摘　　要：基于非线性测量的电磁流动成像测井,几乎不受井斜角度的影响,对水平井的流动剖面测量提供全新的方法。研究利用电磁流动成像测井进行持水率计算和气水分层界面位置识别的方法。根据电磁流动成像测井方法原理设计制作阵列式电磁流动成像测井实验仪;研制实验装置,制定实验方案,进行气水两相水平流动模拟电磁成像测井实验;整理分析实验数据,计算持水率和气水分层界面位置。根据模拟流动实验数据计算持水率与实际持水率之间的相对误差小于2%,计算气水分层界面位置与实际层界面位置的相对误差小于3%。The electromagnetic flow imaging logging, based on nonlinear measure, is almost not affected by the inclination angle, and provides a new method for the flow profile measurement of the horizontal wells. With the electromagnetic flow imaging logging, a method for water holdup calculation and interface between gas and water identification is studied. Firstly, the array electromagnetic imaging logging experiment device is designed and manufactured according to the principle of electromagnetic flow imaging logging. With developing the experimental devices and scheme, gas-water two-phase horizontal flow simulation experimentation is completed. Finally, the water holdup and gas-water interface are calculated with the experimental data measured by the device. The results show that the relative error between the calculated and the measured water holdup is less than 2% and the relative error between the calculated and the measured interface location is less than 3%.
