Abstract

Today, the development of the company’s oil and gas assets is complicated by the extraction of products with a high proportion of waterlogging, due to the long history of operation of most fields. When oil and reservoir water move through pipelines and the borehole and mix them together, crushing occurs (this process is called dispersion), resulting in the formation of water-oil emulsions. An emulsion is a mixture of two mutually insoluble liquids, one of which is dispersed in the other in the form of small droplets (globules).

To date, the main methods of combating the formation of water-oil emulsions (VNE), which complicate the production process, is the supply of demulsifying reagents [1]. For effective operation, demulsifiers must have a set of properties, the most important of which is demulsifying activity. However, the currently used demulsifiers have a dosage limit at which the EE is destroyed during transportation, but an intermediate layer accumulates in the oil treatment plant (UPN), reservoirs, which leads to disruption of the oil treatment process in the technological chain “extraction – transportation - processing”, which significantly affects the quality of commercial oil and its cost price.

Thus, the creation of new demulsifying compositions to increase the efficiency of the decomposition process of stable water-oil emulsions remains relevant.

This article describes a method for developing polyoxyalkylene glycol ether additives for demulsifier compositions by a multifactorial experiment and determining the optimal ratios of the initial raw materials used in synthesis, as well as a method for evaluating the demulsifying activity of the obtained compositions in laboratory conditions.
