Optimization of perforation project for inhibiting water coning by water recovery with single tube in the bottom water drive reservoir;

Similarity theory of recovery percent and water cut in water flooding reservoir;

On the basis of obtaining solution of mathematical model,and taking into account the influence of wellbore storage and skin effect and the strength of water-drive,the paper calculated typical curves of pressure and pressure derivative for oil well in water-drive oil reservoir,analyzed the characteristic of pressure behavior,these works provided theory basis for well test.
