The experiment result showed that the plugging took place in the oil-sand interface, and the o.

Molecular dynamics simulations on the aggregation of AOT at oil/water interface;

In this paper research on the oil/water interfacial shear viscosity is reviewed and prospects for the study of oil/water interfaces are also put forward.

Analysis of dominant factors of the oil-water interface in the oil reservoir of Sanjianfang Formation,Shanshan Oilfield;

Adsorption behavior of surfactant in oil-water interface;

Study of the method to extract oil-water interface automatically from MDT data;

Mass transfer kinetics of PVP across oil-water interface by using micro visualization technique;

By analysis of gradient curves about formation pressure,improved method is advanced which can automatically pick up oil-water interface of oil reservoir from gradient curves about formation pressure by the third power of inserting value function and maximum value principle.

Adsorption properties of soy glycinin adsorbed at the air-water and oil-water interfaces were studied by dynamic drop shape analysis.

Determining both oil-water contact and thin interbed by analysing the resistivity log data of horizontal borehole;

In recent years, it can be found that there is an obvious difference between the present oil-water contact and the past one by the drilling of new infilling wells in Sanjianfang reservoir; and in the whole, the oil-water contact takes on a new situation that is high in the north and low in the south, high in the west and low in the east.

The result shows that the oil-water contact is controlled by the structure,fault,sand distribution,petrophysical property and diagenetic epigenesist and is an irregular dip plane;reserves distribution is well related to the distribution of braided channel micro-facies in the.
