Abstract

The invention relates to the technical field of petroleum pipelines, and discloses a petroleum pipeline for deep wells. The petroleum pipeline for the deep wells comprises a first connecting pipe, a first flange is fixedly mounted on the right side of the first connecting pipe, the right side of the first flange is provided with a through hole extending into the connecting pipe, a groove formed inside the first flange is fixedly mounted on the inner wall of the through hole, a telescopic spring is fixedly mounted inside the groove, and an extending pipe extending to the exterior of the first flange is movably installed inside the through hole. By means of the petroleum pipeline for the deep wells, a sealing ring is installed on the inner wall of the through hole, the sealing ring is provided with a sealing gasket, a second flange is provided with a contact ring corresponding to the sealing gasket, and the aim of being good in sealing effect of the petroleum pipeline is achieved; and athreaded rod is installed on a fixing block, a pressing block is in threaded connection to the threaded rod, the contact ring can be in tight fit with the sealing gasket, and the aim of preventing petroleum leakage is achieved.

Description

technical field [0001] The invention relates to the technical field of oil pipelines, in particular to an oil pipeline for deep wells. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as "industrial blood". There are oil reserves in some areas of the upper crust, and the main components are various alkanes, naphthenes and aromatic hydrocarbons Oil pipelines, also called pipelines or pipelines, are composed of oil pipes and their accessories, and are equipped with corresponding oil pump units according to the needs of the process, designed and installed as a complete pipeline system for completing oil loading and unloading and transfer tasks. [0003] With the development of society, the amount of oil extraction is gradually increasing, and the oil pipeline plays an important role in transporting oil, but the sealing effect of the joints between the existing oil pipelines is poor, and oil leakag...
