摘要
以沉积学、油田地质学等为基础，并且结合钻井、试油及分析化验资料，进行大洼-海外河地区复式油气聚集带的石油地质特征综合评价，分析其成藏模式。结合表明：丰富的油源条件、广泛发育的多套储集体，多种类型圈闭及油气沿大洼断裂带两侧运移的主要指向，使本区具备了油气富集条件；在构造和沉积作用控制下，使大洼－海外河地区各种油气藏在平面上广泛分布，在空间上按不同层次，具有一定成因联系的不同类型油气藏有规律地组合在一起，形成大洼－海外河地区复式油气用集带。
On basis of sedimentology, oil field geology, accompanying with drilling well, oil well test and experi mental data, the geological characteristics of complex oil and gas belt in Dawa-Haiwaihe area was analysed and their accumulation pattern was proposed. It was indicated that there were rich source rocks, well de veloped multiple set of reserviors, various traps in the area. Under structural and depositional controls,various hydrocarbon accumulations were widely developed and a complex oil and gas belt with different oil and gas reserviors was formed in the area.
