ИССЛЕДОВАНИЕ ОСНОВНЫХ ПАРАМЕТРОВ ПОЛИМЕРНОЙ ТЕХНОЛОГИЧЕСКОЙ ЖИДКОСТИ И ЕЕ ВЛИЯНИЕ НА КОЛЛЕКТОРСКИЕ ХАРАКТЕРИСТИКИ ПОЛИМИКТОВЫХ ПЕСЧАННИКОВ

Abstract

Сохранение коллекторских свойств флюидов вмещающих резервуаров при их вовлечении в разработку является важной на сегодняшний день задачей. Это связано с уменьшением ресурсной базы углеводородов, относительно легких для извлечения и усиленным вовлечением в разработку пластов, отличающихся сложным литологическим составом горных пород, низкими фильтрационными и емкостными свойствами, большими глубинами залегания, а также жесткими термобарическими условиями (высокие температуры и давления в продуктивном пласте). Таким образом, перед тем, как использовать ту или иную технологическую жидкость для какого-либо мероприятия, необходимо проводить ее исследования в специализированных лабораториях, для исключения или минимизации риска неудачного геолого-технического мероприятия. В представленной статье изучены основные свойства полимерной технологической жидкости на основе ксантана, используемой при первичном вскрытии, перфорационных работах, глушении и т.д. Проведен фильтрационный эксперимент по моделированию первичного вскрытия на образце полимиктового песчаника, отобранного на Вынгапуровском нефтегазоконденсатном месторождении, расположенном в Западной Сибири, с помощью установки, позволяющей проводить оценку степени повреждения продуктивных горизонтов FDES-645 (CoretestSystems). Оценена величина изменения фильтрационных характеристик образца керна после воздействия на него полимерной технологической жидкостью, при моделировании процесса первичного вскрытия продуктивного пласта.

Keeping the reservoir properties of the reservoir fluids during their involvement in the development is an important task for today. This is due to a decrease in hydrocarbon resource base, relatively easy to extract and increased involvement in the development of layers with different complex lithological composition of formations, low filtration and capacitive properties, greater depths of occurrence, as well as hard thermobaric conditions (high temperature and pressure in the reservoir). Thus, before you use a particular process fluid for any event, it is necessary to carry out its investigation in specialized laboratories, to eliminate or minimize the risk of failure of geological and technical measures. In the present study the basic properties of the paper processing liquid polymer based on xanthan used in the primary opening, perforating, jam etc. An experiment on modeling the filtration primary opening the sample polymictic sandstone, selected in the Vyngapurovskoye oil and gas condensate field located in Western Siberia, by setting to allow evaluation of the degree of damage to the productive horizons FDES-645 (CoretestSystems). Estimated amount of change in the filtration characteristics of the core sample after exposure to polymer process fluid in the simulation process, the primary completion fluids.
