摘要
黄骅坳陷中旺-齐家务地区沙一下亚段油气显示活跃,储层岩性主要为生物灰岩,油井产量高,具有良好的油气勘探潜力,近些年该区勘探工作逐步取得成效,对油气成藏的认识进一步完善。钻井资料揭示港西、孔店凸起周缘普遍发育生物灰岩,基于油源对比,识别出中旺次洼、歧北斜坡沙一下亚段和中旺次洼沙三段烃源岩为生烃母质,并结合断层活动和原油密度分布,判断长期活动的断层油气运移通道。油气成藏模式分析研究认为,该区齐家务背斜生物灰岩为首要油气勘探目标,其次为中旺次洼断阶带云灰质页岩,据此指导该区部署井位2口,探索生物灰岩低成熟度油气。
The Shayixia formation of Zhongwang-Qijiawu area of Huanghua depression shows active oil and gas,and the main reservoir lithology is biological limestone.The oil well production is high,and it has good oil and gas exploration potential.In recent years,the exploration work in this area has been successful and the process of hydrocarbon accumulation has been further understood and improved.According to drilling data,it is revealed that biolimestone is widely developed around Gangxi and Kongdian uplift.Based on oil-source correlation,the source rocks of Zhongwang sub-sag,Qibei slope Shayixia and Zhongwang sub-sag,Shahejie three member are identified as their parent material.Based on fault activity and crude oil density distribution,the long-term active fault oil and gas migration channels are determined.The analysis of oil and gas accumulation model shows that the biological limestone of Qijiawu anticline in this area is a principle oil and gas exploration target.It is followed by cloud gray shale of Zhongwang sub-sag fault stage,which guides the deployment of two wells in this area to explore the low maturity oil and gas of biological limestone.
