缅甸伊洛瓦底盆地22°凸起区发育始新统塔本组和朗欣组烃源岩,塔本组泥质烃源岩是区内主要烃源岩,为中等-好烃源岩;提林组、塔本组和蓬当组砂岩是该地区的主要储集层,总体具有中-低孔低渗的特征;以塔本组泥岩为烃源岩,塔本组砂岩为储层,塔本组上段稳定泥岩层为直接盖层,可构成塔本组自生自储式储盖组合,是主要的勘探层系。综合评价认为该区具有较大的勘探潜力,Patolon-Daungtaik构造带为最有利的勘探区带。
In the 22 ° bulge area of the Burma Irrawaddy basin, the Eocene Tarim Basin and Longxin Formation source rocks are developed. The Tarim source rocks are the main source rocks in the area and are medium-good source rocks. The main reservoirs in this area are the Linzhan Formation, Tadamu Formation and Puntaandu Formation sandstone with the characteristics of medium-low porosity and permeability; the Tarim Group mudstone is the source rock, the Tadun Formation sandstone is the reservoir and the tower The upper stable mudstone in this group is a direct cap rock, which can form a self-generated self-storage reservoir cap assemblage in this group and is the main exploration strata. The comprehensive evaluation shows that the area has great exploration potential, and the Patolon-Daungtaik tectonic belt is the most favorable exploration zone.
