Abstract

The invention relates to an automatic infrasonic wave non-pressure oil well liquid level monitoring instrument. A gas storage chamber, a gas chamber pressure sensor, a gas emission device, an infrasonic wave receiving and processing device and a gas-collecting device are arranged in a shell of the monitoring instrument; the gas chamber pressure sensor is connected with the gas storage chamber; the monitoring instrument is also provided with a gas generation device; a gas inlet of the gas generation device is connected with the gas-collecting device through a pipeline; and a gas outlet of the gas generation device is connected with the gas storage chamber through a pipeline. The automatic infrasonic wave non-pressure oil well liquid level monitoring instrument extracts gas from an oil well sleeve, and pressurizes and injects the gas into the gas storage chamber to generate an infrasonic wave pulse required by the measured liquid level; and gunpowder sound bombs or nitrogen cylinders are replaced, so that the automatic infrasonic wave non-pressure oil well liquid level monitoring instrument can work on the non-pressure oil well for a long time automatically, continuously and stably.

Description

technical field [0001] The invention relates to a monitoring device for automatically monitoring the liquid level depth of an unpressurized oil well by using infrasonic waves, which belongs to the technical field of oil production engineering and is mainly applied to oil wells without casing pressure in oil fields. Background technique [0002] In the process of oil production in oil field, it is an important work to test the recovery of oil well liquid level. It is necessary to repeatedly measure the annulus liquid level depth of the pumping well at a certain time interval within one day or several days. [0003] As my country's major oilfields have entered the middle and late stages of production, the liquid supply capacity of formations has gradually declined, and there are more and more oil wells without associated gas (ie, unpressurized oil wells). Devices and equipment that can automatically monitor such unpressurized oil wells for a long time are currently available. ...
