Abstract
During an initial phase of the processing cycle, pressure is raised in the bottom hole of the well, the pressure being limited by the hydraulic fracturing pressure of the seam. Pressure in the bottom hole is maintained long enough for a piezometric curve to be determined, the appropriate period being gauged by the flow rate stabilization. After repression, pressure in the bottom hole is rapidly brought down below the formation pressure by opening the annular space and engaging a jet pump (4). As the pressure in th e bottom hole falls below the formation pressure, a hydrodynamic generator (7) is used to create vibrations, resulting in the vibration-movement of the collector by more than 0.1 x the mean diameter of the pore channels and a vibro-acceleration greater than 0.1 x free-fall acceleration. The transmission of pressure pulses from the generator (7) into the bed 'as though through fluid' will increase as the working of the bottom-hole zone progresses; although the depression value will gradually fall, the radius of the the zone covered by the depression and the processing radius simultaneously rise. The proposed method is recommended for the opening up and working of wells, especially wells exploited under difficult conditions, and directional wells. The method is characterized by a high degree of efficiency in working wells exploited under difficult exploitation conditions and by the fact that it facilitates the efficient working of directional wells.
