Description

Technical Field

[0001] The utility model relates to the technical field of oil exploitation, in particular to a sand-proof pipeline used for oil exploitation. Background Art

[0002] After the oil is mined, it needs to be transported through pipelines. The mined oil contains sand and gravel, so the oil needs to be filtered. For example, a sand prevention pipe (patent number: CN202022187270.1) disclosed in Chinese patent literature filters the transported oil and cleans the filtered sand and gravel by pushing the sand block with an electric push rod. The gap between the sand block and the outer filter tube makes it difficult to clean smaller particles of sand and gravel. In addition, the filter layer of the oil filter is impacted by the sand and gravel during the oil transportation process, causing wear to the filter layer, and regular maintenance and replacement are required.

[0003] To this end, we propose a sand control pipe for oil production. Utility Model Content

[0004] The purpose of the utility model is to provide a sand-proof pipeline for oil production to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a sand control pipeline for oil extraction, comprising an oil inlet pipe, an oil outlet pipe and a U-shaped pipe, wherein both ends of the U-shaped pipe are provided with a first connecting plate, the right ends of the oil inlet pipe and the oil outlet pipe are provided with a second connecting plate, the first connecting plate and the second connecting plate are provided with through holes, bolts are provided in the through holes, nuts are provided on the bolts, a filter tube is provided at the lower part of the U-shaped tube, a mounting port is provided at the left end of the lower part of the U-shaped tube, a slide groove is provided on the inner wall of the filter tube, a spring is provided in the filter tube, a first fixing ring and a second fixing ring are provided in the slide groove, a first filter screen is provided in the middle of the first fixing ring, a second filter screen is provided in the middle of the second fixing ring, and a connecting rod is provided between the first fixing ring and the second fixing ring.

[0006] Preferably, the left end of the filter tube extends up and down, and the extended portion cooperates with the installation port.

[0007] Preferably, the first filter screen and the second filter screen are both arranged obliquely, and the diameter of the filter holes of the first filter screen is larger than the diameter of the filter holes of the second filter screen.

[0008] Preferably, the right end of the spring is fixedly connected to the right inner wall of the slide groove.

[0009] Preferably, valves are provided on both the oil inlet pipe and the oil outlet pipe.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The first filter screen filters the oil and removes the sand and gravel in the oil. The second filter screen performs secondary filtering on the oil and completely removes the sand and gravel contained in the oil. The sand and gravel in the oil impact the first filter screen. The spring arranged on the right side of the second fixed ring buffers the first fixed ring and the second fixed ring. When the sand and gravel impact the first filter screen, the first filter screen is buffered to avoid the sand and gravel directly hitting the first filter screen, thereby increasing the service life of the first filter screen.

[0012] 2. Remove the bolts, remove the U-shaped tube, move the filter tube to the left, quickly disassemble the filter tube, clean or replace the filter tube, move the filter tube, install the filter tube into the U-shaped tube, match the left end of the filter tube with the installation port, quickly install the filter tube, and facilitate quick cleaning or replacement of the filter tube.
