| 摘 要： | 原油中通常含有大量重组分，在一定的温度和压力下它们将以固体形式沉淀下来，引起堵塞管道及许多油藏开发问题，论文提供了一个预测液固相平衡的热力学模型。应用该模型可以进行闪蒸计算和边界计算，确定固体组分沉淀的临界温度和临界压力，从而在开发中有取相应措施，它对于指导油气田开发有重要的理论意义和实际意义。

| Abstract: | Crude oils usually contain a lot of heavy hydrocarbons which may precipitate as solid phase at certain temperatures and pressures,leading to the plugging of oil and gas transmission pipelines and numerous other field problems.This paper presents a thermodynamic model for predicting the liquid-solid phase equilibrium.This model can be used to perform flash calculations and boundary calculations to determine the onset temperature (or pressure)of solids crystallization.We can take measures to deal with this situation in development.It has important meaning in theory and practice for reservoir development. |

| Keywords: | crude oil solids deposition thermodynamic model liquid-solid phase equilibrium onset temperature onset pressure prediction |
