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。
Aimed at the weak links in the development of heavy oil reservoirs, a black box analysis and a white box analysis of the heat and mass transfer process are put forward. A coupled black box model and a white box model are established for the thermal recovery of heavy oil reservoirs, The temperature field model is completely and systematized. The numerical simulation with CMG software verifies the rationality of the mathematical model and obtains the effect of porosity on the reservoir temperature. Finally, the mechanism of fingering of thermal fluid in reservoirs is analyzed, and the range of fingering of thermal fluid is summarized.
