摘要: 辽西凌源–宁城盆地牛营子地区钻探的辽凌D1井，在中元古界高于庄组发现了油气显示。系统地分析了高于庄组烃源岩的地球化学特征，研究结果表明：烃源岩饱和烃中正构烷烃分布基本完整，呈明显的单峰态前峰型，具有C27规则甾烷优势，指示了有机质来源以低等水生生物贡献为主；较高的孕甾烷相对含量和C19~C29三环萜烷/C29~C35藿烷比值，以及较高的甾烷和升藿烷成熟度参数值，均表明烃源岩出于成熟阶段；而低的Pr/Ph和较高伽马蜡烷含量指示了偏还原的沉积环境。
Abstract: Well LLD1 was drilled in Niuyingzi Area of Lingyuan-Ningcheng Basin in the west of Liaoning Province. Oil and gas indications were found in the Gaoyuzhuang Formation in the Mesoprotero-zoic. The geochemical characteristics of the source rocks were systematically analyzed in the study. The results indicate that the distribution of n-alkanes series in saturated hydrocarbons is substantially complete in all source rocks with an evident unimodal pattern. The distribution of C27~C29 regular steranes presents a dominance of C27 steranes, indicates a predominantly aquatic organisms input in the organic matter of relative source rocks. There exist high relative contents of pregnane and C19~C29 tricyclic terpane/C29~C35 hopane ratio, as well as maturity parameters related to steranes and hopanes; it also indicates that all source rocks are matured. Moreover, a lower (Pr/Ph) ratio and relatively high gammacerane concentration indicate an anoxic deposition environment of partial reduction.
