摘    要:对临清坳陷东部地区地温及其影响因素进行了研究,并分析了下第三系烃源岩有机质的热演化特征.指出本区地温梯度低,生油层埋藏浅,致使下第三系各生油层经受的最高温度和有机质成熟度明显偏低,主力生油层尚处在主要生油阶段的早中期,难以生成大量成熟油气,从而影响了本区的油气勘探成效

关 键 词:地温梯度  烃源岩  有机质成熟度  油气勘探  临清坳陷

Abstract:Because the lower Tertiary source beds are of shallow burial and smaller geothermal gradient, the level of maturity of organic matter in the source rocks of the east part of Linqing depression is obviously lower than that of adjacent depression. Organic matter in the major source bed is still in the early and middle stages of thermal maturation. The relative shortage of petroleum source is considered as a main reason for the lower achievement of petroleum exploration in this area.
Keywords:Geothermal gradient  Source rock  Organic matter maturity  Oil and gas exploration  Linqing depression
