摘　　要：利用声幅测井评价方法,室内设计了一种模拟测井评价仪器。该装置能够360°旋转,可以判别不同方向、不同位置上的水泥胶结情况。制作水泥胶结模型,设计不同胶结情况,对仪器进行了测试,能够准确判断第一、二界面胶结质量。在界面间隙位置分别充填油、气、水介质进行声幅测试,建立了油、气、水介质的声幅曲线图版。研究结果表明,声幅幅度与界面间隙有较好的相关性,该方法能够鉴别环空间隙存在位置以及间隙中所含油、气、水介质情况,对现场测井解释具有一定的指导意义。By using sonic amplitude logging evaluation method,an analog logging evaluation device is designed in laboratory .The device can rotate 360°,and can judge cement cementation in different directions and at different positions.By making a cement cementation model,designing different cementation conditions,testing the instrument,and the quality of the first and second interface cementation can be accurately determined.At the same time,through the filling of oil,gas and water medium in the interface gap position,the chart board of amplitude curve of oil,gas and water medium is established.The results show that the sonic amplitude has good correlation with the interface gap.The method can be used to identify the location of the annulus clearance and the oil,gas and water medium contained in the clearance,which has certain guiding significance for field logging interpretation.
