摘要

摘要: 综合应用地质、钻井、地震和地球化学资料,系统分析了安达地区构造演化、烃源岩、沉积、储盖组合、油水关系及油藏类型和油气成藏特征,研究了本区的石油地质特征,认为烃源岩有机质丰度高,具有较好的生、排烃能力;分流河道砂体储层物性好,为油气聚集提供较好的储集空间;良好的储盖组合有利于油气的聚集与保存;油源断裂为油气的运移提供了重要的通道;青山口组一段泥岩超压为油气的运移提供了动力。研究区总体呈下水、上油的油水分布特征,以断层—岩性和岩性—构造油藏为主。区内扶余油层油气成藏受成熟烃源岩、青山口组一段超压、优势运移通道和储集条件控制。根据上述认识明确了研究区下一步的勘探方向,有效地指导了该区的油气勘探。

Abstract: Based on geologic, drilling, seismic and geochemical data, it was analyzed in this paper the tectonic evolution, source rock, sediment, reservoir-cap combination, oil-water relationship as well as accumulation type and characteristics in Anda region. Petroleum geologic features in the region were concluded as follows. Organic matter abundance of source rock is high, favorable for hydrocarbon generation and migration. Physical properties of sandbody reservoir in distributary channel are good, providing room for hydrocarbon accumulation. The favorable combination of reservoir and cap rock helps hydrocarbon accumulation and preservation. Fracture which leads to source rock works as pathway for hydrocarbon migration. Overpressure in mudstone in the 1st member of the Qingshankou Formation drives hydrocarbon to migrate. In the study area, water locates at the bottom and oil locates at the top. Reservoirs are mainly fault-lithology and lithology-tectonic ones. The Fuyu oil layer in the region is controlled by mature source rock, overpressure in the 1st member of the Qingshankou Formation, favorable migration pathway and reserve condition. Further exploration target in the region was pointed out.
