摘要

位于向斜底部或斜坡上的气藏,被称作深盆气藏,有研究认为深盆气藏的显著特征是气水倒置。而实际上,深盆气藏并不是一个科学概念,气水倒置也不会发生。根据研究,大尺度容器中气水不会倒置,重力分异会使气水呈正常分布。均匀毛细管中也不会出现气水倒置,浮力作用会使气体向上运移。上粗下细型毛细管中,气体向上运移的动力更加充足,也不可能出现气水倒置。上细下粗型毛细管因为毛管压力的封堵作用,阻止油气向上运移,使油气聚集起来。常规构造气藏盖层和岩性油气藏围岩中也都有地层水,但都不是气水倒置。砂岩地层因非均质性而出现物性圈闭或物性油气藏,物性圈闭不一定出现在构造的顶部,而可以出现在地层的任意位置。文中提出的物性圈闭是一个科学概念,它可以替代深盆气藏圈闭,更好地指导油气勘探。

Abstract

Deep gas reservoirs usually situate at the bottomor the side slope of a syncline. The main feature of deep gas reservoirs is the inversion of gas and water distribution. Actually the deep gas reservoir is not a scientific concept, and the inversion of gas and water can not happen at all. According to the study, the gas and water in a huge container can not be inverted, and gravity separation can make gas and water distribute normally. The gas and water in a uniform capillary can not be inverted, and buoyancy can move the gas upward. The gas and water in a funnel-shape capillary can also not be inverted because there is a stronger driving force tomove gas upward. The inverse funnel-shape capillary can stop the further move of gas upward with the sealing of capillary pressure and make the gas accumulate. In the caprock of conventional structural gas reservoirs and in the surrounding rocks of lithologic reservoirs, there is formation water, but it is not inverted with the gas in the reservoirs. Due to heterogeneity, the traps of physical property form in sandstone formations and the traps of physical property can be anywhere of a formation, but it may not necessarily stay on the top of a structure. The trap of physical property proposed is a scientific concept, and it can replace the deep gas trap and serve the oil and gas exploration better.
