It is important for foam drilling to drill in drilling technology,and it can solve problems such as drilling in low-pressure,low permeability,leaky layer,and it must be researched deeply. Therefore,an experimental unit about foam drilling and multiphase flowing in well was devel-oped.It is made up of simulation wellbore system,hoisting units,liquid system,gas system,data acquisition system,etc.The transparent Polymethyl methacrylate was used in simulation well-bore,and visualization was achieved.The pressure and flow discharge of the fluid in units was mo-nitored in line,and the qualitative and quantitative analysis was achieved.Tests showed that it was clearly to see the course of the foam drilling fluid carrying cuttings and the fluid eroding well-bore in drill collar,and the parameters of the drilling fluid had been monitored in line,such as vis-cosity,flow rate,density,shearing force,etc.and could analysis the performance of drilling fluid influencing on drilling quantitatively.
