对延吉盆地东部含气区的预测

PREDICTION TO GAS - BEARING AREAS IN EAST PART OF YANJI BASIN

本文通过延吉盆地东部大一、二段现今气势能的计算及气势能场的空间分 布特征，对延吉盆地东部大一、二段有利含气区进行了预测，指出章岩洞——南阳地区 是天然气聚集的最有利地区和勘探的重点地区；西山、东风、兴安和东盛涌地区也可以 形成天然气聚集区，但难以形成大规模的天然气聚集，是天然气勘探的较有利地区。

According to spatial distribution characteristics of gas potential energy field, this paper predicts the favorable gas - bearing areas of the first and second members of Dalazi Formation in the east part of Yanji basin by calculating the nowadays available gas potential energy of the first and second members of Dalazi Formation, pointing out that Zhangyandong Nanyang areas are the most favorable natural gas accumulating areas and important exploration areas; natural gas accumulating areas can also be formed in Xishan, Dongfeng, Xing' an and Dongshengyong areas but not in a large scale, these areas are relatively favorable natural gas prospecting areas.
