Pump efficiency adjustment oilfield intelligent management system

Abstract

The invention provides an oilfield intelligent management system for adjusting pump efficiency, which is used for administrators to manage the corresponding oil pumping units arranged at a plurality of oil wells in the oilfield. at least one pumping unit control cabinet corresponding to the pumping unit, which is set at the oil well and connected to the pumping unit, operated by the workers, and used to control the pumping action of the pumping unit; the administrator terminal, which is controlled by the management and the management server, which are respectively connected with the oil pumping unit control cabinet and the administrator terminal. Among them, the pumping unit control cabinet has a parameter storage part, a pumping unit information storage part, a control cabinet screen storage part, a control cabinet input display part, a reference dynamometer generation part, a measurement part, a current dynamometer generation part, a comparison A determination part, a frequency conversion part, an adjustment frequency generation part, a control cabinet communication part, and a control cabinet control part.

Description

technical field [0001] The invention relates to an oilfield management system, in particular to an oilfield intelligent management system for adjusting pump efficiency. Background technique [0002] Oil is the most important strategic resource in the current period. In the process of oil extraction, factors such as wear and tear of pumping unit equipment, failures, changes in geological conditions, and the impact of real-time water injection on oil production conditions will continue to affect the oil production process. [0003] Due to the characteristics of oil exploitation, the administrator of the oil field cannot know the real-time status of the oil pump at each oil well in real time. The status information of each oil pump in the oil field needs to be discovered by the management personnel through the change of the liquid production volume measured regularly by the workers. In the current stage of oil well production, the modification of oil production strategies of o...

Problems solved by technology

However, this method can only manually change the stroke times of the pumping unit, which increases the workload of the workers. Moreover, due to the complex and changeable situation in the oil well, the workers in the oil field cannot grasp the situation in the oil well in time, and cannot set the maximum value in time. The optimal control frequency is adapted to the situation in the oil well, so that the average efficiency of the oil pump is low, and the power consumption per unit output is high, which does not meet the current purpose of saving energy and reducing consumption of the oil well.
