Submarine jet drilling vehicle

Abstract

A submarine jet drilling vehicle, which belongs to the technical field of energy exploitation, comprises a fixing structure, a jet drilling module, a plurality of propelling modules, a storage and hardening module, a control module and a vehicle body, wherein the propelling modules are symmetrically distributed on the vehicle body and connected with the control module, the control module is arranged in the vehicle body, the fixing structure is connected with the vehicle body, both the jet drilling module and the storage and hardening module are connected with the vehicle body, and the controlmodule is respectively connected with the fixing structure, the storage and hardening module and the jet drilling module. The submarine jet drilling vehicle can be used for continuously, efficiently,safely and reliably exploiting submarine flammable ice strata, and solves problems related to the economy and safety of the exploitation of submarine flammable ice.

Description

technical field [0001] The invention relates to a device in the technical field of energy exploitation, in particular to a submarine jet drilling vehicle. Background technique [0002] Due to the massive consumption of traditional energy sources, energy issues have always been a common concern of the international community. Combustible ice has attracted the attention of various countries with its huge reserves, high-efficiency energy storage rate, and clean combustion, and is generally considered to be the best way to solve the energy crisis. At present, the mining of combustible ice on the seabed still has many economic and safety issues to be solved, and it is still in the stage of demonstration and experiment. At the same time, the development of related equipment required for mining combustible ice is not perfect, especially the drilling devices for mining combustible ice layers on the seabed are very few, and there is no one that can be used for continuous, efficient,...

Problems solved by technology

[0004] After searching the existing technical literature, it was found that the Chinese patent application number is: CN200510048133.7, and the patent name is "High-pressure water jet drill bit capable of hydraulically switching punching and slotting". This structure uses high-pressure water as the power to realize the mine layer drilling, but the drill bit has high working pressure, complex structure and large resistance loss

The Chinese patent application number is: 200820064169.3, which is entitled "a dual-purpose drill bit for drilling and coring for natural gas hydrate". This structure can realize drilling and coring, but gas hydrate is not considered in the drilling process mine security
