摘要
大斜度井中多相流持率计算一直是困绕人们的技术难题,流态及流型判定是影响持率计算的主控因素。常规测井仪器大多为居中测量,很难准确地测量评价整个井筒流动情况。综合分析不同流量及测量方式对持率的影响,结合测量特点,选用电容阵列多相持率测井仪CAT(Capacitance Array Tool),建立适用的解释模型,从不同流量、角度进行实验研究,确定大斜度井中多相流持率计算方法。根据实验测井资料分析解释,建立了适用于大斜度井中持率计算方法,提高了持率计算的准确度。
In high angle wells, calculating holdup of multiple phase flow is always a difficult tech- nique problem, the judgment of flow regime and flow pattern is the main effect on calculating the holdup. Conventional logging tools are mostly centralized measurements, so it is very hard to ac- curately measure and evaluate the flow condition in the whole wellbore. Analyzed are the effects of different flows and measuring methods on the holdup. According to the measuring features, the CAT（ Capacitance Array Tool） is used to establish an applicable interpretation model. Determined are the calculation methods of holdup of multiphase flow in high angle wells based on the experiments of different flows in different borehole inclinations. Explanation of the experimental logging data shows the holdup calculation methods are suitable for the high angle wells and increase the accuracy of calculation of holdup.
