The utility model relates to a dry evaluation system of solid three -phase hybrid simulation well of gas drilling gas -liquid. The indoor analogue means function singleness of current gas drilling that exists, the problem that the energy consumption is big, the error is big have mainly been solved among the prior art. Its characterized in that: simulation wellbore hole (6) are through top cap (7) hollow simulation drilling rods of fixed connection (5), vent line (8) is connected to top cap (7) one side, simulation drilling rod upper end is through air compressor machine pipeline connection air compressor (2), steel can (12) are sealed through pipeline connection in air compressor machine pipeline middle part, airtight steel can (11) is connected to simulation wellbore hole (6) bottom, airtight steel can (10) are adorned to the sub -unit connection in simulation wellbore hole (6), plastics pipelines (13) are connected in vent line (8) exit, and plastics pipeline end -to -end connection has the detritus collection box. This dry evaluation system of solid three -phase hybrid simulation well of gas drilling gas -liquid, the simulation function is more comprehensive, and the energy consumption is little, the error is little.
