The percolation mechanism of low permeability reservoirs differs a lot from that of conventional gas reservoirs. 由于低渗气藏一般具有低孔低渗的特点,所以其渗流机理与普通气藏相差很大。
Dissolition is favorable for secondary porosity, thus forming available reservoirs in some sections of low porous and low permeable clastic rocks. 从而使某些砂岩段在低孔低渗储层中形成较发育的次生溶蚀孔隙和成岩微裂缝,并成为有效孔隙。
