Oil storage tank optical fiber liquid level intelligent monitoring system

Abstract

The invention relates to the technical field of oil storage tank liquid level monitoring, and discloses an oil storage tank optical fiber liquid level intelligent monitoring system, which comprises a plurality of groups of liquid level sensors arranged on the outer wall of an oil storage tank, each group of the liquid level sensors is formed by combining a strain sensor S1 and a strain sensor S2, the vertical installation distance between the strain sensor S1 and the strain sensor S2 is h0, The multiple groups of liquid level sensors are connected with a collector, the collector is connected with a controller host, the controller host is connected with a monitoring center, and the monitoring center is connected with a server and a far-end platform. According to the invention, the multiple liquid level sensors are arranged, the measurement precision and reliability are greatly improved, a traditional method adopting manual scale detection and assay analysis is changed through the oil storage tank liquid level and temperature on-line monitoring system, real-time dynamic monitoring of oil is achieved, a data basis is provided for production management decisions, and safety accidents are avoided.

Description

technical field [0001] The patent of the present invention relates to the technical field of oil storage tank liquid level monitoring, and specifically relates to an optical fiber liquid level intelligent monitoring system for oil storage tanks. Background technique [0002] my country is rich in petroleum resources. In recent years, the petroleum industry has developed rapidly, and there are many oil extraction and refining enterprises. Therefore, accurate measurement of oil storage tank data has a significant impact on oil production, tank farm inventory and oilfield management. The oil storage tank parameter management and analysis system can conduct real-time statistical analysis on the changes of liquid level and temperature in the oil storage tank, so that users can manage the production dynamics of oil wells in a timely and accurate manner, and make oilfield management change from inefficient manual management to automatic management. [0003] Oil storage tanks are im...

Problems solved by technology

[0005] The purpose of the present invention is to provide an intelligent optical fiber liquid level monitoring system for oil storage tanks. Multiple liquid level sensors are arranged to greatly improve the measurement accuracy and reliability. The method of analysis realizes real-time dynamic monitoring of oil, provides data basis for production management decision-making, and avoids the occurrence of safety accidents. When measuring the liquid level, it is necessary to reach the top of the oil storage tank for operation, which makes the measurement operation inconvenient
