烃混合物物理性质的估算是油田工作各个阶段设计的重要步骤。流体性质的变化与压力和温度有关,应该从油藏工程和开发设计工作的两方面考虑。例如,计算管状系统中出现的两相流动压力梯度,需要予计的流体性质。如溶解气、地层条件下的体积因子(FVF)、原油的压缩系数和井内各个位置下的粘度。虽然这些性质是通过试验测量的,但它也是压力的函数,通常这种测量仅和储层温度有关,这些性质的动态与温度的变化有关。往往,这些是靠经验予测的。
Estimation of the physical properties of hydrocarbon mixtures is an important step in the design of each stage of the field work. Fluid properties change with pressure and temperature, should be considered from two aspects of reservoir engineering and development and design work. For example, calculating the two-phase flow pressure gradient that occurs in a tubular system requires the expected fluid properties. Such as dissolved gas, volumetric factor in formation (FVF), compressibility of crude oil, and viscosity at various locations in the well. Although these properties are measured experimentally, it is also a function of pressure, which is usually only related to reservoir temperature. The dynamics of these properties are related to changes in temperature. Often, these are measured empirically.
