Embodiment Construction
[0022] The intermittent work control method of the electric submersible plunger pump pumping system provided by the present invention is based on figure 1 The control system shown is realized. The system includes remote central control station, local monitoring, core controller ICU, multiple complete sets of frequency converters and plunger pumps, remote central control station, local monitoring are respectively connected to the core controller ICU, and the core controller ICU is connected to each frequency conversion device connection.
[0023] First, follow the figure 1 The system structure and wiring in the system complete the connection of each device.
[0024] Then, follow these steps:
[0025] 1) The pumping system and the control system are initialized after power-on;
[0026] 2) Through local monitoring or remote central control station, the preset value and stroke setting value N 1 Write into the core controller ICU;
[0027] 3) The core controller calculates th...

The invention belongs to the field of oil pumping units, and particularly relates to an intermittent operation control method for an electric oil-submerged plunger pump oil pumping system. According to the method, the waiting time is calculated based on the required time of each stroke and the running time of one electric oil-submerged plunger pump according to the theory, and accordingly the number of plunger pumps which can be started within the waiting time is calculated. According to the method, through alternate operation of the electric oil-submerged plunger pumps at the intermittent time, the situation that the electric oil-submerged plunger pumps operate randomly is changed, the problem that the electric oil-submerged plunger pumps operate at the same time is completely avoided, and the impact on a power grid of the start current generated when the electric oil-submerged plunger pumps are started at the same time is lowered. Besides, under control, the next electric oil-submerged plunger pump is started when one electric oil-submerged plunger pump conducts intermittent waiting, mutual interference is avoided, and it is guaranteed that all the electric oil-submerged plunger pumps operate stably.
Description
technical field [0001] The invention belongs to the field of pumping units, in particular to an intermittent work control method for an electric submersible plunger pump oil pumping system. Background technique [0002] Traditional pumping units adopt uninterrupted continuous working mode to increase oil output. At present, most oil fields in my country use this method to control the work of pumping units. However, this working method has disadvantages such as large energy consumption, reduced service life of mechanical components, and greater impact from the power grid. Contents of the invention [0003] In order to solve the above-mentioned technical problems existing in the background technology, the present invention provides an electric submersible plunger pump pumping system with high working efficiency, good energy-saving effect, and prolonging the service life of mechanical and electrical equipment. method. [0004] The technical solution of the present inventio...
