摘要
在分析和讨论方解石、石膏及黄铁矿溶解度的基础上,建立混合、溶蚀模型,运用PHREEQC软件模拟计算上述3种矿物在盐酸作用下的溶蚀性,讨论PHREEQC软件在模拟计算酸化液配方中的应用效果,并将模拟计算结果应用于现场试验中。模拟结果对改善低渗透砂岩铀矿含矿层的渗透性起到了很好的指导作用。
Abstract. Based on analyzing the solubility of calcite, gypsum and pyrite, a model was established. The dissolution properties of three minerals under the action of hydrochloric acid and water were sim- ulated by using PHREEQC software. The application effects of PHREEQC in simulating acidified liq- uid formulation are discussed. The simulation results were applied to field test, and play an instruc- tion rule in improving permeability of ore-bearing layer of sandstone-type uranium deposit.
