Problems solved by technology

[0004] However, due to technical and cost constraints, it is often impossible to run the conduit too deep, resulting in the rapid subsidence of the conduit due to insufficient bearing capacity during subsequent operations, resulting in the failure of normal drilling, completion and production operations. At the same time, it causes a large amount of economic loss and even marine ecological environment pollution.

Abstract

The invention relates to an internal rotation type guide pipe bearing capacity reinforcing device and a using method thereof. The internal rotation type guide pipe bearing capacity reinforcing devicecomprises a reinforcing mechanism and a connecting part, wherein the reinforcing mechanism is provided with a reinforcing body and a reinforcing plate connected to the lower part of the reinforcing body, a plurality of reinforcing rib plates are arranged at intervals in the circumferential direction of the reinforcing body, and the reinforcing rib plates are connected with the reinforcing plate; aplurality of accommodating spaces are arranged in the reinforcing plate at intervals in the circumferential direction of the reinforcing plate, a movable sector plate is separately arranged in each accommodating space, perforated parts are separately arranged at the position, located at the accommodating spaces, of the reinforcing plate, and the sector plates can block the perforated parts; and the connecting part is provided with a male buckle end and a female buckle end, the female buckle end is connected to the upper end of the reinforcing body, and the male buckle end is connected to thelower end of the reinforcing body. According to the internal rotation type guide pipe bearing capacity reinforcing device and the using method thereof, the action area between a riser or a surface layer guide pipe and the seabed soil can be increased, so that the bearing capacity of the guide pipe is increased, and the safety and high efficiency of on-site exploration and development operation isensured.

Description

technical field [0001] The invention relates to the technical field of offshore oil and gas drilling and completion, in particular to an internally rotating conduit bearing capacity enhancing device and a method for using the same. Background technique [0002] As the country intensifies its efforts in oil and gas exploration and development, the areas of oil and gas exploration are gradually shifting from land to offshore shallow water areas and far sea deep water areas. In the future, the focus of oil and gas development will also be on shallow ocean water and deep ocean water areas. [0003] For the drilling, completion and production operations in the shallow water area of ​​the ocean, the water isolation of the riser conduit and the support for the blowout preventer (BOP) or the oil / gas tree on the water are inseparable; while the drilling, completion, and production operations in the deep water area of ​​the ocean The operation is inseparable from the support of the su...
