Separation of water-in-oil emulsion is a significant part of the cost of oil production due to the use of expensive demulsifiers and additional heating of the emulsion by burning associated petroleum gas. The article discusses an acoustic method that enables the increasing of the rate of separation of the emulsion. In field conditions, tests were carried out in which the efficiency of separation in the acoustic field was determined depending on the temperature of the product, the concentration of the demulsifier, and the frequency and time of exposure to the emitter. The results obtained allow us to talk about a significant reduction in the consumption of demulsifiers, a decrease in the influence of temperature on the phase separation process and an increase in the efficiency of oil treatment at existing facilities.

Currently, a global attention has been paid to the development and exploitation of shallow depth heavy oil reservoirs. Such oilfields are rationally developed via a network of horizontal wells. However, the weakly cemented reservoir rock beds lead to the high sand production during well flow. Removing mechanical impurities is still challenging even with the application of sophisticated techniques and a variety of filters. In this study, we propose an analysis method for describing the removal of mechanical impurity particles from horizontal wells containing heavy oil. We employed a simulation model of typical well in OLGA program, and several calculations was made for different values of the flow rate. Moreover, deep sand samples were isolated from a well of Uchebny field to compare the real data with the estimated one. Calculations are used to estimate the quality of mechanical impurity removal for various diameters, and a relationship between the critical diameter and well flow rate is built.

Проведены эксперименты по плавлению образцов флюоритсодержащих онгонитов из массива Ары-Булак при 700–800 °С, давлении 100 МПа и фугитивности кислорода, соответствующей буферам Ni–NiO и Mt–Hem. Во всех опытах достигнут предел содержания фтора в алюмосиликатном расплаве и насыщение по флюориту и топазу. Изменение фугитивности кислорода качественно не влияет на фазовые отношения в изученных образцах, но приводит к небольшому увеличению растворимости топаза и уменьшению растворимости флюорита в силикатном расплаве. В составе силикатного расплава происходит соответствующее изменение значения коэффициента агпаитности Ка и содержания СаО.
