Considering gas-solid flow in annular space and BoYun Guo's hydrodynamic parameters model, For aired underbalanced drilling, combined with the minimum energy Angel law and based on the mininum gas injection scale at the key points, it is established a bottom-hole pressure model for gas-solid two phase stream; meanwhile, calculated the downhole depth of the Downhole-Deployment-Valves; and then fabricated the corresponding calculation software. For streamingly underbalanced drilling, it is fully given a step-by-step solution based on analysis from the relationship of various wellbore pressures at the course of underbalanced drilling as well as from the streaming behavior in different wellbore sections, adding consideration on multiphase stream pressure drop and Downhole-Deployment- Valve into account, it is of common application for development wells.
