Abstract

The invention belongs to the technical field of instruments, and particularly relates to a moisture content monitoring device and method. An existing online crude oil water content measuring method isgenerally used for measuring the local water content and cannot represent the overall water content condition in a pipeline. The invention provides a moisture content monitoring device which comprises a pipe body, an electrical tomography sensor and a microwave sensor are arranged in the pipe body, the electrical tomography sensor is connected with a signal collecting and processing unit, and themicrowave sensor is connected with the signal collecting and processing unit. Through the combination of the electrical tomography sensor and the microwave sensor, the identification of the gas-liquid manifold flow state in the pipeline is achieved, and the measurement result of the transmission line is enough to represent the overall water content condition in the pipeline.

Description

technical field [0001] The application belongs to the technical field of instrumentation, and in particular relates to a moisture content monitoring device and method. Background technique [0002] The water content of crude oil is an important parameter in oil exploitation and petrochemical industry, and it is the key data in oil field production and oil product trading. If the monitoring of the water content of crude oil is inaccurate, it will directly affect the determination of the oil well water and oil production layer, the estimation of crude oil production, and the prediction of the development life of the oil well. [0003] The early water content measurement of crude oil mainly analyzed the water content of crude oil by sending samples to the laboratory for distillation or centrifugation. However, due to factors such as the method of sampling and testing, the operation is complicated, and the acquisition of data information lags behind, it cannot reflect the water...
