Oil pipe connecting device for oil exploration

Abstract

The invention discloses an oil pipe connecting device for oil exploration. The oil pipe connecting device comprises a first oil pipe, a second oil pipe, a limiting ring, fixing mechanisms and a sealing mechanism, wherein each fixing mechanism comprises a moving block, a sliding block, a limiting block, a transverse rod and a connecting rod, and the sealing mechanism comprises a sealing assembly and a limiting assemblies. According to the oil pipe connecting device for oil exploration, the first oil pipe and the second oil pipe are fixed through the fixing mechanisms, the first oil pipe and the second oil pipe are sealed through the sealing mechanism, compared with an existing sealing mechanism, the sealing mechanism abuts against the limiting ring through water bags, so that the limiting ring is sealed, the water bags are inflated through sealing units, the water bags better abut against the limiting ring, the sealing effect is improved, meanwhile, the limiting ring is fixed through limiting assemblies, the limiting ring is prevented from moving, the moving blocks better abut against the limiting blocks through restoring force of second springs, and the use practicability is improved.

Description

technical field [0001] The invention particularly relates to an oil pipe connection device for oil exploration. Background technique [0002] Existing pumping for oil wells is generally connected through oil pipes, and because the depth of oil wells is relatively deep, it is generally connected through two oil pipes to achieve suction inside the oil well. When the problem of oil well blockage occurs , the commonly used method is through negative pressure suction. This method is low in cost and easy to operate, but when using negative pressure suction, it may cause the connection of the two oil pipes to fall off, which brings great harm to the oil production work. the inconvenience. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil pipe connection device for oil exploration in order to overcome the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve the t...
