苏北探区火山岩油气藏类型研究
|
摘要
苏北探区火山岩广泛发育,在横向和纵向上变化较快,成藏规律复杂多样,给油气勘探带来较大困难。通过分析烃源岩、储集层和盖层的匹配特征,并结合地震资料,研究了苏北探区火山岩与烃源岩和围岩的接触关系,同时对该区火山岩成藏模式进行了研究,总结了6种类型的火山岩油气藏成藏模式,包括烃源岩与火山岩间接接触型、烃源岩与火山岩直接接触型、火山岩被烃源岩包裹型、烃源岩与火山岩上下接触型(上下供烃)、火山通道顶部成藏型、岩墙隔挡型;并对古近系阜宁组和三垛组的火山岩油气藏进行了预测,归纳为3类火山岩油气藏,分别为生储关系为包裹接触型(近源型)、生储关系为上下型(近源型)及油气靠断裂运移(远源型)的油气藏。
Being widely developed in Subei exploration area,volcanic rocks are characterized by fast lateral and vertical change,complicated accumulation rule,which causes great difficulties for oil and gas exploration.By analyzing source rocks,matching characteristics of reservoir and cap rock,combining with seismic data,this paper studied the contact relationship of volcanic and source rocks,and studied the volcanic reservoir accumulation model.There are six types of reservoir accumulation model,including indirect contact of source rocks and volcanic rocks,direct contact of source rocks and volcanic rocks,volcanic rocks enwrapped by the source rocks,source rocks developed on and below the volcanic rocks,volcanic reservoir developed on the top of volcanic conduit and volcanic rocks acted as seal.These reservoir accumulation models were used to predict the volcanic reservoir at the Funing and Sanduo formations in Eogene.Totally,they can be summed up to three types of volcanic reservoir,including the relationship of source and reservoir represents as enwrapping(near source rocks),the relationship of source and reservoir shows as up and down(near source rocks),and faults act as the main hydrocarbon migration path.
