摘　　要：葡48X区块油层为特低渗透储层、致密油开采,纵向较分散,平面连续性差,具有油质密度高、含水低的特点,开发动态监测难。采用微波持水率计产出剖面测井仪进行分层流量测试,利用微波在油、水中传播速度,以及衰减差异性计算介质含水率,得到分层油水产量。应用微波持水率计对葡扶1X井进行多点测试,现场试验分析确定1565.4 m测点处为主产层。对该井进行超声多普勒测井,对比井温数据结果表明,微波持水率计产出剖面测井结果更准确。该方法可对葡48X区块致密油开采进行有效动态监测,提高低含水率致密油分层产出测试精度,为油田精细开发提供新的技术手段。Pu48x block oil layer is a tight oil reservoir with ultra-low permeability,and its vertical dispersion is scattered and plane continuity is poor.It has the characteristics of high oil density and low water cut,which makes it difficult to monitor the development performance.The microwave water holdup meter and production profile logging tool are used for layered flow test.The principle is to calculate the water content of the medium by using the propagation velocity of microwave in oil and water and the attenuation difference to obtain the layered oil-water production.The microwave water holdup meter is used to conduct multi-point test in Well Pufu1X.Through field test analysis,the measured point-1565.4 m is determined as the main production layer.Compared with the well temperature data,the profile logging result of the microwave water holdup meter is more accurate than ultrasonic Doppler logging method.This method can effectively monitor the tight oil production in Pu48x block,improve the layered production test accuracy of tight oil with low water cut,and provide a new technical means for fine development of the oilfield.
