Sonic Scanner在新疆油田的应用分析

论文摘要

声波测量广泛用于油井的整个生命过程,早期的声波测量方法相对较为简单,只是将地震信号与岩层进行对照拟合。Sonic Scanner声波扫描仪是由斯伦贝谢公司推出的新一代阵列声波测井仪器,利用最新的声波技术进行多种频率扫描信号的采集,主要涵盖交叉偶极子和多种距离单极子的测量结果。该仪器具有耐高温、耐高压、能量更强、频带更宽、测量模式多样、采集信息量更大、探测地层信息更为精确、信噪比更高、方位阵列更全、可适用于各种尺寸井眼等特点,使得该仪器在地质应用方面更为广泛,包括岩石力学属性分析、地层各向异性分析、寻找裂缝带、计算渗透率、评估井眼稳定性、识别气层等;同时,通过快、慢横波频散图分析,了解裂缝是否张开及其延伸情况,进而判别裂缝的有效性,以期为储层有效性评价及后期储层压裂改造提供依据。本文通过对Sonic Scanner声波扫描仪的性能介绍以及在新疆油田应用情况,希望能够进一步提高对这套设备的认识,为后续的推广应用提供参考。
