摘　　要：从东营凹陷孔店组早期盆地构造沉积研究出发,分析研究孔二段及暗色泥岩空间分布及其生油指标,进而对其生烃潜力及油气资源量进行评价和预测。济阳坳陷孔二段主要发育于东营凹陷的中北带地区和博兴洼陷,暗色泥岩发育面积为1000～1300km2;干酪根类型主要为Ⅱ1—Ⅲ型,有机质含量为0.91%～0.99%,镜质体反射率为0.85%～1.58%,为中等烃源岩,按有机碳质量平衡法计算东营凹陷孔二段烃源岩的生烃总量为7.1×108t,具有巨大的勘探潜力。Based on the early basin structure character in Kongdian formation,distribution in space and oil generation index of Ek2(Kong Ⅱ member)formation and dark mudstone were researched,and the hydrocarbon generation potential and resources volume were assessed and predicted.Kong Ⅱ member in Jiyang Depression developed in the mid-north zone of Dongying Depression and Boxing Sag,with 1 000-1 300km2 of dark mudstone area.It is moderate hydrocarbon source rock with kerogen Ⅱ 1 to Ⅲ type,organic content from 0.91% to 0.99% and Ro value from 0.85% to 1.58%.According to mass balance method of organic carbon,the total hydrocarbon generation weight of Ek2 source rock in Dongying Depression is about 7.1×108t which has giant exploratory potential.
