摘　　要：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.A new concept of petroleum sub\|system is put forward in this paper. The division principles, structure models and evaluation method for the sub\|system are proposed. The weighted distribution values of the elements forming oil and gas reservoir corresponding to oil and gas sub\|systems are obtained. Based on the division of oil and gas system of Tuha basin, the oil and gas reservoir in the northern depression of the basin in Jurassic system is divided into eight sub\|systems. According to the high potential interface of flow in the basin, the component elements of the sub\|systems are weighted and evaluated. A new comprehensive evaluation method for these sub\|systems is suggested by calculating the weighted mean values of the component elements of the sub\|systems. The results of comprehensive evaluation are in good agreement with those of exploration.
