摘要：

勘探实践和物理模拟实验都表明深盆气藏内存在不同成因特征的含水层,鄂尔多斯盆地苏里格盒8段深盆气藏主要存在两种不同成因类型的水层-具有气水同层的常规透镜体砂岩气藏的底水和位于深盆气藏的气水过渡带局部高孔渗砂岩体"岩性"气藏的底水;实验表明,除了在深盆气形成的鼎盛时期深盆气藏内不含水之外,深盆气形成演化的各个时期都是含有水的,这些水可以是深盆气形成前的孔隙水(在深盆气形成的建设时期),也可以是深盆气萎缩时期地层水进入局部高孔渗砂体形成的"岩性"气藏中的底水。位于深盆气运移路径上的局部高孔渗砂体不含或少含水而富含气,是进行深盆气勘探的有利目标。

Abstract:

Both exploration proactice and physical modelling indicate that deep basin gas accumulations contain aquifers of various geneses.Aquifers in deep basin gas pool of He-8(the eighth member of Shihezi Formation)in Sulige region,Ordos basin, are of two origins—one is bottom water in common lenticular sandstone gas reservoirs with mixed water and gas layer,and the other is bottom water in "lithologic" gas reservoir within the local sandbody of high-porosity and high-permeability in gas-water transition zone of deep basin gas pools.Experiments indicate that water present almost in all but the high tide stages of the evolution of deep basin gas pools.It could be pore space water existed before the accumulation of deep basin gases or bottom water in lithological gas reservoirs formed during the senescence phase of deep basin gas when formation water entered the high-porosity and high-permeability sandstones.It is suggested that the high-porosity and high-permeability sandstones on the migration paths of deep basin gases contains no or very limited amount of water and serve as the most favorable exploration targets for deep basin gas.

Key words: deep basin gas, genesis of aquifer, simulation experiment, Ordos basin
