选择了对济阳坳陷东营凹陷南坡低熟油形成具有意义的未熟钙质页岩进行模拟实验 ,并分别研究了可溶有机质和干酪根演化产物的地球化学特征 ,建立了可溶有机质、干酪根产率特征及相互关系 .首次计算出了半咸水湖相沉积环境中可溶有机质和干酪根早期降解对未熟油形成贡献的比率 ,在未熟油成因机理的研究中取得了进展 . We chose to simulate the immature calcareous shale that formed on the south slope of the Dongying Sag in the Jiyang Depression, and studied the geochemical characteristics of the organic matter and kerogen evolution products, established the soluble organic matter, Kerogen yield characteristics and their relationships, the ratio of soluble organic matter and kerogen degradation to the immature oil formation in the sedimentary environment of the semi-saline lacustrine was calculated for the first time, and progress has been made in the study of the genesis mechanism of immature oil.
