New Pressure Drop Calculation Model of Gas-water Two-phase Conduit Flow for the Horizontal Well

CHEN Jun1 WANG Chuan-jie1 YANG Hao-long1 XU Guang-peng2(1.Southwest Petroleum University,Chengdu 610500;2.Western Sichuan Gas Recovery Plant,Southwest Oil and Gas Company,Sinopec Group,Deyang 61800)  
In order to know pressure drop correctly,the paper proposes a new pressure drop calculation model of gas-water two-phase conduit flow for the horizontal well based on two assumptions: one is speed of gas phase equal with water phase;the other is two-phase media reaches thermodynamic equilibrium,and pressure,density,etc,are mutual single value function.The calculation results show that horizontal wellbore pressure monotonic decreases along root direction of toe-end,and pressure drop around toe-end is smaller than that of other place in the wellbore obviously.
