О механизме гидрофобизации поверхности пород-коллекторов нефти и газа

О механизме гидрофобизации поверхности пород-коллекторов нефти и газа

Abstract

На представительном статистическом материале проведен анализ влияния на смачиваемость продуктивных пород различных факторов физико-химической природы. Для объяснения экспериментальных фактов использована коагуляци-онная теория ДЛФО, базирующаяся на расклинивающем давлении, возникающем в тонкой прослойке воды, которая экранирует активные компоненты нефти от поверхности минералов. Устойчивость пленки зависит от минерализации воды, водородного показателя и специфической активности положительных и отрицательных ионов.

An influence of various factors of physical and chemical nature on the wettability of productive rock was analyzed based on a representative statistical data. Coagulation DLVO theory, based on the disjoining pressure arising in the thin layer of water, which shields the active components of the oil from the surface of minerals, was used to explain the experimental results. Stability of the film is dependent on water salinity, pH value, and the specific activity of positive and negative ions.
