摘要
针对疏松砂岩油藏开发中后期优势通道普遍存在、目前优势通道定量模拟的方法比较缺乏、不能满足剩余油精细挖潜研究需要的现状,在充分考虑油藏静、动态资料的基础上,提出了运用模糊综合评判方法定量描述和模拟优势通道的方法。该方法参考单井点处优势通道发育指数和出砂量,修正地质模型中优势通道所在网格的各向传导系数和有效渗流孔隙体积,实现了优势通道的定量模拟。在高浅北区应用结果表明,该方法有效表征了优势通道的发育及其对流体渗流的影响,为优势通道流体运动控制及剩余油精细挖潜提供了基础。
At late periods of the loose sandstone reservoir development,preferential migration passage is universal.While at present,the quantitative description method for preferential migration passage is rare and it cannot meet the needs of remaining oil fine tapping research status.In full consideration of reservoir dynamic and static data,the fuzzy comprehensive evaluation method for quantitative description and simulation has been put forward.In reference with single well point of preferential migration passage,development index and sand production volume,the conduction coefficient and the effective seepage pore volume can be amended,and it can realize the quantitative simulation of preferential migration passage.The application results show the effect of preferential migration passage development on fluid seepage flow,and the method provides basis for fluid movement of preferential migration passage and fine tapping of remaining oil.
