摘要:
高邮凹陷ZW油田垛一段6号砂层组为高含水、高采出程度的“双高”开发单元,剩余油分布零散、复杂,开发后期仍存在局部剩余油富集。为定量识别和描述剩余油富集区域,通过对密闭取心井岩心、化验数据、测井等资料的深入分析,结合研究区66口井测井曲线特征、钻井取心资料及生产动态的综合评价,分析影响剩余油分布的主要地质因素。认为微构造高点和小断层遮挡处剩余油较富集;纵向上正韵律控制的小层顶部剩余油富集程度较低,但整体物性较为一致,因此韵律影响作用有限;物性稍差储层与隔夹层是控制研究区剩余油分布的最主要地质因素,在上有隔层、下有夹层的配置下,两者在平面上的展布区域即为剩余油有利挖潜区。
Abstract:
The E2s16 Formation of Zhenwu Oilfield in Gaoyou Sag is a “double-high” development unit with high water cut and high recovery, the distribution of remaining oil is scattered and complex, and local residual oil enrichment still exists in the late development stage. To quantitatively identify and describe the remaining oil rich regions, through in-depth analysis of the core, test data, and logging data of closed coring wells, combined with the comprehensive evaluation of the logging curve characteristics, drilling coring data, and production performance of 66 wells in the study area, the main geological factors affecting the residual oil distribution were analyzed. It is concluded that the remaining oil is more enriched at the high points of microstructures and the shelters of small faults; the remaining oil is less enriched at the top of the small layers controlled by positive rhyme in the vertical direction, but the overall physical properties are still relatively consistent, so the effect of rhyme is limited; the slightly less physical reservoir and the interlayer are the most important geological factors controlling the distribution of remaining oil in the study area. Under the configuration of the barrier on the top and interlayer on the bottom, the distribution area of the two on the plane is also the favorable area for tapping the potential of the remaining oil.
