Study of Wettability of Reservoirs of Oil Fields by the Method of X-ray Tomography Core

Abstract: A b s t r a c tThe experience of the study of wettability of oil reservoirs on the core material using the method of x-ray tomography. The process of hydrophobization of rocks significantly changes the geological and technological conditions of oil fields. Standard methods of evaluating the wettability of the reservoir do not give a fully reliable assessment of this important for the decision of technological problems of the parameter. Developed a method of evaluating the wettability of reservoirs, based on th… Show more

“…Computer reconstruction of rock samples using the produces 2D images was carried out using the Avizo Fire software package. The software Avizo Fire was also used to calculate the pore volume and porosity of the rock samples before and after acidizing following the methodology outlined in [34][35][36].…”

“…На этапе фильтрационных испытаний необходимо в реагенты предварительно вводить рентгеноконтрастные растворы, которые, за счет большей рентгеновской плотности, лучше визуализируются на томограммах. К настоящему времени имеется некоторый опыт таких экспериментов [18][19][20][21], результатом которых обычно является визуальная оценка входа реагентов в керн без представления количественных оценок заполнения емкостного пространства.…”

“…С этой целью на первом этапе проведены лабораторные испытания по введению рентгеноконтрастной метки в полимер. На основании имеющегося опыта использования меток для томографии кернов [18,19] На следующем этапе с соблюдением пластовых условий проводились фильтрационные испытания на установке для исследования керна УИК-5ВГ. На основе раствора иодида натрия с добавлением полиакриламида марки SNF AN132 в концентрации 5000 ppm были приготовлены два состава с вязкостью 9,9 мПа•с.…”

“…Moreover, the mercury injection in throats always increases, but the incremental mercury injection in pores only corresponds to a narrower pressure range ( fig.2a). This means that samples of Well B have fewer pores being controlled by throats [12][13][14][15][16]. However, the mercury injection characteristics of the well W samples were different with uptake being controlled by pore bodies during early mercury injection, then as pressure increased the total mercury injection was controlled by pore throats (fig.2b).…”
