Acid treatment process for the formation of acid fracturing process is called the fracturing and acidification in the pressure of the formation of the formation of the formation of cracks or open formation under the pressure of the original fracture. Can be divided into pre - liquid acid pressure and ordinary acid pressure (or general acid pressure). Fracturing and acidification is mainly used for oil and gas wells with deep or low permeability zone. The acid fracturing pressure is higher than that of the oil (gas) layer, and the people are used to call it. Acidification hydraulic pressure is a widely adopted measure of increasing oil production and injection in the oil field of the oil field at home and abroad. Has now begun to become an important means of completion.
