次生孔隙度是由诸如长石和自生成因胶结物(最常见的是碳酸盐碎屑颗粒)沉积后的淋滤作用造成的。在油气储层中次生孔隙度常在总孔隙度中占显著比例。因此,次生孔隙的出现具有重要的经济意义。目前,一个悬而未决的问题是孔隙度能否在地下深处得到提高。如果 Secondary porosity is caused by leaching, such as feldspar and autocatalytic deposition of cement, most commonly carbonate fracturing particles. Secondary porosity often accounts for a significant proportion of total porosity in oil and gas reservoirs. Therefore, the emergence of secondary porosity has important economic significance. At present, one of the outstanding questions is whether the porosity can be improved deep underground. in case
