ntrol has been successfully applied, which can realize the
function of segmented production of horizontal wells. The liquid production, pressure and temperature of each production layer can be
monitored in real time and for a long time, and the flow rate can be adjusted while measuring, which is of great significance to solve the
problem of high water cut in horizontal wells in Bohai oilfield.
