(Summary description)Foam acid acidification process is a new type of acidification stimulation technology that is effective for low permeability, low pressure, and water-sensitive formations. Foaming agent and foam stabilizer are added to the conventional acid system, and the foam generator is mixed with nitrogen to form a foam system. At the same time, it has both foam fluid properties and acidification ability. It is especially suitable for multi-layer heterogeneous oil layer acidification, low pressure and low pressure. Acidification of permeating wells and repeated acidification of old wells.
