黑龙江东部晚三叠世-早侏罗世放射虫硅质岩特征及油气远景

古生代放射虫硅质岩地层中富含浮游相生物化石，这些化石中的脂类物质和有机质在地层中往往形成海相烃源岩而富含油气资源.目前在此类地层中已开采出大量油气，有些地区已成为世界上有名的顶级大油田.在勘探工作中发现黑龙江东部晚三叠世-早侏罗世存在大量的放射虫硅质岩地层.过去未将此类地层列入勘探目标，研究认为此类地层将会成为一个潜在的油气勘探目标.

CHARACTERISTICS OF THE T3-J1 RADIOLARIAN CHERT AND POTENTIAL FOR HYDROCARBON IN EASTERN HEILONGJIANG PROVINCE

The Mesozoic radiolarian cherty strata contain abundant planktic microfossils,which provide rich lipid and organic materials commonly associated with marine hydrocarbon source rocks rich in oil and gas. Large amounts of hydrocarbon have been extracted from such strata. Some of them have become famous major oil fields. A lot of radiolarian cherty is found in the T3-J1 strata in Eastern Heilongjiang Province during recent geological survey, although previous exploration was not targeted at these strata for oi...
