Oil exploitation pipeline

Abstract

The invention relates to the technical field of oil exploitation equipment, in particular to an oil exploitation pipeline. The oil exploitation pipeline comprises an oil conveying pipeline; the outersurface of the oil conveying pipeline is provided with a polyurethane heat insulating layer; the outer surface of the polyurethane heat insulating layer is provided with a fireproof coating; the outersurface of the fireproof coating is provided with a pressure sensor layer; the outer surface of the pressure sensor layer is provided with a pipe sleeve; the pressure sensor layer comprises a plurality of piezoelectric ceramics which are uniformly distributed; a plurality of temperature sensors are uniformly arranged inside the polyurethane heat insulating layer and in the length direction of theoil conveying pipeline; and the inner wall of the oil conveying pipeline is axially provided with two flow guide ribs which are arranged in a manner of just facing to each other. The oil exploitationpipeline provided by the invention has the advantages that the oil conveying pipeline has a heat preservation function; an ineffective position can be found and recovered when the heat insulating layer loses efficacy; the oil exploitation pipeline has the functions of fire prevention, pressure resistance, filtration and flow guidance; when the oil inside an inner layer is blocked, a sensor in thepressure sensor layer is used for transforming a pressure change signal into an electric signal and sending the signal to an operator for recovery, so safety and reliability are realized.

Description

technical field [0001] The invention relates to the technical field of oil extraction equipment, and specifically discloses an oil extraction pipeline. Background technique [0002] In the field of oil extraction, pipelines are a kind of equipment that must be used. At present, the pipelines used in oil fields are easily corroded by oil and have a short service life. At the same time, the insulation effect of the pipeline is poor, and the heat loss of the pipeline is serious. When the temperature of the pipeline drops, the flow resistance of the oil in the pipeline will increase greatly, which will affect the transportation effect of oil. , At the same time, when the insulation layer of the oil pipeline fails, it is often impossible to timely and effectively determine the location of the failure and repair it, resulting in unnecessary losses, and the extracted oil contains many impurities, which will affect the subsequent oil refining.
