Capillary pressure curves are needed to describe the process of waterflooding in complex, heterogeneous formations, are used as well to determine the residual water saturation and the distribution of pore size. It should be noted that capillary forces affect the promotion of the front of the institution and consequently on the ultimate oil recovery.</p></abstract><trans-abstract xml:lang="ru"><p>Капиллярные силы вместе с гравитационными силами контролируют первоначальное распределение флюидов в пласте-коллекторе по вертикали, поэтому данные о кривых капиллярного давления могут использоваться для прогноза неподвижной и подвижной воды в гидрофобной системе по вертикали. Кривые капиллярного давления нужны для описания процесса заводнения в сложных, неоднородных пластах, применяются также для определения остаточной водонасыщенности и распределения пор по размерам. Стоит отметить, что капиллярные силы влияют на продвижение фронта заведения и, соответственно, на конечную нефтеотдачу пласта.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кривые капиллярного давления</kwd><kwd>поверхностное натяжение</kwd><kwd>радиус поровых каналов</kwd><kwd>относительные фазовые проницаемости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>curves of capillary pressure</kwd><kwd>surface tension</kwd><kwd>radius of the pore</kwd><kwd>relative permeability</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Актуальные проблемы нефтегазового дела: сб. науч. тр. / редкол.: Мухаметшин В.Ш. и др.: в 4 т. – Уфа: Изд-во УГНТУ, 2006. – Т.1. – 181 с.</mixed-citation><mixed-citation xml:lang="en">Aktual'nye problemy neftegazovogo dela: sb. nauch. tr.
