蠡县斜坡中南部油气分布与成藏模式研究
|
摘要
蠡县斜坡中南部勘探程度相对较低,对已知油藏的油气富集规律和成藏模式认识不清,以往认为该区主要以"阶梯式"运移成藏模式为主,但与实际油藏的分布存在矛盾。经过对斜坡中南部的断层活动期次和沉积体系的研究,认为该区垂向输导受晚盛晚衰断层的控制,为连通砂体提供了油气侧向输导途径。综合分析已知油藏的分布并进行油源对比研究,可以得出斜坡中南部的成藏模式具双油源、长距离、多层位、浅层平行运聚的特点。根据这一特点指明了下一步滚动勘探的方向和思路,即"立足找浅层,地震寻构造,精细画岩性"。
The exploration degree in middle-south part of Lixian Slope is relatively low,making the hydrocarbon distribution pattern and hydrocarbon accumulation model of the known reservoirs unclear.It is assumed that the hydrocarbon accumulation model is mainly "stepped-like",but this model conflicts with the distribution of reservoir.Through comprehensive study of faults activity phases and depositional system,we conclude that the late developed and late ended faults control the vertical migration path,while connected sand bodies provide lateral migration path for oil and gas.Combining the distribution of known reservoirs and research of oil-source correlation,we find that the hydrocarbon accumulation model in middle south part of Lixian Slope is characterized by dual source,long distant migration,multi-oil-bearing zone and shallow formation parallel migration.This model provides the direction and clue for further exploration and development,which is"based on shallow formation;finding subtle structure trap by finely seismic interpretation and determining sedimentary micro-facies accurately."
