储层中的粘土矿物对化学驱提高原油采收率至关重要,其中粘土矿物与碱化学剂作用的影响尤为突出,为搞清储层中常见的粘土矿物与化学驱中常见的几种碱剂的相互作用机理,变化规律,以及由此产生的矿物碱耗大小,影响因素和相互关系,探索和建立较为完善的碱耗预测模型,建立了一套粘土矿物碱耗的定量预测的研究方法。运用此套方法不仅能预测动态砂管的碱耗规律,而且为预测实际地层中碱剂传质规律有重要的科学价值。
Clay minerals in reservoirs are crucial for chemical flooding to enhance oil recovery. Among them, the effect of clay minerals and alkali chemicals is particularly prominent. In order to understand the common clay minerals and chemical flooding in reservoirs, Agent interaction mechanism, the change rule, and the resulting mineral alkali consumption size, influence factors and interrelationships, to explore and establish a more perfect prediction model of alkali consumption, set up a set of quantitative prediction of clay mineral alkali consumption research methods . The method can not only predict the law of alkali consumption of dynamic sand tube, but also have important scientific value for predicting the mass transfer law of alkali agent in the actual formation.
