, and the socket assembly positioning sleeve is fixed at the male joint end of the common drill stem through a positioning block, a pressure block and a screw; cables are mounted inside a cable protecting sleeve, and both ends of the cable protecting sleeve are connected with the contact pin assembly and the socket assembly respectively; three conductors of the contact pin assembly are correspondingly connected with the three conductors of the socket assembly through the cables to form three independent closed circuits; after two drill stems are threadedly connected, the conductors of the contact pin assembly and the socket assembly can automatically form the closed circuits through conductor contacts. The power and signal transmission intelligent drill stem can transmit high-power strong electricity and achieve bidirectional signal transmission.
Description
technical field [0001] The invention relates to an intelligent drill pipe capable of transmitting power and signals used in the field of directional crossing in the installation of water pipes, oil pipes, and natural gas pipelines. The invention can also be used in the field of power and signal transmission where the radial space on the ground is limited. Background technique [0002] With the development of pipeline directional crossing technology, the diameter of the pipeline crossed is getting larger, the crossing distance is getting longer, and the stratum crossing is becoming more and more complex. Horizontal directional drilling operations have become very difficult. For the time being, using a power drill to directly drive the reamer has become the most effective solution. At present, downhole dynamic drilling tools mainly include screw drilling tools and turbo drilling tools. However, they are large in diameter, heavy in weight, difficult in processing and manufact...
