Abstract:

This paper studies the solution of dimensionless bottom ressure in LaplacOspace about variable rate under two inner oundary conditions. On the base of the structure and relation of the solutions analysis , the relation of bottompressure is found out in common composite reservoir , dual porous reservoir and homogeneous reservoir , and corresponding application of the solution is simply introduced. The research makes well test theory perfect , and makes well test software have more application value.

Key words: Dual Porous Composite Reservoir, the bottom
