Embodiment Construction

[0008] The specific embodiment of the present invention is described in detail in conjunction with accompanying drawing and technical scheme, during use, at first control handle 22 is rotated 90 degrees clockwise, and control handle 22 is turned to the direction perpendicular to the axial direction of outer sleeve 4, to ensure The ball valve 19 keeps the left end of the pressure chamber a in a sealed state, then unscrew the gas tank control valve 27 on the high-pressure gas tank 28 filled with argon, the gas is output through the rubber tube 26, and the control valve 25 is opened, while observing the pressure gauge 1 When the above value reaches the required rated pressure value of 3Mpa, close the gas tank control valve 27 and the input control valve 25 on the high pressure gas tank 28, and stop delivering high pressure gas to the pressure chamber a. At this time, hold the handle 23 and pull Move the handle 22 to the direction parallel to the outer sleeve 4, see the attached f...

Abstract

The invention discloses a sound-producing device for measuring oil well liquid level depth, which belongs to the field of liquid level depth measuring devices. The invention particularly relates to the sound-producing device for measuring the oil well liquid level depth. The sound-producing device is gun-shaped; a handle is arranged below an outer sleeve of the sound-producing device; an air pipe is arranged in the handle; and one end of the air pipe is communicated with a pressure chamber of a rear end inner sleeve, while the other end of is connected with an input control valve. A right upper connecting platform, a right lower connecting platform, a left upper connecting platform and a left lower connecting platform are symmetrically milled on the left part and the right part of a top circle of the front end of the outer sleeve; a hook arranged below the front end of the outer sleeve is connected with a left upper linking arm and a left lower linking arm through lower pins; the front part of the hook is provided with a groove which is connected with a pivot lug welded at the lower end of a front gland; a rubber gasket is arranged in a ring groove of an inner hole of the front gland; and the middle part of the outer sleeve is provided with a ball valve. The sound-producing device has a simple structure, is easy for on-site operation and equipment management, is convenient to carry and convenient to use, and is suitable for field operation. A gas adopted by the sound-producing device causes no pollution to the atmospheric environment and is safe to use.

Description

technical field [0001] The invention belongs to the field of liquid level depth measurement devices, in particular to a generation device for oil well liquid level depth measurement. Background technique [0002] At present, in the process of oil production in the oil field, in order to be able to dynamically manage the oil well and understand the liquid production capacity of the oil layer, the staff must regularly test the liquid level depth of the oil well to obtain the value of the liquid level depth of the oil well, and use this as a basis Reasonable management of oil wells and pumping equipment. At present, the widely used instrument for measuring the depth of the oil well liquid level is to use the gunpowder acoustic elastic wellhead device, and rely on the principle of sound wave reflection to obtain the desired depth value. The gunpowder sound-bomb measurement method needs to carry sounding guns, bullets and testers, which is inconvenient to use. In addition, the f...
