Oil well optimal control management system and method and pumping unit frequency converting control method

Abstract

The invention discloses an oil well optimal control management system and method and a pumping unit frequency converting control method. A data collecting module of the management system conducts datacollection, an intelligent management module controls running situations of a pumping unit, monitors oil well real-time data and proposes relative control instructions and warns in advance after conducting intelligent analysis on the oil well running situations, a pumping unit frequency converting control module controls the working frequency or start-stop states of the pumping unit, an application platform is a window for showing the oil well optimal control management system in real time, a wireless communication mode is adopted, the oil-well production and running states are monitored in real time, manual inspection is replaced by electronic inspection, the manual cost is reduced, and environmental factor and manual destruction influence is reduced; a big data technology is adopted, the oil field mass data intelligent analysis requirements are met, and the fact that the real-time capability, the accuracy and the comprehensiveness of measurement data all reach 100% is ensured.

Description

technical field [0001] The invention relates to the fields of big data technology and the Internet of Things technology, in particular to an oil well optimization control management system and method, and a pumping unit frequency conversion control method. Background technique [0002] The distribution of underground crude oil in my country's oilfields is uneven, and the distribution of oil wells is relatively scattered. There are several kilometers or even tens of kilometers between some oil wells. Real-time, accuracy, and comprehensiveness. Some data need on-site measurement and manual recording, which is prone to errors and is not conducive to data management. Oil wells need online monitoring devices. [0003] Most oilfields in China have entered the middle and late stages of exploitation, and the oil supply in the oilfield is intermittent. The start, stop and stroke frequency of the pumping unit need to be adjusted in time according to the oil supply situation of the oil ...

AI Technical Summary

Problems solved by technology

[0004] At present, the online measuring instrument for oil well equipment and the start-stop and frequency conversion control device of the pumping unit have the following defects: there are many types of online monitoring equipment, the quantity is large, and the cost is high, which is not conducive to popularization and use; oil wells need to measure many measuring points, The measurement data are isolated from each other, and there is no connection between the data. Massive online measurement data requires a unified management system

Some oilfields in China have begun digital construction. Due to the lack of intelligence in the management system, a large number of manual operations are required, which is not convenient for application. Only alarm signals can be displayed, and specific equipment failures require manual investigation; the start-stop and frequency conversion control of the pumping unit lacks intelligence, and the start-stop time is usually used to control the start-stop of the pumping unit, and the frequency converter is set according to experience Adjustment method, crude oil can not be fully exploited and utilized
