Abstract

The invention relates to a device for automatically adjusting oil discharge capacity of a lifting system. The device comprises a sound wave generation and receiving mechanism (1), a control mechanism (2) and a motor distribution box (3). The sound wave generation and receiving mechanism (1) comprises a sound wave generator (8), an echo receiver (9), a signal processor (10) and a corrector (11). According to the device, a true depth of oil well level can be obtained by means of a pneumatic sound source testing method, and the oil discharge capacity of the lifting system can be automatically adjusted according to the true depth of oil well level; therefore, energy saving and consumption reduction, equipment loss reduction and production efficiency improvement are achieved.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to a device capable of automatically adjusting the oil discharge capacity of a lifting system according to the depth of the liquid surface of an oil well. Background technique [0002] When the pumping well is in normal production, there is a liquid level in the annular space between the tubing and the casing, and this liquid level is called the oil well liquid level. The oil well liquid level can be expressed by the depth from the wellhead, or its position can be expressed by the height from the middle of the oil layer. Oil well liquid level can be divided into killing liquid level, normal liquid level and optimum liquid level. Among them, when the liquid production capacity of the oil well is greater than the discharge capacity of the lifting system, the liquid level will gradually rise. The higher the liquid level, the greater the liquid column pressure, the higher...
