摘要
新海27块属厚层-特厚层边底水普通稠油油藏,由于测井系列及开发初期对储层认识程度的制约,主力小层d1I13层内夹层分布及对开发控制作用一直未被引起重视。通过对储层沉积特点的分析,提出采用声波时差作为本区层内夹层识别的主要手段,并结合动态试采资料加以印证,应用该方法对层内夹层分布特征进行重新评价,并部署四口水平井挖掘夹层控制的剩余油潜力。
Block Xinhai27 is a thick and ultra thick conventional heavy oil reservoir with edge and bottom water. Owing to restriction of logging series and recognition degree of reservoir, distribution of interlayer and its control function are not emphasized. Based on sedimentary feature analyzing of reservoir formations, it’s proposes that acoustic time logging is the main method adapting to interlayer identification in this area, and verifies by production test data. It’s evaluates the distribution of interlayer by using this method again, implements four horizontal wells to remaining oil controlled by interlayer.
