Automatic control system for oil well tipping bucket measurement

Abstract

The invention discloses an automatic control system for oil well tipping bucket measurement, comprising a measuring control cabinet and an upper monitoring computer, wherein a separation umbrella of the measuring control cabinet is provided with a temperature sensor and a liquid level sensor; the temperature sensor and the liquid level sensor are connected to a programmable logical controller (PLC) control system of the measuring control cabinet; the PLC control system is connected with the upper monitoring computer and is used for receiving acquisition information of the temperature sensor and the liquid level sensor; and the upper monitoring computer is used for receiving information sent by the PLC control system. In the invention, the automatic control cabinet is measured to directly realize the existing site measurement and display control, and dynamic parameter monitoring can be remotely transmitted directly through network, so that each parameter in the oil well measurement canbe observed, analyzed, and summarized, thus field signals can be analyzed, monitored and processed conveniently, faults can be found out timely, the maintenance efficiency is improved, losses are reduced, and normal measurement is ensured.

Description

technical field [0001] The invention relates to an electrical control device, in particular to an automatic control system for oil well dump metering. Background technique [0002] At present, the dynamic production data of oil wells is an important basis for reservoir numerical simulation, dynamic analysis, and guidance for the next step of stable production in oil fields, and oil well measurement is an important link in the acquisition of oil well production data. Known oil well production monitoring equipment is usually in the form of a control cabinet after scattered single settings or simple combination. For example, Chinese Patent No. "200920203074.X" discloses a weighing type automatic metering device for crude oil output. Its application date is September 2, 2009, and its authorization announcement date is May 19, 2010. and a microcomputer control system, the outer tank is provided with a crude oil inlet and a natural gas outlet, and a weighing tank and a weighing s...

Problems solved by technology

[0003] However, the existing oil well metering still has the following shortcomings: 1. The function is not perfect, the placement is not standardized, the operation is inconvenient, the monitoring parameters are not accurate, the display is not centralized, and the data cannot be transmitted through the network. There are certain limitations in both metering modes

2. The double-volume separator has a large measurement error for oil wells with high oil-gas ratio, and the metering mode system of the pressurized box is not airtight, causing great safety hazards and serious waste of associated gas resources

3. Manual oil measurement in large tanks is labor-intensive, unsafe, and has large measurement errors

4. Mass flowmeter measurement and turbine flowmeter measurement, the price is high, the error is larger, and it cannot be used in winter

5. Measuring by Gongtu method, large investment, inaccurate, unreliable, automatic management is too complicated
