本世纪五十年代以来,山东半岛沿岸海面经常发现漂浮的原油团块,其大小不等,小者如拳头,大者如桌面。1959年在威海—成山头间发现过上百斤的大油块,黑褐色、具可塑性、有油味,经取样鉴定为原油。这些油块多在刮偏北风时出现,风浪把它激荡在沿岸的沙滩或峭壁上,很引人注目。这些原油的来源一直受到地质工作者的关注。1975年国务院环保部门 Since the 1950s, floating oil clumps often found in the sea off the coast of Shandong Peninsula have varied sizes, with small ones such as fists and large ones such as the desktop.
