摘要
介绍了胜利石油管理局测井公司新研制成功的多极子阵列声波测井仪器采集的数据结构类型。研究了多极子阵列声波测井资料的处理方法。用矩阵、相位等处理方法得到地层纵波、横波、斯通利波时差,利用偶极资料进行快慢横波分离,有效计算地层横波速度各向异性。胜利油田3口井的实际应用表明多极子阵列声波测井资料与其他测井资料相结合,可进行油藏评价,如井眼稳定性分析、地层孔隙压力预测、压裂施工压力设计及缝高检测等。实际钻井资料证明多极子阵列声波测井资料在油田勘探、开发中能够发挥重要作用。
Introduced are the data recording structures of multipole array acoustic logging tool developed by Shengli well logging company recently. Studied are the processing methods for multipole array acoustic log data. The compressional wave slowness, shear wave slowness, and Stoneley wave slowness are obtained from matrix algorithm, phase shift algorithm and other related processing methods. The anisotropy of shear wave velocities is calculated effectively by separating fast and slow shear waves from dipole data. The actual application in 3 wells in Shengli oilfield shows that we can do reservoir evaluation such as borehole stability analysis, formation pore pressure prediction, fracturing design and fracture height detection by combining multipole array acoustic log data with other log data. Practical drilling data show that multipole array acoustic log data play an important role in reservoir exploration and development.
