Abstract

The invention relates to a pressure balance type self-aligning electric drill rod used in the fields of oil and gas drilling, coal mining and pipeline directional crossing. According to the technical scheme, a pin nipple is installed at one end of a drill rod, a socket nipple is installed at the other end of the drill rod, and a pin assembly and a socket assembly are fixed to the pin nipple and the socket nipple respectively through a screw and a supporting frame; the drill rod, the pin nipple and the socket nipple are provided with insulated cables and conducting rings, and the pin assembly, the insulated cable assembly, the conducting ring assembly and the socket assembly are sequentially connected to form two independent current paths; and when a plurality of electric drill rods are connected end to end through threads, an underground conductive path is achieved, power is transmitted to an underground drilling tool, and signals are transmitted to the ground. The pressure balance type self-aligning electric drill rod can realize the functions of automatic aligning, pressure balancing and automatic cleaning, and is convenient to maintain and low in application cost.

Description

technical field [0001] The invention relates to a pressure-balanced self-aligning electric drill pipe used in the fields of oil and gas drilling, coal seam mining and directional crossing of pipelines. Background technique [0002] Modern drilling technology is developing in the direction of informatization, intelligence and automation, and various electric drill pipes that can transmit strong electricity and signals have appeared one after another. Drilling with electric drill pipe often faces problems such as vibration, high voltage and surface contamination of conductive components. Vibration during drilling can easily cause unbalanced loading of the conductive elements of the electric drill pipe, resulting in premature failure of the conductive elements, low electrical transmission efficiency and low reliability; usually the size of the electrical connector parts needs to be increased to meet the mechanical properties of the electrical connector in a high-voltage environ...
