Embodiment Construction

[0024] Such as figure 1 As shown, the subsea deep hole drilling rig disclosed in this embodiment includes a drilling rig body and a storage pipe rack that are independent of each other.

[0025] The drilling rig body includes a frame 1 , a drilling system 2 , a mechanical arm 3 , bottom crawlers 4 , and an acoustic system 5 .

[0026] The frame 1 includes a frame body 11 and a base 12 at its lower end, and the front side of the frame body 11 is an open side. The mechanical arm 3 is installed on the base 12 , and the acoustic system 5 is installed on the upper part of the frame 11 .

[0027] The drilling system 2 adopts the same structure as that of the present monolithic drilling rig, and is installed on the vertical line passing the center of gravity of the frame body 11 .

[0028] The mechanical arm 3 is a multi-degree-of-freedom mechanical arm capable of bending and extending forward and backward, pitching up and down, and rotating 360 degrees. The mechanical arm 3 is in...

Abstract

The invention discloses a seabed deep hole drilling machine and an application method thereof. The drilling machine comprises a frame and a pipe storage frame which are mutual independence, a bottom traveling track, a mechanical arm, a drilling system and an acoustic system are mounted on the frame, the pipe storage frame is used for storing drilling rods and / or drilling tools, and the bottom traveling track, the mechanical arm, the drilling system and the acoustic system form a drilling machine body. The pipe storage frame and the drilling machine body are sequentially placed into a sea bed,the drilling machine body searches the pipe storage frame through the drilling machine body, the bottom traveling track runs near the pipe storage frame, the drilling rods and / or drilling tools on thepipe storage frame is transferred to the drilling system by the mechanical arm in the working process, the drilling rods and / or drilling tools are connected by the drilling system to drill and sample, and the recovered drilling rods and / or drilling tools are transferred to the pipe storage frame. The pipe storage frame and the drilling machine body are placed into the sea bed, the weight and thesize of the pipe storage frame and the drilling machine body are greatly reduced, more drilling rods and / or drilling tools can be placed on the pipe storage frame through a take-up and pay-off mechanism supporting a mother ship, and a deep hole is drilled.

Description

technical field [0001] The invention belongs to the field of exploration of marine mineral resources, in particular to a seabed deep hole drilling machine and an application method thereof. Background technique [0002] The submarine drilling rig is an important technical equipment for marine geological and environmental scientific research, marine mineral resource exploration and submarine engineering geological survey. In order to meet the needs of continuous exploration of deep-sea resources scientific research, the drilling depth of seabed core sampling drilling rigs is getting deeper and deeper. Unlike surface drilling rigs, the deployment and recovery of subsea drilling rigs depend on the retractable mechanism that supports the mother ship. [0003] The current subsea drilling rig is a monolithic structure, and their weight and volume are large, and its weight and volume are limited by the optical cable carrying capacity of the retractable mechanism and the A-frame al...
