Abstract

The invention relates to the technical field of dynamic testing of oil wells in the petroleum industry, in particular to a multi-sensor fusion measurement system for measuring water content and / or salinity. The output of the programmable oscillator (X1) is connected to the multiplexer (X2), the multiplexer (X2) is connected to the coupler (X5) for communication, and the coupler (X5) is connected to the digital phase shifter (X6) for communication. The phase shifter (X6) communicates with the phase difference detector (X7); the output of the programmable oscillator (X1) is connected to the multi-channel signal distributor (X2) to generate multiple high-frequency signals of the same frequency, amplitude and phase; first take one of the channels After the high-frequency signal enters the coupler (X5), two signals are output, which is the water content measurement part; secondly, two high-frequency signals are taken, which is the salinity measurement part.

Description

technical field [0001] The invention relates to the technical field of dynamic testing of oil wells in the petroleum industry, in particular to a multi-sensor fusion measurement system for measuring water content and / or salinity. Background technique [0002] Existing oil well wellhead multi-parameter measurement technology (mainly independent sensors): [0003] At present, there is no measuring instrument in China that can simultaneously test the water content, temperature, and pressure of the wellhead of the oil production well. It is mainly measured by independent sensors. The existing technology leads to high production costs and complicated on-site processes, which is not conducive to production management. [0004] In terms of moisture content measurement: generally divided into two types, namely manual measurement method and online measurement method. Most of them use manual sampling measurement method, which can be divided into distillation method, electric strippin...
