摘要
通过对莫深1井三叠系暗色泥岩进行有机地球化学与岩石学分析,研究了有机质丰度、类型和成熟度,并评价了其生烃潜力。结果表明,三叠系暗色泥岩有机质丰度为0.17%～9.11%,平均值1.62%,达到了高丰度有机质标准;有机质来源以高等植物为主,类型为II2到III型;有机质热演化进入成熟演化阶段;三叠系可能是潜在的烃(特别是气)源岩系。鉴于已有工作对三叠系的生烃潜力研究较少,所以本文认识为区域油气深入勘探提供了基础参考新信息,并可供国内外同类研究作对比参考。
According to the organic geochemical and petrological analyses on Triassic mudstones from Well MS 1,the organic matter abundance,type and maturity are revealed.And the hydrocarbon generative potentialis addressed and evaluated.The results show that the organic matter abundance is between 0.17%～9.11% and the average value is 1.62%,reaching the standard of high-quality source rock.The organic matter are mainly derived from higher plant,the kerogen type is from II2 to III.The organic matter has gone into mature stage.Thus,the Triassic mudstones are favorable for hydrocarbon(especially gas)generation.Considering that the source rock potential of the Triassic strata has not been well constrained,this study provides a new reference information for regional oil and gas exploration nationally and internationally.
