准东探区白垩系油气主要受阜康凹陷侏罗系烃源岩的控制 ,平面上主要沿阜康凹陷周边分布 ,纵向上油气主要分布在白垩系中下部。白垩系构造面貌是由南西向北东方向抬升的大斜坡 ,构造圈闭不发育。沉积相研究结果表明有利的相带主要集中在五彩湾凹陷—沙丘河、北三台地区 ,而该地区油气的保存条件相对较差。综合分析认为北三台西斜坡—阜康断裂带西段是准东白垩系今后的主要勘探目标区
The Cretaceous hydrocarbon in the quasi-east exploration area is mainly controlled by the Jurassic source rocks in the Fukang sag, mainly distributed along the periphery of the Fukang sag in the plane and mainly distributed in the middle and lower Cretaceous. The Cretaceous tectonic topography is a large slope uplifted from southwest to northeast, with undeveloped structural traps. Sedimentary facies results show that favorable facies belts are mainly located in the Wucaiwan Depression - Duqiuhe and Beisantai areas, while oil and gas reservoirs in this area are relatively poorly preserved. The comprehensive analysis shows that the western section of the Beisantai west slope-Fukang fault zone is the main exploration target area of the quasi-East Cretaceous in the future
