摘　　要：矿化度是水中各项离子的质量之和。在实际水样不易实时获得时,通常会采用配制模拟水的方式,进行如储层敏感性流动实验或水处理实验。选取何种化合物和所选化合物的质量如何确定是配制模拟水样的关键。技术人员往往依据化学背景知识,采用自编计算公式的方式确定配制模拟水所需的化合物的种类及质量,公式编辑过程复杂费时。提出一种模拟水溶液配制的量化计算方法,遵循电中性原理和质量守恒理论,明确了模拟水配制所需的常用化合物种类和所需质量的计算公式,与实际水样相比,模拟水中各项离子浓度和矿化度的相对误差绝对值小于5%,一定程度上可还原实际水样。Salinity is the sum of the masses of various ions in water.When the actual water sample is difficult to obtain in real time,it is usually used to prepare simulated water,such as reservoir sensitivity flow experiment or water treatment experiment.What kind of compound to choose and how to determine the quality of the selected compound are the key to prepare simulated water sample.According to the chemical background knowledge,technicians often use self-edited calculation formula to determine the type and quality of compounds required for the preparation of simulated water,which is complicated and time-consuming.A quantitative calculation method for the preparation of simulated solution is presented.It conforms to the theory of electrically neutral and mass conservation.The calculation formula of common compound types and mass required for simulating water preparation was clarified.Compared with the actual water sample,the absolute relative error of ion concentration and salinity in simulated water is less than 5%,which can reduce the actual water sample to a certain extent.
