Annotation:

The use of available sources of renewable raw materials for the production of chemical reagents used in the process of drilling wells is an urgent task for the construction of wells in the Russian Federation. The paper considers various options for the use of technical raw materials of plant origin as multifunctional reagents of complex action. The main interest is the fat-and-oil fraction (MFF), which is a waste product of the production of surface-active imidazolinium compounds based on fatty acids consisting of methyl esters of various fatty acids. Esters based on fat-and-oil fraction (MFF) and high molecular weight alcohols C4–C12 were obtained in the laboratory of process fluids for drilling and well repair of the REC “Field Chemistry” at Gubkin Russian State University of Oil and Gas (National Research University). The selection of optimal conditions for laboratory syntheses using technical renewable raw materials and alcohols C4–C12 both with and without low-boiling components was carried out. Technological properties of drilling fluids were determined when adding the obtained products and directions for further research were determined.
