There are numerous methods for definition of bottom pressure in different group of wells. Bottom pressure is the basic parameter for hydrodynamic estimations. Purpose of the article is to develop methods for bottom pressure counting in working oil, gas condensate and gas wells. As a result of carried out studies are given equations gas condensate mixture moving along the vertical pipe. Via some simplifications moving equation has been integrated and obtained equation for definition of bottom pressure for oil, gas condensate and gas wells. In obtained equations were applied field parameters and results were compared with measured data. Taking into consideration some insignificant errors, the method may be applied in large practice. Equation specify bottom pressure for wells of gazocondensat and gas have been received. As received equation is pressure of bottom where have counted with mine parameters and measured. As mistake is little to apply methods given in the practice widely is possible.
