俄罗斯感应测井仪与国产双感应测井仪的对比及其应用

Contrast of Russian Made Induction Log Tool with A Chinese One and Their Applications

2004年中国石油测井长庆事业部从俄罗斯引进了2套H-IKZ-2型感应测井仪,为了配合该仪器在长庆油田的推广,对其测井资料进行了初步的分析研究。采用交会图技术将俄罗斯感应测井仪的深探测(IR4A)电阻率与BSJ801双感应八侧向测井仪的深感应(R ILD)电阻率在不同电阻率储层中的响应值进行了对比,找出了二者之间的差异;在处理参数相同的情况下,将2种深探测电阻率计算的含水饱和度与岩心分析含水饱和度进行了对比和分析;最后,以实例的形式分析了孔隙度、渗透率等储层参数对俄罗斯感应测井仪的影响及其应用效果,总结出了初步的定性解释方法。

Basic analysis and study on the log data are conducted on an application evaluation. Cross-plot technique is used to compare the deepest resistivity response readings IR4A recorded by H-IKZ-2 with RILD recorded by current market popularly accepted induction tool DIFL(Dual Induction Focused Log, model BSJ801) in various formations. With same type processing and interpretation parameters inputs, corresponding water saturation calculated by the above deepest resistivity logs is given, these outputs are compared and analyzed with core estimated saturation. Several application cases are presented to evaluate Russian induction log in porosity, permeability and other formation parameters determination. A preliminary qualitative interpretation method is concluded.
