ИНГИБИРУЮЩИЙ СОСТАВ ДЛЯ НЕФТЕПРОМЫСЛОВЫХ СРЕД НА ОСНОВЕ ТРЕТИЧНОГО АМИНА И ОТХОДОВ ХЛОРОРГАНИЧЕСКОГО ПРОИЗВОДСТВА

Abstract

In the operation of oil wells of equipment is their contact with highly aggressive media. Drilling, casing, and other metallic equipment used in drilling wells, can be exposed to corrosion. Dissolved gases in the drilling solution, such as oxygen, carbon dioxide and hydrogen sulfide can cause severe corrosion of the equipment, both on the surface and inside the well. Corrosion control can not only extend the life of oil field equipment, but also reduce operating costs for its repair, improve technical and economic indices of production and processing of oil and gas fields. Resource-developed method of producing a corrosion inhibitor based on 1,3-dichloropropene (organochlorine production waste) and triethylamine modified by the addition of boric acid. The optimal conditions for the synthesis of an amine of the process: temperature 85 °C, the synthesis of five hours, the ratio of triethylamine: 1,3-dichloropropene - 1.2 : 1.0. Yield: 96.0% (wt.), structure of the obtained product was confirmed by NMR spectroscopy and determined its chemical structure. There have also been studied physico-chemical properties; determined the optimal dosage of the inhibitor at which the protection level of 95.5 % is achieved; set synergistic effect inhibiting action amine and boric acid. The optimum ratio of the amine and boric acid - 0.075 : 3.75 g/l Evaluation of the effectiveness of the synthesized inhibitors were carried out in an electrochemical and gravimetric model solution produced water. The resulting compound has disinfectant properties and fights biocorrosion.
