The reservoir of middle porosity and low permeability with solution pore and remainder intergranular porosity is distributed of the point-sandbar deposit and the distributor channel deposit are mainly objective formations of exploration in South Yi-Meng;
其中中孔低渗型储层以溶蚀孔和残余粒间扎为主,多发育于南部三角洲平原分流河道砂体及北部的曲流点坝中,为伊盟地区的主要储集层;
original porosity is typified by the intergranular porosity of sandstones and the intercrystalline and oolitic porosity of some limestones
原生孔隙度以砂岩粒问孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。
The type of pore is mainly vuggy porosity, and primary intergranular pores, relatively undeveloped, is as the second place among the reservoir pores.
孔隙类型主要为各种溶蚀孔,其次为原生粒间孔。
Although automorphic or partial automorphic quartz cementation losses some intergranular pores in late diagenesis, the reservoir with relatively high porosity still can be formed.
虽然晚成岩期自形或半自形石英胶结损失了部分粒间孔隙,但仍能形成孔隙度相对较高的储层。
