Abstract

The invention belongs to the technical field of oil exploitation equipment, and discloses an oil pipe protection device which comprises an oil conveying pipe. A protective outer pipe sleeve is installed outside the oil conveying pipe in a sleeving manner, a puncture-resistant layer is embedded into one side of the interior of the protective outer pipe sleeve, and a heat preservation layer is embedded into one side of the exterior of the puncture-resistant layer; and a flame-retardant rubber ring is embedded into one side of the outer portion of the heat preservation layer, pressure sensors are evenly installed at the edge of the outer wall of the flame-retardant rubber ring in a clamped manner, and a fixed inner side ring is fixedly installed at one side of the outer portion of the flame-retardant rubber ring. According to the oil pipe protection device, by means of an electronic wire and the puncture-resistant layer in the protective outer pipe sleeve, plant puncture prevention, heat preservation and water prevention functions can be provided when the oil conveying pipe is pre-buried, meanwhile, when a fire occurs in the oil conveying pipe, the flame-retardant rubber ring can be contracted towards the fixed inner side ring side under the action of high temperature, a fire source is closed, air is blocked, the fire source is extinguished, and the flame-retardant protection function of the oil conveying pipe is realized.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to an oil pipe protection device. Background technique [0002] Oil and gas fields refer to the sum of oil reservoirs, gas reservoirs and oil and gas reservoirs in the same area controlled by a single local structural unit. Petroleum is an important non-renewable resource, which plays an important role in national economic development and social development. In order to collect and transport the exploited oil resources during oil field exploitation, it is necessary to use oil pipelines for transportation. Oil pipelines in the ground are protected. [0003] The existing oil pipe is only protected against corrosion by adding a PE anti-corrosion layer to improve the durability of the oil pipe. However, when the existing oil pipe is in use, it is impossible to close the fire source when a fire occurs inside the oil pipeline. Blocking and extinguishing the fire sourc...
