中文摘要：
从流体热膨胀性、黏度、润湿性等多个方面开展超低渗透稀油油藏热水驱研究。超低渗透稀油油藏较特低渗透油藏储层岩石更加致密,孔隙度更小,渗透率更低且渗流阻力更大,储层流体在地层中流动表现为非达西流动,并表现为更强非均质性。
英文摘要：
From the factors of the injected fluid thermal expansion effect, viscosity, wettability, this paper carries out hot water flooding study.The ultra-low reservoir owns more compacted rock and smaller porosity as well as lower permeability and the seepage resistanse, and the fluid flow in the reservoir is non-Darcy flow. The ultra-low reservoir reflects the more heterogeneity.
