摘要
鄂尔多斯盆地北部塔巴庙地区二叠系砂岩储层是主要的工业天然气产层之一。通过对砂岩储层样品的多项实验分析成果进行研究分析后认为,储层岩石颗粒的粒度、分选和成分是控制储层物性的主要因素;自生高岭石和自生石英起到改善储层物性的作用,而自生绿泥石和碳酸盐矿物则对储层物性有伤害作用。
The teservoir rock Permian system is one of the main productive formation for the commercian natural gas at Tabamiao region in North Ordos Basin.After analyzing all the experimental data of the reservoir rocks,it is found that the granularity, sorting and compon;ent of the reservoir rocks are principal factors controlling the porosity and permeability, the authigenic kaolilite and quartz play a role of improving the porosity and permeability, and the authigenic chlorite and carbonate play a role of damaging the porosity and permeablilty.
