Several Aspects on Hydrocarbon Generation of the Ordovician Source Base on Petroleum Geochmical Features

Zhao Mengjun; Liao Zhiqin; Huang Difan; Xiao Zhongyao

Marine Ordovician strata are an important hydrocarbon source in worldwide, and were studied bymany foreign workers.Now, oil and gas exploration for the Ordovician as a Source stratum has been ad-vanced for recent several years, for example, some oilfields have been found in Tarim Basin,of which oilsare from the Palaeozoic source, especially the Ordovician.The generation of hydrocarbons of the Ordovi-cian source is different from that of Mesozoic nd Cenozoic sources since there were on high plants in the Ordovician Period.In the article, several sapects on generation of hydrocarbons of the Ordovician sourcewere discussed base on geochemical features of Ordovician oilsin the world.And it is hoped that this dis-cussion may draw people' s attention to the generation of hydrocarbons of Ordovician strata.
