摘要
北马庄油田是一个复杂断鼻油田,油层分布受断层和岩性共同控制,单油砂体呈条带状分布,油层含油高度小,含油带窄,储层物性较差,储量计算比较困难。通过对该区进行油藏描述,落实了构造形态和储层展布,扩大含油面积1.4km2,增加89×104t石油地质储量,指出了下步挖潜的有利勘探区块。
Distribution of pay zo nes in Beimazhuang oilfield,a complex fault nose oilfield,is controlled by bot h faults and lithology;individual sandbody has zebra distribution;oil column is short and narrow;and reservoir physical proper-ties are poor.Therefore,re serves estimation is difficult.More accurate structural shape and distribution are deter-mined through reservoir description leading to additional oil-bearin g area of1.4km 2 and additional geologic reservesof890,000t.
