Abstract

The invention discloses a drilling coring device and method as well as an offshore floating platform. The offshore floating platform comprises the drilling coring device. The drilling coring device comprises a drilling floor, a derrick, a traveling block, a top drive suspended on the traveling block, a lift winch for lifting and lowering the traveling block and the top drive, a drill rod connectedto the top drive and a coring winch, the traveling block and the top drive each are provided with a central through hole capable of allowing a coring barrel to pass therethrough, the central throughhole of the traveling block and the central through hole of the top drive are concentrically arranged, a steel cable of the coring winch sequentially penetrates through the central through hole of thetraveling block, the central through hole of the top drive and the central through hole of the drill rod from top to bottom, and the tail end, with fishing equipment, of the steel cable goes deep into the bottom end of the drill rod so as to be connected with the coring barrel. According to the drilling coring device and method as well as the offshore floating platform, a large amount of manpowerand labor cost are saved, and the operation capacity and efficiency are improved.

Description

technical field [0001] The invention relates to the fields of ships and ocean engineering, in particular to a drilling and coring device and method thereof, and an offshore floating platform. Background technique [0002] At present, the field of deep-sea scientific research has become the arena of major developed countries, and having deep-sea scientific exploration capabilities is the core and foundation for achieving breakthroughs in deep-sea scientific research. In addition, marine geology and mineral resource information are important basic data for safeguarding marine rights and interests and supporting the formulation of international rules. Seabed geological drilling and coring is the most direct and effective way to obtain information on marine geology and mineral resources. [0003] The current seabed geological drilling coring methods include lifting drill coring and rope coring. Lifting and coring refers to recovering the coring barrel by lifting the drill pipe...
