An offshore thermal oil steam delivery pipe

Abstract

The invention provides an offshore thermal oil recovery steam transport pipe. A plurality of pipe bodies with connecting caps and threaded joints are connected with one another so as to form the transport pipe. A spherical head is arranged in each connecting cap; a spherical sealing gasket is installed in each threaded joint; a plurality of gas guide thin pipes are connected between the connecting cap and the threaded joint through mobile rings; the outer side of the gas guide thin pipe group is wrapped with a thermal insulation mineral blanket; the outer side of the thermal insulation mineral blanket is wrapped with a steel wire protective net; and the gas guide thin pipes are distributed annularly at intervals. Since the transport pipe of the invention is formed through combining a plurality of thin pipes, the transport pipe can be stressed and deformed with the action of an external force, and the transport pipe can be flexible, so that the pipe can absorb impact of sea waves and normally transport high-temperature and high-pressure steam. The transport pipe can be adaptive to the free bending of a steam transport pipeline. The transport pipe has the advantages of convenient connection, long service life, safety and environmental protection. The transport pipe can be suitable for be applied to offshore thermal oil recovery steam transport pipelines, and is suitable for pipeline compensation and corner-turning application of various kinds of pipelines on the ground.

Description

technical field [0001] The invention provides a steam transmission pipeline in the field of offshore oil production. Specifically, it is an offshore heat recovery oil steam delivery pipe. Background technique [0002] At present, in domestic offshore oil production, the boiler is installed on the boiler ship, and the high-temperature and high-pressure steam is sent to the drilling platform through the connecting pipe to inject gas into the oil well to realize thermal oil recovery. [0003] Since the steam delivery pipe used is a single-chamber straight pipe, it is vulnerable to the impact of waves and the shaking of the hull causes deformation or fracture of the steam delivery pipeline. Therefore, when the straight pipes are connected, the technical problem of pipeline deformation and fracture cannot be solved. Contents of the invention [0004] In order to solve the defect that straight pipes are easy to be damaged, the present invention provides an offshore thermal reco...
