摘要
根据油藏特征,利用经济分析和数值模拟手段,研究了渤海油田聚合物驱油藏筛选指标的技术经济界限,把该地区适宜聚合物驱油蔹细分为4类。潜力评价表明,渤海油田整体聚合物驱平均提高采收率可达5.92%,其中Ⅰ类和Ⅱ类油藏聚合物驱的技术经济指标较好、潜力大、风险性小。目前,在渤海油田开展的聚合物驱矿场试验取得了明显的控水降水和增油效果,Ⅰ类和Ⅱ类油藏聚合物驱将成为该地区常规稠油提高采收率的主要技术方向。
The tools of economic analysis and numerical simulation were used to research the technical-economic limit of reservoir screening index for polymer flooding in Bohai oilfields,and the reservoirs suitable to polymer flooding were divided into 4 types.A potential evaluation has indicated that the recovery efficiency can averagely increase by 5.9％ for the overall polymer flooding in Bohai oilfields,with Type Ⅰ and Ⅱ reservoirs being higher in the technical economic index,greater in potential and lower in risk for polymer flooding.Currently,the field tests of polymer flooding in Bohai oilfields resulted in significant effects in controlling and reducing water cut and increasing oil production.The polymer flooding for Type Ⅰ and Ⅱ reservoirs has been the main direction of enhanced oil recovery technology in conventional heavy oil reservoirs,Bohai Sea.
