【摘要】 针对塔中4油田422高点CⅢ油组(TZ422CⅢ油组,以下简称CⅢ油组)的开发现状,在充分考虑地层非均质性、沉积相分布的基础上,利用Eclipse模拟软件E100主模块的精细油藏数值模拟,对研究区水驱后剩余油的分布进行了定性与定量研究,并给出CⅢ油组3种井网调整方案。结果表明,CⅢ油组采用直井和水平井相结合的井网调整方案,最佳注采井网共18口,新井4口,老井14口,并对最佳方案模拟到2025年,最终采收率为46.13%,综合含水为89.06%。更多还原

【Abstract】 Based on the current status of the development in TZ422CⅢ oil group,the residual oil distribution after water flooding was investigated qualitatively and quantitatively using fine reservoir numerical simulation of E100 main module.According to the sedimentary facies map,considering the formation heterogeneity and sedimentary facies distribution,three deferent types of well network regulation schemes are designed.The result indicates that the well pattern which the vertical well and the horizontal well unify is used in CⅢ oil group.The best injection-production pattern of 18 wells with 4 new wells,14 old wells.The preferred scheme is simulated to 2025,the final recovery efficiencyis 46.13%,and the composite water cut is 89.06%.更多还原
