The Research on the Size and the Ascending Velocity of Oil Drops Spilling from Tiny Holes of Seabed Pipelines;

8% when the average size of oil drop ranges from 21.

The error of charge contained in an oil drop is obtained by means of error transmission method, also the degree of effect on every physical quantity measured directly to the error is analyzed.

A new method of data processing in Milligan oil drops experiment;

The current situation of oil-water sludge,the movement rule of and the forces on the solid impurity particles,oil drops and water of the oil-water sludge in centrifugal force field were introduced,and relevant physical models were established.

This paper mares some analysis that two factors of oil drop volatilitation in uniform down will influence the experiment of oil drops,and raises some points to be noticed in experiments.

Study of coalescence behav-ior of oil droplets iu chemical flooding system;

This paper deals with the computer aid modulate calculation of diesel oil droplet evaporation, and the law of changes in temperatures, diameters and qualities of droplets under different conditions.

Considering collision coalescence of dispersed oil droplets in oil field wastewater,the dynamic information of all oil droplets within the inclined plate oil remover were obtained by simulation,which can be used in the calculation of the oil removal efficiency of inclined plate oil remover.
