Abstract
З використанням нейонних ПАР при різному
диференціальному тиску одержано афрони. Розподіл
бульбашок за розміром проведено за допомогою оптичної
мікроскопії з використанням програми FIJI-ImageJ2. Показано,
що структура поверхнево-активних речовин впливає на
властивості акронів (густину і в’язкість), розподіл за розміром
і кількість бульбашок. Визначення фільтраційних втрат про-
ведено на основі стандартних специфікацій для бурових роз-
чинів Petrobras/Бразилія. Показано, що структура нейоно-
генних ПАР має значний вплив на властивості рідин. Для при-
готування систем застосовано полі(етиленоксид) з 7 части-
нами оксиду етилену, та полі(етиленоксид)-b-полі(пропілен-
оксид) з 6 частинами оксиду етилену і 3 – пропіленоксіду.
Aphrons were produced using nonionic surfactants by applying a differential pressure. Bubble size distribution was obtained from optical microscopy using FIJI-ImageJ2 program. The aim of this work was to correlate surfactants structures with aphrons properties (density and viscosity), size distribution and the number of bubbles. API fluid loss tests were based on standard proceedings specifications for water-based drilling fluids of Petrobras/Brazil. The structure of the nonionic surfactants showed a great influence on the fluid properties and the performance of the fluid contributing with a filtrate reduction up to 31% with the systems that were presented between 1088 and 1850 bubbles with diameters ranging from 33 to 104μm. These systems were produced by poly(ethylene oxide) with 7 ethylene oxide units, a poly(ethylene oxide)-b-poly(propylene oxide) with 6 ethylene oxide units and 3 propylene oxide units.
