摘　　要：宝浪油田宝北区块储层属于典型的低孔低渗而且伴有强烈的非均质性,前期投入注水开发时没有充分发挥储层的产油能力,产量递减速度加快。流动单元是评价储层质量及开发效果的强有力手段。鉴于宝浪油田流动单元方面的研究已有一定的基础,油田开发调整一方面需要在新井布置上尽量符合流动单元的空间分布,另一方面需要努力探索不同流动单元最优组合开采的可能性。本文在本区流动单元研究的基础上,利用数值模拟方法对不同的流动单元组合开采方式进行简化模拟,通过分析注入孔隙体积倍数、含水率、单位孔隙体积采油速度、采出程度之间的关系,确定本区流动单元最优开采组合方式为流动单元B与流动单元C组合开采,流动单元D单独开采。这一结果将对油田经济高效开发具有重要的现实意义。The reservoir in block Baobei of Baolang oilfield belongs to typical low-porosity and low-permeability reservoir with serious heterogeneity. The oil producing capacity of the reservoir is not fully realized at early waterflood development stage and the production declined fast. Flow unit is the most efficient method to evaluate the quality and development effect of the reservoir. Considering that the flow unit in Bao Lang oilfield is widely studied, the oilfield de-velopment adjustment not only requires the coincidence between new well arrangement and spatial distribution of flow units, but also requires the probability study of optimum production combination mode of different flow units. Based on the study of the flow units, production combination mode of different flow units are simplified simulated by numerical simulation. Based on the analysis of the relationships among injection pore volume, water content, unit pore volume production rate and degree of reserve recovery, combination of flow unit B and flow unit C is the optimum production combination mode, and flow unit D need independent production. The results have an important practical meaning to develop oilfield efficiently and economically.
