Study on Damage and Solution of Acidizing Technology in Sandstone Reservoir

Abstract:

According to the acidizing practice of water injection well in recent years, this paper analyzes and summarizes the damage and solution of sandstone reservoir before and during the process of acidification, and secondary damage countermeasures are putted forward to prevent acid rock reaction. Preventing new precipitation forming during the process of acidification is an important aspect to improve the acidizing effect. And through the indoor experiments and field tests in oilfield, it is obvious that the reservoir damage is very complex, generality and difference. Acidification process has very strong pertinence, so it is very important to analyze and understand the reservoir geological characteristics, productivity, dynamic and static production material. Only making the damage of reservoir clear, the appropriate solutions, which can improve the acidizing effect, achieve the purpose of acidification and meet the needs of actual production, can be used. And the solutions of different damages are analyzed and presented.
