Problems solved by technology

[0002] At present, the oil pipelines used for oil production are all metal pipes, and the metal pipes are connected together through joints according to the depth of the well. Because the metal pipes are heavy and easy to hang wax, they often need maintenance and labor intensity, which affects the service life of the lifting equipment.
In order to overcome the shortcomings of the existing technology, it has been proposed to replace it with a rubber-plastic hose. The production method of this non-metallic tube is to first select the material, determine the inner diameter of the finished product, use the corresponding mold core, and wrap a plastic hose on the mold core. Layer of light film glue, then wrap paper layer, glue layer, lead skin layer or plastic layer or water cloth layer one by one, enter the vulcanization tank for vulcanization, cool after vulcanization, and demould, this traditional production method is only suitable for the production of 40m The rubber hose with the length below cannot produce large-diameter super-long rubber-plastic composite hose. The surface of this pipe has no reinforcement layer and heating layer. Therefore, it is far from meeting the technical requirements of large-diameter super-long anti-wax in oil fields.

example 1

[0023] A heating layer, a first reinforcement layer, a second reinforcement layer and a rubber-plastic outer protective layer are sequentially arranged on the surface of the rubber-plastic alloy hose along the radial direction, and a rubber-plastic alloy rubber layer is arranged between each layer. The heating layer is a silicon rubber sheet with an electric heating element inside. This piece is an electric heating wire or an electric heating sheet, one end of which is electrically connected to form a single-phase circuit or a three-phase circuit and is connected to the power supply. The first reinforcement layer and the second reinforcement layer are copper-plated high-strength steel wire mesh layers with a mesh diameter of 0.35 mm and a mesh weaving angle of 40 degrees. The rubber-plastic composite hose has an inner diameter of 30mm and a length of 800m. The preparation method of this tube comprises the following steps:

Abstract

A large caliber myriametre rubber laminated tubing used for oil recovery and a producing method belong to the rubber hose shaping field. Aiming at the defects that the existing technology only can produce the rubber tube with small caliber and short length and can not used in the oil field, disclosed is a large caliber myriametre rubber laminated tubing and a producing method, wherein the tube which is provided with a mat adding layer along the radius direction on the rubber alloy hose surface. The first and the second reinforced layers and the rubber outer protective layer are provided with rubber alloy sizing layer therebetween in order to increase the adhesion. The producing method of the tube includes preparing the rubber alloy sizing, core free extrusion, making the mat adding layer, the first and the second reinforced layers and the rubber outer protective layer, sulfuration and pressuring check, the obtained products has the caliber of 30-50 mm, the length of 800-2000, which is suitable for the oil field.
