根据任丘古潜山油藏任观６井１９８０年至１９９５年１５年时间内６次深侧向电阻率时间推移测井资料，结合该油藏先期注水、后期降压开采的生产实际进行了系统的分析解释，对潜山内部剩余油分布规律得到了一些新认识：（１）致密层遮挡的微细裂缝发育段油气可以重新聚集；（２）岩块自吸驱油过程是一个漫长的历史阶段；（３）降压开采措施的实施加速了潜山内部油气的再聚集；（４）阻隔层遮挡的内幕高部位可能形成剩余油富集区 According to the logging data of deep lateral resistivity time series of Well 6 in Renqiu buried hill reservoir in Well Renqiu from 1980 to 1995 for 15 years, combined with the early waterflooding and post-buck production in this reservoir, According to the systematic analysis and explanation, some new understandings have been obtained for the distribution of the remaining oil in the buried hill: (1) the fine fractures obscured by the tight layers can be re-aggregated; (2) the spontaneous recovery and flooding of rocks is a long history Stage; (3) the implementation of step-down mining measures to accelerate the re-aggregation of oil and gas inside the buried hill; (4) the high position of the obstruction hidden inside the barrier may form the remaining oil-rich area
