精细构造解释及储层预测技术在龙西地区的应用
|
摘要
大庆油田龙西地区以常规油气勘探为主,纵向上多层位含油,剩余资源丰富,油藏类型多样,具备挖潜基础,但该区勘探程度较高,油藏规模小、分布零散并且隐蔽性强,发现难度大。在重新深化成藏认识的基础上,充分发挥GeoEast解释系统的技术优势,采取纵向细化、横向放大的研究方式,多技术联合应用,形成精细断层、微幅构造识别及精细储层预测配套技术,落实小断层及微幅构造圈闭,精细识别构造、岩性及构造—岩性复合圈闭,优选有利钻探目标,已完钻的多口井获得高产。
Conventional oil exploration has been mainly conducted in the Longxi area,Daqing Oilfield.There are still abundant residual oil and gas in multiple formations although the area has been explored and developed for many years. However oil bearing beds in the area are characterized by small sizes, scattered distributions, and subtle feature,and they are very difficult to be predicted. To obtain new understanding of reservoirs, we carry out reservoir research with interpretation tools provided by GeoEast. Stratigraphic units are subdivided and analyzed with vertical and lateral magnification. A number of interpretation techniques are used in combination. And fault identification, low relief structure identification, and reservoir prediction are achieved. Minor faults and subtle traps are accurately identified. A few drilled wells based on our proposal yield high oil production.
