在党的领导下,近两年来我们在灰岩的科研和生产上都取得了一定的成果,先后研制出了适用于灰岩的密度测井仪和井眼补偿声波测井仪,为灰岩油气田的扩大勘探做了一定的工作。在济阳凹陷薄层灰岩无论在纵向抑或横向上分布均很广泛。在纵向上,下第三系五个含油层段(DY,S1,S2,S3,S4)中均有碳酸盐岩沉积,但以 S1和 S4段最为发 Under the leadership of the party, we have made some achievements in the research and production of limestone in the recent two years. We have developed density logging tools and borehole compensation acoustic logging tools for limestone. Expansion of oil and gas exploration done some work. The thin-bedded limestone in Jiyang sag is widely distributed both vertically and laterally. Longitudinally, there are carbonate sediments in the five oil-bearing intervals (DY, S1, S2, S3, S4) of the lower Tertiary, but the most developed is the S1 and S4 segments
