Method for remodeling argillaceous weakly cemented sandstone
The invention discloses a method for remodeling argillaceous weakly cemented sandstone. The method is suitable for researching geological samples in special areas. The method comprises the steps of: firstly, performing mother rock mechanical crushing, and achieving separation of main sandstone particles and interstitial substances through washing and filtering; and then carrying out warm-pressingsolidification to promote inlaying occlusion among the sandstone particles so as to form cementitious-substance-free cementation and iron cementation effects, further carrying out pressure-maintainingrewarming, realizing argillaceous cementation in sandstone through slurry-like interstitial substance permeation, and finally realizing calcareous cementation among the sandstone particles through carbon dioxide injection. No cement, iron, argillaceous and calcareous cement exists in indoor remolded argillaceous sandstone, and meanwhile the main substance components of the remolded sandstone arekept the same as those of parent rock. The method is simple in step and good in using effect, and the properties of clay minerals in sandstone are not changed.
本发明公开了一种含泥质弱胶结砂岩重塑方法，适用于研究特殊区域地质样本。首先进行母岩机械破碎，通过洗滤实现砂岩主要颗粒与填隙物的分离；然后进行温压固化促进砂岩颗粒间的镶嵌咬合，从而形成无胶结物胶结和铁质胶结作用，进而进行保压复温，并通过浆状填隙物渗透实现砂岩中泥质胶结，最后通过二氧化碳注入实现砂岩中颗粒间的钙质胶结作用，在室内重塑含泥质砂岩中无胶结物、铁质、泥质、钙质胶结，同时保持重塑砂岩主要物质成分与母岩相同。其步骤简单、使用效果好，且不改变砂岩中粘土矿物性质。
