Introduction
The drilling environment has extremely strong corrosive effects on metal equipment, mainly due to the following factors: 1) Drilling fluid contains chloride ions, hydrogen ions, dissolved oxygen, etc., which will accelerate the electrochemical corrosion of steel materials such as drill pipes and casing. 2) The high temperature and high-pressure conditions in deep wells will accelerate the corrosion reaction rate, and common protective measures will fail quickly. 3) Mechanical vibration and erosion during the drilling process will damage the natural oxide film on the metal surface, leading to intensified corrosion. Phosphate corrosion inhibitors are mainly used to inhibit the corrosion of drilling equipment, wellbore, and pipe materials in complex drilling fluid environments. our High temperature corrosion inhibitor can specifically solve the above corrosion problems, and its advantages are significant. the HT acidizing corrosion inhibitor composed of quaternary amine salt and other synergistic substances and surfactants, etc. it has good dispersion in hydrochloric acid medium and can be used in acidizing and fracturing projects in high temperature deep wells with 20% concentration of hydrochloric acid environment. the HT corrosion inhibitor has good acid dissolution performance and high corrosion inhibition rate, and can also reduce the acid corrosion rate of common oilfield pipelines (including continuous oil pipelines), which can effectively protect oil casing and construction equipment and prevent excessive iron ions from entering the formation and affecting the effect of acidizing transformation.
