Problems solved by technology

In the past few years, two-speed motors or multi-speed motors have been applied in various oilfields in my country. However, due to the inaccurate identification technology of pumping wells, how to switch between different operating speeds in time according to the actual needs of oil wells is difficult. Mature, the switching method is mainly done manually, thus limiting the development of this technology

Abstract

The invention discloses a beam-pumping unit automatic optimization operation method based on a multi-winding motor. The beam-pumping unit automatic optimization operation method based on the multi-winding motor can calculate and analyze the oil well annulus submergence depth and the oil well pump filling degree under the condition that a beam-pumping unit does not use any external sensors (a liquid level sensor, a flow sensor, a position sensor, a load sensor, an indicator diagram sensor, a pressure sensor, a motor speed sensor and the like) and under the condition that frequency conversion equipment such as a frequency converter and a servo driver is not used, and automatically adjust the operation speed and the corresponding operation time of the pumping unit to realize the optimization operation of the pumping unit.

Description

technical field [0001] The present application relates to the field of oil recovery technology, in particular to an automatic optimal operation method of a beam pumping unit based on a multi-winding motor. Background technique [0002] The beam pumping unit is a widely used oil production equipment in oil fields. It has been developed for a hundred years. The control system of the early beam pumping unit adopts a non-frequency conversion method. When the production of the oil well changes, the speed of the pumping unit needs to be changed. The method of changing the diameter of the motor pulley to change the transmission ratio has increased the workload and management difficulty of the on-site personnel; in recent years, the large-scale application of frequency converters has made it very simple to change the operating speed of the pumping unit, and the workload and management difficulties of the on-site personnel significantly reduce. However, there are some problems in th...
