摘要
大港油田历经40多年的勘探,已经进入成熟区岩性油气藏勘探阶段。成熟区的油源、储集、圈闭等条件均较优越,但成熟区构造及油藏关系复杂,因此成熟区勘探应采用斜坡区岩性勘探的思路和工作流程,重新认识和评价成熟区的分析研究工作,要在充分利用成熟区丰富钻井资料的基础上,开展储层精细研究,包括层序划分、岩相识别以及剖面上和平面上的储层刻画。实践证明,对成熟区岩性油气藏勘探的再认识应用效果十分明显,从而打开了成熟区勘探的新局面。
Dagang oilfield has experienced more than 40 years' exploration and has entered into lithologic oil/gas exploration stage of maturing zone. The source, accumulation and trap conditions in maturing zone are superior, but relationship between the structure and reservoir in maturing zone is complex, therefore, the ideas and work flow of lithologic exploration in slope area should be adopted for exploration in maturing zone. During re-knowing and evaluating the analyzed works in maturing zone, it should, on the basis of fully using abundant drilling data in maturing zone, develop fine study of reservoirs, including partition of stratigraphic sequence, identification of lithologic facies and description of reservoir on plane. The practice achieved distinctive effects, opening up a new prospect for exploration in maturing zone.
