水平井油水两相流型实验研究

Experimental Study on Oil-water Two-phase Flow Pattern in Horizontal Well

为了研究水平井油水两相在不同流量和不同含水率条件下的流型流态,采用多探头系列仪器组合常规涡轮,在多相流模拟实验室进行水平井油水两相模拟实验。通过实验研究,油水两相在水平井中的流型类别可分为分层流、油包水-水、水包油-水、油包水和水包油五种,建立了流型图,可为水平井生产测井施工设计和状态分析提供流型参数。

In order to study the flow patterns of oil-water two-phase horizontal wells at different flow rates and different water cuts,the study uses multi-probe series instruments combined with conventional turbines to conduct horizontal well oil-water two-phase simulation experiments in the multiphase flow simulation laboratory. Through experimental research,the flow pattern of oil-water two-phase in horizontal wells can be divided into five types: stratified flow,water-in-oil-water,oil-in-water-water,water-in-oil,and oil-in-water;and a flow pattern diagram has been established,Can provide relevant flow pattern parameters for horizontal well production logging construction design and status analysis.
