摘　　要：潜山披覆构造带周边缓坡带既是油气运移通道 ,又可形成各种圈闭类型的油气藏。利用精细油藏描述技术寻找剩余微型圈闭油藏并使之形成生产能力 ,是勘探成熟区滚动勘探开发的重要工作。文章分析了埕东凸起南部缓坡带成藏特征 ,指出了“过路油”微型圈闭油藏的控制因素 ;通过变速成图、约束反演等技术实现了缓坡带的精细构造成图以及储集层横向预测 ;总结出五种低幅度微型圈闭油藏类型。该项研究有效地指导了埕东油田周边地区的滚动勘探开发 。Peripheral gentle slope belt of drape structural belt of buried hill is the oil?gas migration pathway, and it can form various trap types of reservoirs. Using delicate reservoir description to look for residual miniature trap reservoirs, and making it productivity are an important task of rolling exploration and development at mature exploration area. Reservoir forming characteristics of the gentle slope belt in south of Chengdong arch are analyzed in this paper. It is pointed out the controlling factors of “by?passed” oil miniature trap reservoirs. Delicate structural mapping of the gentle slope belt and lateral forecasting of the reservoirs are realized by using the technology of “variable speed mapping”, constraint inversion and so on. Five kinds of miniature trap reservoir with low amplitude are summarized. This research effectively guided the rolling exploration and development of peripheral areas of Chengdong oilfield and has achieved good results.
