通过对哈拉哈塘组薄砂体开展小层精细划分对比、沉积亚相—微相研究、储层预测等工作，研究砂体展布范围及规律；在前期实钻资料的基础上，井震结合对构造进行精细解释；通过岩心观察、分析化验、测井评价等资料的分析，结合已试采井动、静态资料，对目的层圈闭进行综合评价，落实有利圈闭并进行储量计算；开展老井复查工作，落实砂体含油气性，为下步老井措施挖潜提供依据。

The fine description of thin layer, sedimentary subfacies and microfacies analyses and reservoir prediction have been made in thin sand body in the Halahatang Formation of the Upper Triassic in the Tahe Oil Field. The range and rule of sand body distribution have been concluded. Based on previous actual drilling data, the fine interpretation of structure has been made combined with seismic analysis. Through core sample observation, analysis and well logging evaluation, combined with dynamic and static data from producing well, the traps in target layers have been evaluated. Favorable traps have been pointed out and reserves have been calculated. Some old wells have been reviewed. The petroleum-bearing capacity of sand body has been judged, providing basement for the further exploration of old wells.
