委内瑞拉MPE-3区块超重油冷采过程中泡沫油开采机理
摘要
Abstract
Super heavy oil is characterized by high asphaltene content and oil gravity. The recovery mechanism of solution gas drive with horizontal wells for super heavy oil has been studied, including the mechanism of forming foamy oil, unconventional PVT behavior and oil displacement feature. The experiment results show that when reservoir pressure is lower than bubble point pressure, a great amount of tiny bubbles will form in crude oil and will retain in oil phase for a long time, resulting in many different features from conventional solution gas drive. Foamy oil behavior is related to reservoir depletion rate, pressure drop level as well as confining pressure. Horizontal well cold production can obtain higher oil production and recovery factor.关键词
