摘　　要：前人研究认为盐池侏罗系成藏受控因素为古地貌单元,丘咀及斜坡为有利的成藏部位,经过近年来的勘探开发,目前发现的多个侏罗系延c以上出油井点受古地貌控制作用不明显,高地部位发现多个出油井点。同时受天环坳陷与西缘逆冲带的共同影响,侏罗系具有成藏条件复杂,油藏规模小,隐蔽性强,产建方向难以把握的特点。急切的需要重新系统总结成藏规律,有效指导下步勘探增储及产能建设工作。Previous studies have concluded that the controlled factors of the Jurassic reservoir in Yanchi are ancient geomorphological units, and the hilly and slope are favorable sites for the formation of reservoirs. After exploration and development in recent years, many Jura extended 8 or more oil wells have been discovered. The control effect of ancient geomorphology is not obvious. Multiple wells were found in the highlands. At the same time, due to the influence of the Tianhuan depression and the western margin reverse impulse zone, the Jurassic system has the characteristics of complex reservoir formation conditions, small reservoir size, strong concealment, and difficult to grasp the direction of production and construction.The urgent need to systematically summarize the reservoir-forming law and effectively guide the next exploration and storage and production capacity construction work.
