The oil field acidifying process is a process technology which utilizes the chemical reaction between acid liquor pumped into an oil layer and mineral substances or cementing substances in the oil layer to generate soluble substances so as to improve the seepage capability of the oil layer or remove oil layer plugs. The processes can be divided into acid pickling, matrix acidification and fracture acidification (also called acid fracturing). Acid washing is to inject a small amount of acid liquid into a well, remove acid-soluble particles, drill cuttings, scales and the like in a borehole at the head of the well, and dredge the borehole; matrix acidizing is to inject acid into the stratum under the pressure lower than the fracture pressure of rock, and restore or improve the permeability of an oil layer in a larger range near the well by means of the corrosion action of the acid solution; acid fracturing, also known as acid fracturing, is the process of injecting acid into a formation at a pressure higher than the fracture pressure of rock to form fractures in the formation, and forming fractures with high conductivity by non-uniform erosion of acid liquid on the fracture walls.
Acidification is one of the main means for increasing the production of oil and gas wells and increasing the injection of water injection wells, and acid liquor is used for removing the pollution near the bottoms of production wells and water injection wells, removing blocking substances in pores or cracks, or improving the original pores or cracks of the stratum and improving the permeability of the stratum, thereby achieving the purpose of increasing the production and the injection.
