摘要

根据东营凹陷王46、莱深1、柳参2等孔二段烃源岩样品地球化学特征分析, 为

中— 差等烃源岩。为了全面认识孔二段烃源岩地化特征, 利用孔二段烃源岩实测分析资料, 建

立了测井信息烃源岩评价模型, 并运用该模型对孔二段烃源岩有机碳含量( TOC )、氢指数

(H I )及成熟度( R0 )等进行了系统评价。孔二段烃源岩TOC 为0.5% ~ 2.4%, 干酪根以Ⅱ—————

Ⅲ型为主, R0 为0.72% ~ 1.32%, 表明有机质处于成熟— 高成熟阶段, 综合评价为一套中等—————

好烃源岩, 是东营凹陷又一套具有巨大生烃潜力的烃源层。

Abstract

The Ek2 sou rce rocks arem edium and poo r g rade, wh ich
is estim a ted by the geo chem ica l da ta of the Ek2 sam ples
co llected from theW e llsW ang 46, Laishen 1 and Liucan 2 in
the Dongy ing depress ion. In o rder to fu lly know about theEk2
source rocks character istics, we bu ild up the logg ing
estim ation m ode l about source rocks on the basis of the
geochem ica l data o f the Ek2 source rocks. The conten t of the
estim ation inc ludes som e param eters such as the conten t of
o rganic carbon, the index of hydrogen and the ma turation.
The va lue o f content of org an ic carbon in Ek2 source rock is
from 0. 5% to 2. 4%. The type o fⅡ - Ⅲ o rganic ma tter is
predom inant in the Ek2 sou rce rock. And the value of the
m atura tion is from 0. 72% to 1. 32%, wh ich indicates that
the o rganic m atter is in the stage o f m aturate - high ly
m atura te. In conc lusion, the Ek2 sou rce rocks wh ich are
m ed ium and prem ium hav e large po tential in genera ting
hydrocarbon.
