摘要： A method is described for recovery of a hydrocarbon fluid from a porous medium by injection of a fluid into the porous medium. The method comprises determining a Rayleigh time on the basis of the density of the fluid and the hydrocarbon fluid, the median pore diameter of the porous medium, and surface tension between the fluid and the hydrocarbon fluid. Further, pressure stimulation is provided in the fluid and generated by a collision process with a collision contact rise time which is of the range of 1-100 times the Rayleigh time. Alternatively or additionally, the providing a pressure stimulation in the fluid include generating an impact pressure with a pressure amplitude I and a pressure rise time Δ t , where the pressure amplitude is larger than the relation γcΔ t /a 2 , where γ is the surface tension between the fluid and the hydrocarbon fluid, and c is the speed of sound in the porous media. In aspects of the invention, the method comprises arranging a chamber in fluid communication with the porous medium via at least one conduit, and having the chamber comprising first and second wall parts movable relative to each other. The pressure stimulation comprises providing an impact pressure in the fluid to propagate to the porous medium via the conduit, and where the impact pressure is generated by the collision process between an object arranged outside of the fluid and the first wall parts for the first wall part to impact on the fluid in the chamber.

摘要： A method is described for the recovery of hydrocarbon from a reservoir. The method comprises arranging a chamber in fluid communication with the reservoir via at least one conduit, and having the chamber comprising first and second wall parts movable relative to each other. An impact pressure is provided in the fluid to propagate to the reservoir via the conduit, where the impact pressure is generated by a collision process between an object arranged outside of the fluid and the first wall parts for the first wall part to impact on the fluid in the chamber. Further, the chamber is arranged to avoid a build-up of gas-inclusions where the first wall part impacts on the fluid. This may be obtained by arranging the conduit in or adjacent to the zone where the gas-inclusions naturally gather by influence of the gravitational forces, or by placing the first wall part impacting on the fluid away from this zone. The invention further relates to a system for the generation of impact pressure as mentioned above.
