摘要
三孔隙度测井资料在深层火山岩气层显示较弱,从而使三孔隙度测井资料识别深层火山岩气层较困难。本文提出视标准层差值法识别深层火山岩气层,该方法消除岩性、泥质和井眼的影响,突出气层与标准层的差别,放大地层含气信息。通过实际应用证实,视标准层差值法能很好地指示深层火山岩天然气层的信息。
Three porosity log curves are weak in the deep natural gas in volcanic rock, so it is difficult for the three porosity log curves to identify the deep natural gas in volcanic rock. This paper proposes a method about using standard layer to identify the deep natural gas in volcanic rock. The method eliminates the impact of lithology, muddy and hole, distinguishes the differences between natural gas and standard layer and magnifies the information about the natural gas in the deep volcanic rock. The practical application of the method shows that it can indicate the existence of natural gas in the deep volcanic rock.
