摘要
钻探证实渤海海域沙河街组生物碎屑灰岩（白云岩）是油气高产储层。在对渤海钻遇沙河街组碳酸盐岩的68口井的钻井、测井、试油资料进行统计和对碳酸盐岩钻遇深度、厚度、岩性、岩石结构、沉积相、含油气情况、孔隙度、层速度、构造位置等资料参数研究的基础上，总结出了生物碎屑灰岩发育特点，并对QHD30－1、BZ25－1和BZ25－1北构造等进行了分析，推测了其碳酸盐岩的分布范围与储集特征。
Exploration demonstrates the bioclastic limestone (dolomite) of Shahejie formation is one of the high production reservoir in Bohai area. The study of depth, thickness ,lithology, porosity,velocity, sedimentary facies and petroleum production of the set of reservoir has been done based on the statistics of drilling,log and oil test data of 68 wells. The results will be helpful to the prediction of the distribution and reservoir properties in the QHD30-1 ,BZ25-1 and BZ25-1N structures.
