Abstract

The invention discloses a microwave transmission method-based crude oil water content detection device and detection method. The device comprises a microwave signal source; microwave signals generated by the microwave signal source are modulated by a modulator; the modulated microwave signals enter an oil pipe through a transmitting part; after being attenuated by an oil-water mixed liquid in the oil pipe, the microwave signals are received by a receiving part; the receiving part sends the microwave signals containing water content information to a phase-sensitive detector; the phase-sensitive detector outputs a result to a control part; and the control part calculates the water content of crude oil according to the water content information and on the basis of an existing model. According to the microwave transmission method-based crude oil water content detection device and detection method of the invention, flange plates are adopted for connection, and therefore, the detection device is convenient to disassemble, and the water content of the crude oil can be rapidly detected; the real-time on-line monitoring of pressure environment can be realized; and all metering data can be locally displayed. The detection device and detection method have the advantages of simplicity in operation, convenience in display, high measurement precision, wide range, high anti-interference capability and low cost, and has a wide application prospect in the aspect of crude oil water content detection.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of measuring the water content of crude oil, and relates to a detection device and a detection method for the water content of crude oil based on a microwave transmission method. [0003] 【Background technique】 [0004] The water content of crude oil is an important parameter in petroleum exploration and petrochemical industry, and its accurate measurement is related to crude oil recovery, dehydration, gathering and transportation, metering, trade, refining and so on. In oil field production, the water content of crude oil is of great significance to the estimation of original production, the position of oil outlet, the prediction of oil well development life, the management of oil production automation, etc.; In the process of oil production, the real-time and accurate measurement of the water content of oil products is the key to ensure the accuracy of oil product exchange and reception. Therefore...
