摘要
利用噪声频谱测井识别管外或地层内流体的流动类型和特征,可以弥补常规生产测井只能识别管内流体流动特征的缺点,噪声频谱测井与常规生产测井相结合,在油气田开发中具有广泛用途。伊拉克多个油田的地质、油藏和完井投产情况复杂多变,不同服务公司的噪声频谱测井技术在不同条件下应用效果呈现较大的差异性。实践表明噪声频谱测井的应用效果在砂岩储层优于孔隙型碳酸盐岩储层,在单层管柱井段优于多层管柱井段,在高产或高注入量井优于低产或者低注入量井。分析总结噪声频谱测井在伊拉克油田的应用实例,将为该项测井技术的推广应用提供借鉴。
As a compensation of production logging tool(PLT)which can only measure the flowing inside tubing or casing,spectrum noise logging(SNL)can detect matrix flowing outside the completion string.It is very useful to combine PLT with SNL for a wide application in oilfield production phase.Commercial SNL tools from different companies have been applied in Iraq’s oilfields where geology,reservoir,and completion strings are different.Field observation seems to be diversified in different conditions.Generally,SNL is more suitable to be used in sandstone reservoir than in carbonate reservoir,simpler in single completion string than in multilayer completion strings,and stronger signal to noise ratio in high flowrate well than in low flowrate well.The experience in utilization of SNL in Iraq’s oilfields can be a reference for applications of this technology in other fields.
