Abstract
A yield estimation device for a low-yield shale gas reservoir includes: a separation tank, a pulse gas detector, and a methane concentration detector; wherein a liquid inlet is provided at an upper portion of the separation tank; an exhaust pipe is provided on a top of the separation tank, and the pulse gas detector is installed at a middle section of the exhaust pipe; the methane concentration detector is installed at a tail end of the exhaust; a valve is installed in a liquid outlet; a float is arranged in the separation tank, which is connected to the valve through a telescopic float rod. A yield estimation method includes steps of: inputting flowback fluid into the separation tank through the liquid inlet; discharging the air in the separation tank; performing gas-liquid separation; detecting and displaying the shale gas in real time with the pulse gas detector.
