摘要
ThruBit偶极声波测井仪器是斯伦贝谢公司ThruBit过钻头测井系统新型的声波测井仪器,能同时采集全波及交叉偶极横波信息,在复杂井眼条件下能获取优质的地层弹性波信息。结合ThruBit偶极声波测井仪器结构及数据特点,研究基于该仪器的全波慢度提取、全波能量提取以及各向异性反演的处理方法,利用该方法在四川盆地页岩地层处理了30余口井的偶极声波测井资料。通过自主开发的软件模块有效解决了利用ThruBit偶极声波测井仪器资料处理及页岩气储层评价问题,为页岩气的勘探开发提供了有力支撑。
The ThruBit dipole acoustic logging tool is a through-bit logging tool developed by Schlumberger.It can collect full-wave and cross-dipole shear wave information at the same time,and obtain high-quality formation elastic wave information in a complex borehole.Based on the structure and data characteristics of the ThruBit dipole acoustic logging tool,the processing method for extracting full-wave slowness,full-wave energy and anisotropic inversion was developed and has been applied for processing the dipole acoustic data from more than 30 wells drilled in the shale formation in the Sichuan basin.And using the proprietary software module solves the issues arising out of processing the data recorded by the ThruBit dipole acoustic tool for shale gas reservoir evaluation,providing a strong support for exploration and development of shale gas.
