Method and device for acid exciting of underwell structure layer
A subterranean well formation is acidized to stimulate the production of hydrocarbons by locating a plurality of jet nozzles in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation, pumping a fluid directly into the annulus, pumping a fluid through...

| description | A subterranean well formation is acidized to stimulate the production of hydrocarbons by locating a plurality of jet nozzles in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation, pumping a fluid directly into the annulus, pumping a fluid through the nozzles and into the annulus, controlling the pressure of one of the fluids so that the fluid charges the annulus but does not flow into the formation, controlling the pressure of the other fluid so that it passes from the annulus and into the formation, then increasing the pressure of the one fluid so that it mixes with the other fluid and generates foam before the mixture passes towards the formation, at least one of the fluids including an acid for stimulating the formation. |
