摘要: 赵县青斜是冀中地区新近发现的含油构造,其构植面积70km2,探明原油地质储量1300×104t。在滚动勘探开发研究过程中,应用油藏综合描述技术,进行了构造精细解释、砂体预测及成藏条件研究,分析了油气富集的控制因素及分布规律.指出了赵县背斜发育有构造油藏、岩性-构造油藏、构造-岩性油藏3种类型,并建立了成藏模式。该成果对于复杂断块油气藏的滚动勘探开发、对于赵县背斜的进一步开发具有指导意义。Abstract: The Zhaoxian anticline is a new oil-bearing structure discovered in 1998, with 1300×104t of oil reserve. The total area of the anticline is 70km2 and trap area 55.2km2. During the progressive exploration and development, the anticline was studied in detail and the control factors on formatim and distribution of oil pools were clearly definited in accordance with reservior description. Three kinds of oil pools were classified, including structural, lithological-structural and structural-lithological oil pools. The study may provide some valuable suggestions for future exploration and development of the anticline.
