塔北隆起西部火山岩储集层空间格架的地球物理响应
|
摘要
玄武岩储集层空间格架具有期次性、韵律性和旋回性。在野外玄武岩储集层地质模型的基础上,结合井下岩心和岩屑分析结果,利用玄武岩储集层在测井和地震上的响应特征,精细识别和划分塔北隆起西部玄武岩储集层的空间格架。每个期次底部对应的柱状节理玄武岩声波时差值小,密度大,深浅侧向电阻率值大且基本重合,向上声波时差值变大,密度减小,电阻率值逐渐变小,反映从下到上岩石的孔隙度逐渐变好,与气孔玄武岩、气孔杏仁玄武岩对应;地震剖面上玄武岩对应的同向轴振幅较强,连续性较好,内部为平行反射,成层性非常好。流纹岩储集层期次性和韵律性不明显,但可识别出较大的旋回,每个旋回由凝灰岩、流纹岩组成,凝灰岩井段电阻率值减小,密度减小,声波时差值增大,反映了凝灰岩疏松的物性特征,可以作为旋回的界限;地震剖面上流纹岩表现为内部反射杂乱,振幅中等,连续性较差,但旋回清楚。
The structure of basalt reservoir is cyclic,rhythmical and periodic.Based on the geological model of basalt outcrops and the chemical analysis of drilling cores and cuttings,the geophysical behaviors of underground basalt can be used to identify these structural features of basalt reservoir in western Tabei Uplift.The column joints in the lower part of each eruptive period has low DT value,high density value,high and overlapped ILD and ILM values;as to vesicular and amygdaloidal basalt of the middle and upper part,DT value increases,density,ILD and ILM values go down,which reflect good porosity in each period.The basalt reservoir has high amplitude,parallel reflection configuration,good continuity and stratification in seismic responses.In rhyolite reservoir,only cycles can be identified,without obvious eruptive periods and rhythms.Each cycle of the rhyolite reservoir is comprised of rhyolite and tuff.Tuff can be regarded as the boundary of each cycle.Compared with rhyolite,tuff has lower density,ILD and ILM values,and higher DT value.Rhyolite reservoir has moderate ampitude,chaotic reflection configuration,bad continuity,clear cylce in seismic responses.
