XU Xuan, YANG Zheng-ming, LIU Xue-wei, et al. Study of flow field measurement technique and distribution regularity of ultra-low permeability large-scale outcrop model[J]. 2012, 33(11).DOI:
a method for measuring the flow field of large-scale outcrop model is established. On this basis
flow field distribution regularity is studied by the model making by ultra-low permeability sandstone outcrops. The research shows that: for the large-scale outcrop model with nonlinear seepage characteristic
the flow field characteristic of the well pattern element is that the injection fluid advances rapidly along the main stream line but impact area is small; and non-flowing area exists
where displacement efficiency is low. The changing laws of flow field at different multiples are analyzed. The influences of different factors on flow field and displacement efficiency are studied. The large-scale outcrop model can reflect the dynamic process of flow field and displacement efficiency
and can simulate the seepage law of the real reservoir better.
