Abstract

The paper considers one of the most urgent problems for petroleum industry - buildup of asphaltene-resin-paraffin deposits, which have adverse impact on oil production performance. Particularly, they cause decrease in oil production rates, disrupt transportation of hydrocarbons and accelerate equipment wear, ultimately resulting in higher operating costs and reduced profitability of oil production. The paper presents a detailed analysis of currently available methods for prevention of such deposits, including application of dispersants that help disperse and remove the deposits from the oil flow. Applicable standards for evaluation of dispersants efficiency are considered to allow for identification of their advantages and shortcomings. The paper also reveals the disadvantages of traditional evaluation practices, which often do not provide accurate and reliable data about the dispersive properties of chemicals, thus making the selection of the optimal solution for specific conditions a challenging task. Based on laboratory results, a new method for digitization of test data is proposed to enable more accurate qualitative and quantitative determination of the dispersive properties of chemicals while using lower volume of chemicals and formation water. This innovation not only simplifies the evaluation process, but also reduces the cost of experiments. The present research is aimed at optimization of oil production processes, improvement of the quality of chemicals performance evaluation and ultimately enhancement of the overall efficiency of oil production wells. The research findings can be useful both for oil production engineers and for scientists engaged in the development of new technologies in this field.

Key words:
