Research on Measurement Technology of Moisture Content by Radio Frequency Method Based on Helical Antenna

The antenna is an important part of the radio frequency method to measure the water content. With the continuous development of gas field, the water production of gas wells has shown significant growth trend during the mine of conventional natural gas. Hence there is an urgent need for wet gas water content measurement technology due to the fact that the production measurement of the single well is closely related to the economic interests of the mining party. In this paper, the detection principle of the radio frequency method based on the helical antenna is described to content measurement moisture. Based on the COMSOL simulation platform, the structures suitable for moisture content measurement are constructed, where the moisture content that is at 0–5% has been simulated and tested. Such design should pave for the realization of online non-separated moisture content measurement.
