| 摘 要： | 研究了异常高压形成机制和分布特点，并对其在油气藏形成和保存中的作用进行了分析，认为，异常高压是油气自烃源岩呈况相涌流形式排出的动力；异常高压板值点位置的不同控制着油气在纵向上的分配量，其越靠近上部，向下排出的油气量越大，反之亦然；异常高压不仅可以对游离相油气进行封闭，而且可以对水溶相油气进行封闭，还可以对扩散相天然气形成浓度封闭；异常高压可以阻止地下水活动、氧和细菌对油气藏的破坏作用。

| Abstract: | The formation mechanism and distribution of abnormal high pressure and its role in formation and preservation of oil(gas) reservoir were studied, it is suggested that abnormal high pressure is the power of oil(gas) expulsion from source rock in the form of pour nuid of ndxed phases, the location of abnormal high pressure lindt controlled the distribution amount of oil(gas) in venical direction, the closer to upper reservoir, the larger is the expulsion, and vice versa. Abnormal high pressure can act as a seal for free and water-solvable oil(gas) and also a concentraion seal for natural gas. Abnormal high pressure can prevent underground water, oxygen and bacteria from destroying oil(gas) reservoir. |
