Аннотация В статье рассматривается проблематика, связанная с изучением процессов, которые протекают при насыщении ожелезненных образцов горных пород моделью пластовой воды на основе хлорида натрия, а также влияние изменения давления на стабильность структуры образца и ее состава. Сотрудниками ПАО «НК «Роснефть» совместно с работниками лабораторного комплекса ООО «НК «Роснефть-НТЦ» (дочернее общество ПАО «НК «Роснефть») проводится сравнительная характеристика данных открытой пористости, полученных методом насыщения водой и газом. Практическая применимость данного исследования заключается в необходимости учитывать фактор растворения минералов, содержащих железо, при насыщении под давлением. Материалы и методы Лабораторные исследования методом оценки петрофизических свойств с определением коэффициента пористости по газу и по жидкости на пермеаметр-порозиметре.

Abstract The article describes the problems associated with the study of the processes that occur in saturated iron-contained rock samples by a model of formation water based on a sodium chloride. The effect of pressure changes on sample structure stability and its composition are also discovered. The employees of “Rosneft” PJSC together with employees of the laboratory complex “Rosneft-STC” LLC (a subsidiary of “Rosneft” PJSC) conduct a comparative characteristic of open porosity data obtained by the method of saturation with water and gas is carried out. The practical applicability of this study is to take into account the dissolution factor of minerals containing iron upon saturation under pressure. Materials and methods Laboratory research method for evaluating petrophysical properties with determination of the porosity coefficient for gas and liquid on a permeameter-porosimeter.

Keywords rock, saturation, open porosity coefficient, pressure, formation water, pyrite, siderite
