【摘要】 江陵盐盆在石油勘探中陆续发现了多处富钾卤水,其卤水中KCl含量达到17～19g/L,在对卤水层勘查中,尝试利用地球物理资料进行富钾卤水层追踪。勘查的方法为:首先由卤水层段伽马与波阻抗交会图得出卤水层的波阻抗特征,进而利用三维地震资料对卤水层进行识别与追踪,并最终圈定富钾卤水层分布范围。江陵凹陷沙市组卤水层勘查实践表明,充分利用石油勘探资料,特别是钻井和地震资料,有望取得找钾的新突破。更多还原

【Abstract】 Oil expLoration in the JiangLing basin have been discovered many potassium-rich brine,the brine in the KCl concentration to 17～19g / L.On the exploration,geophysical data attempt to use potassium-rich brine layer tracking.ExpLoration methods: first by the brine layers impedance crossplot gamma obtained impedance characteristics of the brine layer,then use three-dimensionaL seismic data on the brine layer identification and tracking,and ultimately the distribution delineated the scope of K-rich brine layer.Through the use of seismic data to track the brine layer Shashi JiangLing depression,showed that the full use of petroLeum exploration data,in particular,drilling and seismic data,is expected to achieve new breakthroughs in potash.更多还原
