Studies And Applications Of Acidizing In X Oilfield

Acidizing is a kind stimulation of injecting the acid to the pay zone to dissolve and/or disperse materials that impair well production in sandstones or to create new, unimpaired flow channels between the wellbore and a carbonate formation. The acidizing is widely used in the oil and gas fields, especially in carbonate field. The new technology of acidizing have been well developed in recent years.Acid wash, matrix acidizing and acidizing fracture had been introduced in the paper. Based on the formation characteristic, the pilot acidizing had been implemented in X oilfield. By detail analyzing six cases, the suitable acidizing proposals had been proposed and approved that they were effective..
