摘要
自然伽玛能谱测井曲线数据真实地反映了泥质含量的变化,而泥质含量的旋回间接地反映了海平面的升降旋回。TH值曲线和K值曲线与泥质含量有良好的相关性,而且通过对自然伽玛能谱测井曲线数据进行处理,可得到TH/U、U/GR、TH/U值曲线,根据TH值曲线、K值曲线、TH/U、U/GR值的变化旋回来划分层序和体系域。自然伽玛能谱测井曲线应用于长兴组碳酸盐岩地层层序划分中,取得了良好的效果。
Natural gamma energy spectrum logging data reflected the shale content,and shale content cycle indirectly reflect the rise and fall of the sea level.TH value curve and K value curve and shale content has the good correlation,and through the natural gamma energy spectrum logging curve data processing,we can get TH/U、 U/GR and TH/U value curve,according to TH value curve,K value curve,TH/U and U/GR value change to differentiate of sequence and systems tracts.Natural gamma energy spectrum logging curve is applied to Changxing group carbonate stratigraphic sequence in the division,and good effects were obtained.
