RX-203酸化压裂用缓蚀剂

RX-203 for Acidization FracturingCorrosion inhibitor

1. Product Introduction

The acids commonly used in routine acid treatment include hydrochloric acid, phosphoric acid, acetic acid, formic acid, etc. A large amount of acid is injected into the oil well, where the acid dissolves the rock layers and cracks underground, causing the oil and gas fractures and channels to expand. This process aims to bring the oil well into production, increase production, and maintain stable output. Generally, hydrochloric acid is sufficient to achieve good results in the acidification of carbonate rock reservoirs. The treatment of sandstone formations is much more complex than that of carbonate formations. For sandstone oil reservoirs, muriatic acid is used.HCl + HF) is the main factor. The corrosion inhibitors used in soil acid acidification construction must conform to the characteristics of soil acid. Firstly, due to the action of certain factors, their dispersibility is different from that of hydrochloric acid, making them prone to precipitation or stratification. Secondly, their protective effect on steel is not significant. After the reaction, the corrosion inhibitors form lumps, remaining free in the liquid. Thirdly, the mechanism of action of the corrosion inhibitors is different from that of simple hydrochloric acid or.

Based on the above application background, our company has developedRX-203Hydrochloric acid, soil acid acid corrosion inhibitor, this product is mainly composed of oxazole and heterocyclic compounds. It forms a protective film by directed adsorption on the metal surface, and can also inhibit the electrode reaction between acid and metal. It is suitable for various corrosive media, unidirectional corrosion caused by ions, and comprehensive corrosion environments resulting from the interaction of multiple elements. It has good anti-corrosion, corrosion inhibition, and corrosion slowing effects in corrosive environments with high concentrations of hydrochloric acid and soil acid.
