摘　　要：泡沫钻井在欠平衡钻井工艺中占有重要地位,能解决低压、低渗、易漏地层的钻井难题。研制了泡沫钻井与井筒多相流动试验装置,该装置由井筒模拟系统、起升装置、供液系统、供气系统、采集系统等组成。模拟井筒采用透明有机玻璃材料,实现了试验过程可视化。对装置流体进行实时压力、流量检测,进行泡沫钻井试验定性和定量分析。试验表明,该装置能清晰观察泡沫携带钻屑及钻铤处流体对井壁的冲蚀过程,实时检测钻井液的黏度、流速、密度、剪切力等参数,定量分析钻井液对钻进过程的影响特性。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 developed.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 wellbore,and visualization was achieved.The pressure and flow discharge of the fluid in units was monitored 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 wellbore in drill collar,and the parameters of the drilling fluid had been monitored in line,such as viscosity,flow rate,density,shearing force,etc.and could analysis the performance of drilling fluid influencing on drilling quantitatively.
