Problems solved by technology

[0004] The purpose of the present invention is to provide a cable storage and delivery system for the downhole torque self-balancing cabled drilling system, so as to solve the problem that the cable pipe is easily squeezed on the drum and the cable drum is rotated on the drawworks when the existing drawworks is used to lift the drill tool. The fixed end of the pipe and the static part of the ground are difficult to overcome the dynamic and static sealing and the electro-hydraulic isolation technology in the dynamic and static state, simplify the mechanism and improve the drilling efficiency

Embodiment Construction

[0028]In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. It should be understood by those skilled in the art. The content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention. "First", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" used in the embodiments of the present invention do not mean In any order, quantity or importance, but only to distinguish different components.

[0029] see Figure 1 to Figure 9 , the present invention proposes a self-balancing drilling tool system cable ground bionic storage system, which is composed of a coiled cable storage mechanism, a cable storage and introduction mechanism, and a cable delivery and injection mechanism. The snake-like coiled cable tube storage mechanism includes a cable storage platform 1...

Abstract

The invention discloses a bionic cable conduit ground storage system for a self-balancing drilling tool system, and relates to the technical fields of boring and drilling. The storage system is composed of a snake coiling imitated cable conduit storage mechanism, a cable conduit storage introducing mechanism and a cable conduct conveying and injection mechanism. The problem that a cable conduit tends to offset on a roller in a lifting drilling tool of a present winch is solved, and the difficulty in electro-hydraulic isolation technology in dynamic-static sealing and dynamic-static states of acable conduit fixing end and a ground stationary part of a rotating roller on the winch is overcome; the cable conduit ground storage requirement of a down-hole torsion self-balancing cabled drillingtool system is satisfied, the storage space is saved, the storage efficiency is improved, the technical bottleneck in lifting and placing down the cable conduit is overcome, and a technical system ofthe down-hole torsion self-balancing cabled drilling tool system is filled and completed.

Description

technical field [0001] The invention relates to the technical field of drilling and well drilling, in particular to a cable storage and drilling system matched with an underground self-balancing drilling tool system suitable for geological drilling, energy drilling, rescue drilling and the like. Background technique [0002] The surface system is equipped with a self-balancing drilling tool system with double drill bits. The armored cable tube used in the dual-bit self-balancing drilling system has four main functions: one is to establish a drilling fluid circulation channel; the other is to transmit energy for the downhole dual-bit self-balancing drilling system; the third is to bear the weight and The resultant force of friction resistance between it and the hole wall enables it to trip smoothly; Fourth, it can transmit the data collected by the drilling tool system to the ground system and the control signals sent from the ground to the actuators of the drilling tool syst...
