人们对事物本质的认识

往往从现象开始。我们对麻江古油藏的认识

是从对志留系含沥青砂岩的调研开始的。一贵州东部的麻江、都匀、丹寨、凯里一带

在志留系翁项群第二段(S

1-2

)中

广泛而稳定地分布着一套形象十分特殊的"黑砂岩"。细察之

其黑色并非导源于砂粒本身

实因其粒间充填物黑色所致。此填充物为何?是否石油的变异产物?其历史演变怎样?

Recently

the black sandstone in the 2nd member of Wengxiang group(S

1-2

)in Majiang

Duyun

Dangzhai and Kaili regions in eastern Gui-zhou was studied by detailed field survey and a lot of laboratory tests

and was discoverde no other than bituminous sandstone. The bitumen

with which the pore spaces between asnd grains are filled

is a variation of petroleum.
