摘　　要：大港油田港北斜坡区由于产量较低且零星分布,多年来一直未有突破。该区地震资料品质较差,存在构造落实难、储集层预测难、油气成藏控制因素认识不清等问题。从钻井资料出发,利用新的地震资料,在层序划分基础上,运用相干数据体、三维可视化等技术进行精细构造解释,并开展储集层预测及综合地质分析。研究认为,该区受多幕构造运动的影响,发育多期不整合,主要存在地层不整合遮挡、地层超覆等地层岩性油气藏。针对此类油气藏开展精细描述,共部署井位45口,完钻41口,其中39口取得成功并先后投产,获得了很好的地质效果和经济效益。Due to the area production of Gangbei slope in Dagang Oilfield is low and scattered,there has been no breakthrough over the years.The seismic data quality of the area is poor,the implementation of the structures and reservoir prediction are difficult,and the understanding of control factors for oilgas reservoir forming is unclear.Starting from the drilling data and using new seismic data,based on the sequence division,the fine structural interpretation,reservoir prediction and comprehensive geological analysis were carried out by using coherent data volume,three-dimensional visualization technology.Studies suggested that the area was affected by the multi-episodic tectonic movements,developed multiphase unconformity with unconformity shelter,stratigraphic overlap and other stratigraphic-lithologic reservoirs.Fine descriptions were carried out for such reservoirs,deploying 45 wells,among them 41 wells were drilled,where 39 wells have been put into operation successfully and achieved good geological effects and economic benefits.
