Automatic Control Research on Water Curtain System of Underground Water Seal Oil Cavern

The operating costs of a large-scale water seal oil cavern are a good deal of expenses. Water curtain can achieve a reasonable distribution of water seepage field to reduce the water inflow into the cavern by optimizing the arrangement of water curtain system. It may be preferred to control water pore pressure of well points dynamically in time based on input parameters entered by user system, natural hydraulic conditions, as well as change in the operation of petroleum breathing. This method is based on the theory of fluid flow closed loop and the critical storage pressure determined by this theory. It is an effective way to adapt water pressure of water curtain system to seasonal change of water level, to increase the safety of oil cavern and to reduce operating costs greatly.
