Submarine sediment stratum space drilling robot

Abstract

The invention relates to a soil drilling robot, and aims to provide a submarine sediment stratum space drilling robot. The submarine sediment stratum space drilling robot comprises a lateral mud discharge drill bit mechanism composed of a drill bit and a transmission system, a front excavation supporting body section and a rear excavation supporting body section which are arranged along the axis, wherein the lateral mud discharge drill bit mechanism is located at the front end of the front excavation supporting body section, and a tail oil cable connector is arranged at the tail end of the rear excavation support body section. A front excavating propelling body section comprises an outer barrel, a hydraulic cylinder is arranged in the outer barrel, and the operation mode of telescopic claws can be changed through cooperation of the attraction effect of electromagnets and connecting flanges and a push rod of the hydraulic cylinder. The rear excavation supporting body section is provided with structural components which are the same as the front excavation propelling body section but arranged oppositely in the axis direction, and push rods and telescopic claws of the rear excavation supporting body section and the front excavation propelling body section have opposite action directions. According to the submarine sediment stratum space drilling robot, the body sections are independent in function, and the excavating propelling body sections can be increased according to specific working conditions so as to improve the movement capacity; and by means of the innovative excavating mode, soil around the robot can be squeezed backwards, pushed and excavated.

Description

technical field [0001] The invention relates to a soil drilling robot, in particular to a drilling robot used for seabed sediment formations. Background technique [0002] With the gradual depletion of non-renewable resources on land, the exploration and development of resources such as natural gas hydrates and manganese nodules, deep-sea oil and gas, and hydrothermal deposits, which are rich in seabed reserves, have become the focus. The South my country Sea is rich in natural gas hydrate resources. Currently, the proven natural gas hydrate reserves in the South China Sea reach 70 billion tons of oil equivalent, which is equivalent to half of my country's total proven oil and gas resources. At present, the exploration of seabed natural gas hydrate resources in my country has entered the stage of detailed investigation and trial production. In order to meet the urgent need for improved detection capabilities and accuracy in terms of the spatial distribution of seabed hydrate...

Problems solved by technology

However, the logging equipment mainly relies on lowering while drilling, and its measurement depth and measurement range are completely dependent on the implementation of ocean drilling

After years of development, although the technology of ocean drilling has achieved relatively mature development, its limitations are also more prominent, such as the drilling direction can only be perpendicular to the seabed plane, and generally only one hole can be drilled in a single trip
