摘　　要：紧临生油洼槽的箕状凹陷斜坡带,是油气运移的主要指向,也是油气富集的主要场所。由于以往对斜坡带的认识较为局限、研究技术方法较单一,华北油田斜坡带的总体勘探开发程度相对较低。在对华北油田斜坡带油气富集规律进行总结的基础上,提出了斜坡带的评价方法。通过对斜坡带成藏规律的再认识,利用精细构造描述、滚动式储层预测以及大位移多靶点斜井钻探等技术,在文安斜坡、蠡县斜坡等区带的油藏评价工作取得了突破,不仅丰富了斜坡带成藏模式和油气富集规律,也积累了大量有效的工作手段和经验,以期对同类型区带的评价研究提供借鉴。The dustpan-like sag slope, which is close to the oil-generating depression, is the main point to the oil and gas migration. Also, it is the main place for oil and gas accumulation. Because of limited awareness and simple research method on the slope formerly, the overall exploration and development level of the slope in Huabei Oilfield is still relatively low. Based on the summary of oil and gas enrichment law in the slope of Huabei Oilfield, an evaluation method for slope was proposed. On the basis of further understanding of oil and gas accumulation law in the slope, the reservoir evaluation in slopes, such as Wen an Slope, Lixian slope, etc, has made outstanding achievements by using technologies such as fine structural description, roll- ing displacement reservoir prediction and extended reach multi-target well. The work has improved oil and gas accumulation model in the slope, enriched understanding of the accumulation law, and accumulated lot of working experience. It will provide references for evaluation and study of the same type zone.
