【摘要】 通过对鄂尔多斯盆地油房庄油田定31井区长1油藏精细地质建模,对该区油田地质储量、采油量、含水率和压力等方面进行了数值模拟,在此基础上,对剩余油分布规律进行了研究,认为剩余油主要分布在构造高部位、沉积主河道注水未波及部位、生产井泄油半径之外和生产井未补孔层位。针对剩余油不同的分布形式,制定了新钻调整井和老井侧钻、注采井网完善、采油工程挖潜3种方法进行开发方案调整,对调整后的开发指标进行预测,结果表明油气藏数值模拟对开发方案的调整有指导意义。更多还原

【Abstract】 Through fine geologic modeling of Chang 1 reservior of Ding 31 well area in Youfangzhuang oil field, numerical modeling is set on geologic reserve, oil production, watercut and pressure in the area. On this basis, residual oil distribution is researched, mainly on structurally high part, main channel deposits not flooded, oil sewed semidiameter of well and production well which is not perforation.To various distribution patterns of residual oil,3 methods are developed to production adjustment, including new adjustation well and sidetracking of old wells, perfection of injection-production pattern, production engineering potential development. The estimation of production index indicates that numerical modeling and production adjustment are effective.更多还原
