Infrasonic wave generator for testing liquid level of oil well

Abstract

The invention discloses an infrasonic wave generator for testing the liquid level of an oil well, which comprises an inner air cylinder assembly, an outer air cylinder assembly, an upper end cover and an air compression device, wherein a guide frame and an outlet drain plug are arranged between the inner air cylinder assembly and the outer air cylinder assembly; the inner air cylinder assembly comprises an air cylinder sleeve; the outer air cylinder assembly comprises an outer air cylinder; the upper end cover is connected to the outside of the outer air cylinder assembly and is provided withan air hole; one end of the inner air cylinder assembly is provided with an upper drain plug, and the other end of the inner air cylinder assembly is also provided with an air hole; the air compression device comprises a pull rod; one end of the pull rod is provided with a piston; the piston is used for sealing the air cylinder sleeve in the inner air cylinder assembly; a compression spring is arranged at the periphery of the pull rod; the piston is elastically connected with the inner side of the outer air cylinder assembly through the compression spring; and the other end of the pull rod isprovided with a handle. In the invention, sound is produced in an air compression mode, and the generator has the advantages of saving the costs of sound bombs and nitrogen and preventing potential safety hazards caused by the explosion of gunpowder in the sound bombs and is environmentally friendly, economical and pollution-free.

Description

technical field [0001] The invention relates to an infrasonic generator, in particular to an infrasonic generator for oil well liquid level testing. Background technique [0002] The test of oil well liquid level depth is an important work in oil field monitoring. The working status of the oil well unit can be judged through the liquid level test data, so as to adjust the working parameters of the pumping unit in time to achieve the purpose of improving efficiency, saving energy and reducing consumption. The liquid surface depth refers to the distance from the liquid surface in the oil well to the wellhead, which is generally tested by the echo method. [0003] Traditional liquid level tests use sonic bombs or the release of compressed nitrogen to generate sound waves. Acoustic bombs and compressed nitrogen tests are expensive, inconvenient to operate, and have potential safety hazards, which are prone to explosions and serious accidents.
