摘    要:化学动力学模型在黄骅坳陷的应用表明,研究区的丛粒藻、菌解有机质及可溶有机质中的非烃、沥青质的确能在浅于常规生油门限的埋深条件下开始大量生烃。在此基础上,结合区内烃源岩的分布、厚度、埋藏史及烃源岩的地化特征和残烃特征所进行的定量评价表明,孔店南区孔二段生成和排出的未熟—低熟油量分别为34.5×108t和31.9×108t,歧口西区沙一下分别为13.4×108t和9.4×108t,两层位所提供的油资源量(包括成熟油)分别为7.1×108t和2.8×108t。这意味着,孔店南区孔二段应该能导致小而肥的未熟—低熟油聚集,而与区内沙一下有关的地区和层位的勘探潜力也值得重视。这同时也表明,从化学动力学理论出发,进行未熟—低熟油生成、排出量及资源量的评价,不仅理论上可信,而且实践上可行。

关 键 词:黄骅坳陷  未熟油  低熟油  资源评价  化学动力学

Abstract:The application of chemical kinetic models in Huanghua Depression indicates that the botryococcus, organic mater (OM) reworked by microbe and soluble OM (non-hydrocarbon and asphatene) in the research region do begin to generate hydrocarbons in large amount at shallower buried depth relative to the normal threshold of oil generation. Combined with the distribution, thickness, and buried history of source rocks as well as their geochemical characteristics and feature of residue hydrocarbon, the quantitative evaluation shows that the amounts of hydrocarbon generation and expulsion for the 2nd member of Kongdian Formation are 3.45 billion tons and 3.19 billion tons respectively in the south region of Kondian,and that for the 1st member of Shahejie Formation are 1.34 and 0.94 billion tons respectively,the amounts of oil resource (including mature oil) of the 2nd member are 0.71 and 0.28 billion tons respectively. This means that the 2nd member of Kongdian Formation in south Kongdian will results the enrichment of oil accumulation of immature to low-mature oil, and the exploration potential related to the 1st member of Shahejie Formation is not negligible. These also suggest that it is both reliable and workable to evaluate the amount of generation and expulsion as well as the resource of immature to low-mature oil from the chemical kinetic theory.
Keywords:Huanghua Depression  immature oil  low-mature oil  resource evaluation  chemical kinetics
