Shallow sea pile foundation concrete oil drilling and producing platform

Abstract

The invention relates to a shallow sea pile foundation concrete oil drilling and producing platform. A pile group foundation is composed of a steel pipe pile group structure or a concrete pile group structure arranged in a rectangular array; a deck chunk is composed of a bearing platform, a deck beam, a deck girder, a deck stringer and a platform deck; the bearing platform is arranged on the top end of each pile; the deck beam is arranged on the bearing platform, and is transversely connected with each pile; the deck girder is arranged on the bearing platform, and is lengthwise connected with each pile; the deck beam and the deck girder are mutually vertical, and form a latticed frame structure in a staggered mode; the deck stringer is arranged between two adjacent piles on the deck beam, and is parallel to the deck girder and vertical to the beam; the platform deck is arranged on a latticed frame structure formed by the deck beam, the deck girder and the deck stringer; and a deck chunk component has a reinforced concrete structure. The area of the platform deck is selected according to the requirement of oil drilling and production, so that a large amount of steel is saved, and the investment cost is reduced; therefore, the platform is suitable for the oil drilling and production in a shallow sea area with the water depth of 3 to 10 meters.

Description

technical field [0001] The invention relates to an ocean platform, in particular to a structure type of a shallow sea oil drilling platform. Background technique [0002] In my country's shoal and shallow sea oilfields, it is effective to build roads and islands in areas with shallow water depth on the sea chart. However, as the water depth increases, the amount of sand and gravel used in the construction of long-distance access roads and artificial islands will increase exponentially, and the cost will of course also increase exponentially. Moreover, it has a huge impact on the marine environment due to the obstruction of water flow due to its underlying foundation. In addition, the State Oceanic Administration of China recently stipulated that in principle, the construction of artificial islands is prohibited in waters with a water depth exceeding 3.0m on charts. If the traditional gravity type or jacket integrated drilling and production platform is used, there are also...

Problems solved by technology

If the traditional gravity type or jacket integrated drilling and production platform is used, there are also disadvantages such as large investment, small platform operating area, and high maintenance costs.
