Description

Technical Field

[0001] The invention relates to the technical field of oil production pipes, in particular to an oil production pipe with a conveying structure and a dredging method. Background Art

[0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid, known as the "blood of industry". Petroleum is stored in some areas of the upper crust. The main component is a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petroleum is made into fuel and gasoline through oil pipelines. It is also the raw material for many chemical industrial products, such as solutions, fertilizers, pesticides, and plastics. The production tubing used in oil production projects is the main part of the oil production machinery system. The tubing can lift the crude oil in the oil well to the ground. It is mainly composed of sucker rods, production pipes, standard oil pumps, screens and wire plugs. The sucker rod is used to transmit the reciprocating motion of the pumping unit to the standard oil pump, so that the piston reciprocates to increase the energy of the well fluid in the wellbore, and the well fluid is lifted to the ground through the production pipe.

[0003] The crude oil extracted from underground is mixed with a large amount of sediment.

At the same time, the wedge-shaped sealing plate (43) is pushed to move to the inside of the mud storage frame (32) through the push rod (42), and the feed port of the mud storage frame (32) is opened, so that the mud slides into the inside of the mud storage frame (32) through the sand guide groove (34); Step 2: After the installation frame (38) moves to the inner cavity of the connecting pipe (31), the push plate (46) and the hinge plate (47) are all in the inner cavity of the connecting pipe (31), and the hydraulic cylinder (35) pushes the hinge rod (37) to push the slider (45) to slide in the inner cavity of the slide groove (44), and pushes the push plate (46) and the hinge plate (47) out of the interior of the installation frame (38), and the hinge plate (47) is driven to rotate and open by the torsion spring (49), and the hydraulic cylinder (35) is started to drive the installation plate (36) to reset and drag the slider (45) and the push plate (46) to reset, so that the mud and sand around the side of the sand guide groove (34) are dragged into the inner cavity of the sand guide groove (34) and introduced into the interior of the mud storage frame (32) through the hinge plate (47), and the work of this step is repeated to clean the blocked mud and sand; Step 3: After the mud and sand are cleaned, the hydraulic cylinder (35) is started to drive the mounting plate (36) to reset, thereby driving the push plate (46) and the hinge plate (47) to enter the inner cavity of the mounting frame (38), and then driving the mounting frame (38) to move upward into the interior of the housing (33) to reset, driving the wedge-shaped sealing plate (43) to block and seal the feed port of the mud storage frame (32), starting the motor (39) to drive the rotating blade (41) to rotate to continue the conveying work, and then opening the sealing door (50) to clean the mud and sand in the inner cavity of the mud storage frame (32).
