One is an existing inconsistency between the hypothesis and the potential applied in vertical radial flows, the other is a conditional formula in anisotropism formation.

Application in the submarine vertical plane motion control unit design of Kalman filtering

For acquiring present formation pressure of gas well in time and providing a basis for geologic study and interpretation, dynamic analysis and reservoir potential calculation, a facility method to calculate formation pressure of gas well is presented on base of systemic well test principle of gas well and vertical pipe flowing theory.
