摘要： 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.

摘要翻译：酸化地下井井，以通过将多个喷射喷嘴定位成与地层的壁间隔开的关系，以形成在喷嘴和地层之间的环形空间，将流体直接泵送到环空中，泵送一个流体通过喷嘴进入环形空间，控制一种流体的压力，使得流体对环形进行充气，但不流入地层，控制其他流体的压力，使得其从环形空间进入地层然后增加一个流体的压力，使得其与另一个流体混合并在混合物通向地层之前产生泡沫，至少一个流体包括用于刺激地层的酸。
