Novel Spar deep sea oil-exploration and oil-extraction engineering platform

Abstract

The invention provides a novel Spar deep sea oil-exploration and oil-extraction engineering platform which respectively has oil-exploration and oil-extraction functions, wherein an exploration platform adopts a 360-degree full-rotation contra-rotating propeller (or serial propeller) power positioning and propelling device and an oil-extraction platform is provided with a mooring rope, so that an efficient, energy-saving and flexible Spar scheme is provided. The gravity center of a Spar platform is designed to be far lower than a floating center and is unconditionally stable so that a hundred-year mega storm can be resisted and impacted. The arrangement of a drilling rod and a marine riser is compact and novel so as to conveniently operate a mechanical hand of a hydraulic crane; the drilling rod and the marine riser are conveyed into the center of a wellhead through an eccentric wheel of a hydraulic rotary mechanism to be put down and be connected in a butted joint manner, and are automatically controlled by a central control room. The Spar platform is controlled by double wellheads and double valves; and a sea floor wellhead and a seabed marine riser are tightly sealed so as to effectively prevent seawater from entering and preventing oil from being leaked. The oil is convenient to extract and the cost is reduced. A cylindrical structure has double layers so that the strength is high and the work of a central well is effectively protected to be safe and reliable. The total level of the novel Spar deep sea platform is higher than traditional platforms at home and abroad.

Description

technical field [0001] The present invention relates to deep-sea oil and gas exploration and oil production engineering, in particular to a world-advanced new Spar deep-sea oil exploration and oil production engineering platform independently developed by my country and equipped with exploration and oil production functions. [0002] 1. The present invention is different from the traditional platform of the same kind. The Spar platform is divided into exploration and oil production, and has different design schemes. The exploration platform moves frequently, so the bottom of the platform is submerged in the water, and the propeller dynamic positioning propulsion device is installed below, eliminating the mooring device, thus integrating self-propelled, towing and positioning, reducing the cost and construction difficulty, and improving the flexibility of Spar sex. [0003] The oil production platform works in one place for a long time, which can reach about 15 years. If the p...

Problems solved by technology

Not only that, the length and arrangement of the drill pipes on the traditional Spar platform are not reasonable, the work efficiency needs to be improved, and the sealing of the underwater oil production device needs to be improved, such as ConocoPhillips’ Bohai Bay spill accident and the BP oil spill accident in the Gulf of Mexico.
