原地浸出中井孔的抽注水能力是决定铀矿岩地浸的主要条件,当下我国许多的研究对某低渗透砂岩铀矿岩心的特定都进行了相应的参考研究,对于其与地层之间的渗透能力进行了相应的分析探究。分析结果表明,砂岩是由石英、钾长石和钠长石为基本骨架所构成的;其内部的黏土主要包括蒙脱石和绿泥石,并且含量相对较高;在孔隙中固定的体积所占比例较大,孔喉的直径偏小,导致整个渗透能力较弱,这些特点都导致矿层可能在一定程度上会受到流体的影响而产生损耗。
The ability of pumping water from in-situ leaching out of the middle hole is the main condition that determines the leaching of uranium ore. Nowadays, many researches in our country have made corresponding reference research on the specific core of a low-permeability sandstone uranium deposit. The ability to conduct a corresponding analysis. The results show that the sandstone is composed of quartz, potassium feldspar and albite as the basic skeleton. The clay in the inner part of the sandstone mainly consists of montmorillonite and chlorite, and the content is relatively high. The proportion of the fixed volume in the pore Larger pore throats are smaller in diameter, resulting in weaker overall permeability, all of which can cause the seam to be affected to some extent by the fluid and cause losses.
