| Abstract: | The maximum pump pressure is the important parameter in foaming drilling. Through introducing the system parameter R0,the paper gives a simplifed and clear formulae describing pressure, proving the basis fer operation on the spot and computerization. Comparing with old calculation method such as Rhenold method,R0 is a new calculation method. |

| Keywords: | System parameter R0 volume ratio a of gas to liquid circular pressure inner pressure inside pipe |
