摘要

辽河西斜坡油田生油岩的 DPEP/ETIO 值随井深增大而降低

ETIO 与卟啉总量之比随井深增大而增大。油页岩卟啉以 DPEP 为主

DPEP/ETIO 值不随埋藏深度而变。根据卟啉含量及类型

可将我国原油分为4类。

Abstract

Porphyrins in crude oils

source rocks and oil shales in China are mainly DPEP and ETIO.With the increase of burial depth

the ratio DPEP/ETIO of source rocks decreases gradually and high-carbon-number porphyrins(D

)change into low-carbon-number ones.But the ratio DPEP/ETIO of oilshales does not change with burial depth.According to the contents and types of porphyrins

the chinese crude oils can be divided into 4 kinds:biodegradedoil

immatured oil

matured oil and higher matured oil.
