【摘要】 目前国内大部分油田已进入开发中后期,随着开发的不断深入,用合理有效的方法寻找并挖潜剩余油显得尤为重要。开展储层精细描述、单砂体内部建筑结构及其内部流动单元研究,分析剩余油分布规律,为油田调整开发方案及增产助采提供有利依据。本文通过精细的储层沉积学理论,对榆树林油田东14水平井井区杨Ⅰ组厚砂层进行了水平取心井岩心归位及精细描述,井区内垂向井震结合高分辨率层序地层、平面沉积微相、空间储层分布研究。在此基础上,对水平井水平取心段河道砂体所在曲流点坝进行单砂体内部建筑结构研究,为油田进入高含水期、多次井网加密后的三次采油阶段揭示出了更为复杂的储层内部结构,反映出非常强的储层非均质性,结合目的层剩余油的研究,总结出储层内剩余油的分布特征,为持续、高效开发油田,提高采收率具有重要的现实意义。更多还原

【Abstract】 At present, the domestic majority of oil fields entered the development mid and late part, along with development unceasingly thorough, seeking for and tapping latent potentialities the remaining oil with the reasonable effective method appears especially important. The development reservoir fine description, the internal sandbody architecture and the internal flow unit research, and then remaining oil distribution rule analysis, helps for the oil field adjustment development program and the production increase picks provides the advantageous basis .This thesis adopts the fine reservoir sedimentology theory, has carried on horizontal core homing and the fine description, high resolution sequence stratigraphy of vertical well and earthquake in well field, surface sediment microfacies, reservoir distribution in space studies of YI thick sandstone of east 14 horizontal well block in Yushulin oil field .Based on this, regarding channel sandstone of meandering channel bar, there are horizontal well in which carries on the internal sandbody architecture studies. That revealed more complex reservoir internal architecture, reflected very strong reservoir heterogeneity for tertiary recovery stage, which has entered the high watery time, the multiple well pattern thickening .Combined with remaining oil research in subject reservoir, this paper sumed up distribution feature of reservoir remaining oil, brought vital practical significance for the continuate and highly effective development oil field and oil recovery enhancment .更多还原
