摘要:
水平分支井已?成为开发边际油藏、常规稠油油藏、低渗透油藏、裂缝油藏、高含水油田剩余油挖潜的重要手段,也已经成为研究热点。首先研究了常规稠油油藏水平分支井渗流特征,在对水平分支井生产段(主支和分支)进行数学描述的基础上,利用势叠加原理,并考虑了各分支之间以及与主支之间的干扰,推导出油藏与生产段耦合条件下,常规稠油油藏对称水平分支井和非对称水平分支井的产能评价数学模型。并且将该模型应用于渤海常规稠油油田水平分支井产能计算,计算结果与该井投产后的实际产量误差在20%以内。
Abstract:
As a research hotspot, the horizontal multilateral well has been an important technology used to exploit marginal reservoirs, heavy oil reservoirs, low permeability reservoirs and naturally fractured reservoirs, and produce residual oil in high water-cut oilfield. This paper first studies the mechanism of percolation characteristics of horizontal multilateral wells in conventional heavy oil reservoir. Then based on the mathematical description of production section(main branch and branch) of horizontal multilateral wells, it develops the mathematical model of productivity evaluation for the symmetrical and unsymmetrical horizontal multilateral wells in terms of the coupling of reservoir and production section, according to the theory of potential superimposition, considering the interference among different branches. The model applied to productivity calculation of horizontal multilateral wells in Bohai conventional heavy oil oilfield and deviation between practical production rates and prediction results was below 20%.
