摘　　要：利用有关孔隙度和有机质热成熟度的理论公式研究了二者之间的内在联系,建立起Ro与砂岩孔隙度之间的关系模型.用该模型对济阳坳陷沾化凹陷渤南洼陷沙河街组四段上亚段烃源层有机质的成熟度进行了估算,指出该烃源层有机质已达到成熟.Some inherent linkage between sandstone's porosity and the thermal maturity of organic matter has been studied using the theoretical formulae, and a relationship model is established between R o (vitrinite reflectance) and porosity of sandstone. In Bonan subsag within Zhanhua sag, Jiyang depression, the model has been used to calculate the organic maturity of Upper Member 4 source rock, Shahejie Formation, suggesting that the source rock has been mature.
