相态特性模型的状态方程可用来描述含水高温高压流体特性。水(极性)与烃(非极性)间的相互作用可以通过将不对称(非随机)项添加到具有常规(随机)混合定律的吸附项上来进行模拟。多种烃类中气-液和液-液烃水溶解度参数被用来确定常规和非随机项间的双元反应参数。已开发的相态特性模型是在一较宽温度范围内利用烃和水的两元及三元混合物的两相和三相平衡参数进行评价的,而不是应用开发此模型的数据。水对高温高压下的纯烃和两元混合烃的影响也正在进一步的研究中。配有毛管黏度计的高温高压装置测量的温度范围是150~200℃,压力高达20000lb/in2(A),其测得的数据用来评价残余黏度模型。
The state equation of the phase behavior model can be used to describe the characteristics of a hydrous, high temperature and high pressure fluid. Interactions between water (polar) and hydrocarbons (non-polar) can be modeled by adding an asymmetric (non-random) term to the sorption term with the usual (random) mixing law. The gas-liquid and liquid-liquid hydrocarbon water solubility parameters of a variety of hydrocarbons are used to determine the binary reaction parameters between regular and non-random terms. The developed phase behavior model was evaluated using the two-phase and three-phase equilibrium parameters for both binary and ternary mixtures of hydrocarbons and water over a wide temperature range, rather than applying the data developed for this model. The effect of water on pure hydrocarbons and binary mixed hydrocarbons under high temperature and pressure is also under further study. High temperature and pressure devices equipped with capillary viscometer measure the temperature range is 150 ~ 200 ℃, the pressure up to 20000lb / in2 (A), the measured data used to evaluate the residual viscosity model.
