Problems solved by technology

[0003] At present, each oil well is equipped with a medium-frequency electric heating device. It is manually judged when the wax needs to be removed and the medium-frequency electric heating device is started to heat the oil well, and the heating is not continuous. Generally, the medium-frequency electric heating device can be started for about 1 hour. The effect of wax removal, the utilization rate of multiple medium frequency electric heating devices is not high, resulting in a great waste of investment costs

Abstract

The invention discloses an oil well paraffin removal method, device and equipment and a storage medium and belongs to the technical field of oil production engineering. The method comprises the following steps of receiving pressure signals from sensors corresponding to a plurality of oil wells, wherein the pressure signals are used for indicating wax precipitation states of a plurality of oil wells; determining at least one oil well to be subjected to paraffin removal according to the pressure signal; according to the number of the at least one oil well, a target number of heating devices being determined, and the target number being smaller than or equal to the number of the at least one oil well; and controlling the target number of heating devices to heat the at least one oil well. A heating device does not need to be arranged for each oil well, the oil well needing paraffin removal does not need to be manually judged, the heating device does not need to be started for heating, the equipment utilization rate is increased, and the automatic paraffin removal effect is achieved.

Description

technical field [0001] The present application relates to the technical field of oil production engineering, in particular to a method, device, equipment and storage medium for wax removal in oil wells. Background technique [0002] In the oil production system of the oil field, due to the characteristics of high density of oil wells, many oil wells and small spacing between oil wells, low cost of land acquisition and easy management in the emerging oil field wells, intermediate frequency electric heating is basically used for wax removal for oil wells with high wax content. [0003] At present, each oil well is equipped with a medium-frequency electric heating device. It is manually judged when it is necessary to remove wax and start the medium-frequency electric heating device to heat the oil well, and the heating is not continuous. Generally, it can be achieved in about 1 hour after starting the medium-frequency electric heating device. The effect of wax removal, the util...
