摘要
根据不同沉积微相中砂体对注入水的不同影响,从A地区以III24层四口井所处的相带为代表分析了不同沉积微相上注水井与油井之间的水体运动特点,认为分流河道砂体渗透率最好,注入水流动速度快但不均匀,沿着河道路径快速突进,而河口砂坝、薄层席状砂等微相的砂体渗透率较低,水体流动速度较慢但比较均匀,并为该地区不同沉积微相上注水提出建议。
Based on the influence of different sedimentary microfacies to injection water from the theory,four wells in III24,A-area are analyzed in this paper to investigate the water's movement between injection well and oil well,which locate in different sedimentary microfacies. The studies show that because of the good penetration,the water in distributary channel travels quickly along the river path while not evenly and the water in mouth bar or the leading edge thin sand travels slowly and evenly. Three suggestions on injection under different sedimentary microfacies are put forward in the end.
