摘要: 为了研究侧积层对注采结构的影响,以渤海L油田南区高弯度曲流河储层为研究对象,在砂体构型精细解剖的基础上,确定了储层构型模式对流体运动的影响方式,建立了曲流河储层构型机理模型。通过数值模拟从侧积层孔隙度、渗透率、厚度、产状、水平宽度及地层倾角等6个方面研究了储层构型模式对流体运动的控制作用,回归了曲流河储层构型控制系数的经验公式。根据B-L水驱油理论推导了受储层构型影响的水驱波及系数表达式,并建立了基于曲流河储层构型的注采结构矢量调整图版。结果表明:曲流河点坝中的侧积层对流体运动的控制作用不随侧积层孔隙度增加而改变;侧积层对流体运动的控制作用随着侧积层渗透率的增加而减弱;侧积层厚度、水平宽度、分布频率、地层倾角的增加均会使侧积层对流体运动的控制作用增强。应用注采结构矢量调整图版对渤海L油田南区D12井组进行优化调整后,日产油累计增加了123 m3/d,调整效果显著,为后续优化注水及储层构型控制下的剩余油精细挖潜奠定了基础。

Abstract: In order to study the effect of lateral layer on the injection-production structure,taking the high-curvature meandering river reservoir in the southern part of Bohai L oilfield as the research object,the influence of reservoir architecture on fluid flow was determined based on fine anatomy of sand body configuration,and the reservoir architecture model of meandering river was established. The control effect of reservoir architecture model on fluid flow was studied from the aspects of porosity,permeability,thickness,occurrence,spreading range and formation inclination by numerical simulation. The empirical formula of reservoir control coefficient of meandering river reservoir was established by regression. According to B-L water flooding theory,the expression equation of water flooding sweep coefficient affected by reservoir architecture model was deduced,and the vector adjustment chart of injection-production structure based on meandering river reservoir architecture model was established. The results show that the control effect of the lateral layer on the fluid motion in the meandering river dam does not change with the increase of porosity of the lateral layer. The control effect of the lateral layer is weakened with the increase of the permeability of lateral layer. Increasing the thickness,horizontal width,distribution frequency and formation angle of the lateral layer can enhance the control effect of the lateral layer on fluid flow. After optimizing the D12 well group in the southern Bohai L oilfield by using the injection-production structure vector adjustment chart,the daily oil production increased by 123 m3/d,and the adjustment effect was remarkable,which laid a foundation for further optimization of water injection and tapping of remaining oil under the control of reservoir architecture.

Key words: meandering river, reservoir architecture, lateral layer, control coefficient, vector water flooding, reservoir numerical simulation, injection-production structure structure
