Permanent Downhole Pressure Gauges

SITAN YJL-200 permanent downhole pressure gauge is mainly used to produce development well and drain and collect for CBM. SITAN YJL-200 permanent downhole pressure gauge can collect real-time and continuous data of well condition in a surface read out manner, providing data and curve analysis to production command.

The department of production command can monitor the reservoir dynamic in time and adjust the working parameters of oil well pump or electric submersible pump so as to ensure the optimum of yield and recovery efficiency. The working time of SITAN YJL-200 permanent downhole pressure gauge can be over 2 years. The particularity of this system decides that the biggest characteristic of this system is the stability and reliability.
