根据系统理论,提出了亚含油气系统的概念,阐述了亚含油气系统的内涵.根据亚含油气系统组成特点,构造了亚含油气系统评价的结构模型,提出了应用层次分析法评价亚含油气系统的方法,给出了亚含油气系统组成要素相对亚含油气系统贡献的权值.在对吐哈盆地含油气系统划分的基础上,应用流体高势面,在平面上将盆地北部凹陷带中下侏罗统含油气系统又划分出8个亚含油气系统.通过对各亚含油气系统组成要素的自身评价与权重加权,做出了各亚含油气系统的最终评价,其评价结果与勘探实际吻合良好,为盆地下步油气勘探提供了科学依据.
According to the system theory, the concept of sub-oil-bearing gas system is put forward, and the connotation of sub-oil-bearing gas system is expounded. According to the characteristics of sub-oil-gas system, structural model of sub-oil-gas system evaluation is constructed. Gas system, and gives the weight of contribution of sub-petroliferous system components to the sub-petroliferous system.On the basis of the division of petroleum system in Turpan-Hami basin, using the high potential surface of fluid, With the middle-lower Jurassic petroleum system divided into 8 sub-petroliferous systems.According to the self-evaluation and weighted weighting of the sub-petroliferous system components, the final evaluation of each sub-petroliferous system was made and the results of the evaluation Which is in good agreement with the actual exploration and provides a scientific basis for further exploration of oil and gas in the basin.
