针对稠油油藏开发过程的薄弱环节,提出了油藏热质传递过程的黑箱分析法和白箱分析法,建立了包含蒸汽相的稠油热采耦合黑箱模型和白箱模型,使得储层温度场模型得以完整化和系统化。应用CMG软件进行数值模拟,验证了所建数学模型的合理性,并得到了孔隙度对油藏温度的影响关系。最后,对油藏热流体的指进现象进行了机理分析,并总结了热流体指进现象的产生范围。
Focusing on the weak part of heavy oil recovery, Black box and White box analysis are proposed in the heat and mass transfer process in oil reservoir, then Black box and White box models are developed containing steam phase, which complete and systematize reservoir temperature models. Numerical simulation is carried out by CMG software, from which verified the reasonable of models above and obtained the porosity effect on reservoir temperature. Fingering flow mechanism of heat fluid in reservoir is analysed, and the temperature ranges for engendering this fingering phenomenon are summarized.
