摘　　要：微运移机制是目前油气化探等非地震直接找油的理论基础,只有研究清楚油气微运移的相态,才可能进一步研究微运移的机制;含油气水相是油气发生微运移最普遍和优先起作用的相态;在特定的地质条件下,不排除油气以其它相态发生渗漏的可能。Micro-migration mechanism is currently the theoret-ical basis of non -seismic direct petroleum prospecting such as geochemical exploration.A thorough understand-ing of hydrocarbon phase state of petroleum micro-migra-tion is the precondition of further study of micro-migra-tion mechanism.Water phase containing oil and/or gas is the most common and preferentially functioning phase that leads to micro-migration of hydrocarbon.Hydrocarbon seepage also can occur in other phases under specific geologic conditions.
