摘要：

济阳坳陷是中生代以来的一个近海块断坳陷,是渤海湾盆地的一部分,面积约为25000平方公里。中新生代湖相沉积总厚度可达5000—12000米,纵向上具多旋回性,有10套含油气层系。湖盆发育的全盛时期是渐新世,沉积物主要是沙河街组三段中、上部的还原深湖相沉积。丰富的有机质和良好的埋藏、转化条件,使这一层系具有生成油气的巨大潜力。

Abstract:

14 specimens of representative immature source rocks of Oligocene from Jiyang depression in Shandong Province and 16 samples of peat soil and muck from Jilin,the East China Sea,the Bohai Bay,Weishan Lake and Futong River are studied through factor analyses,including R-type and Q-type analyses,and correlative analyses on the basis of 28 geochemical indexs,to identify the correlativity among samples and/or indexes. Results of this study show that the organic matters of Oligocene in Jiyang depression have the characteristic of near-shore fault-block bounded lacustrine basin with continental organic matters mixed with a little marine organic mat-ters.It has been proved that when this type of organic matters reaches sufficiently enough quantity in a matured environment,commercial oil and gas may be generated.
