摘　　要：为提升油田开发效果,通过数值模拟的方法研究油田井网优化问题。以等腰直角三角形油藏为例,对断块稠油油藏直井、直井与水平井组合的10种井网形式进行注采井网部署,比较分析累计产油量、净产油量、油汽比、采出程度等钻采指标,筛选出最佳井网形式。研究表明,直井与水平井组合井网的开发效果优于直井井网,直井注汽、水平井采油的井网形式更适用于稠油油藏。This thesis aims to improve the development effect of small triangle fault-block heavy oil reservoir by numerical simulation. It sets the isosceles right triangle reservoir as an example to research the injection-production pattern deployment for ten kinds of well pattern of vertical and vertical-horizontal well combination by numerical simulation methods in this reservoir. And the cumulative oil production,net oil production,steam-oil ratio and recovery ratio are calculated and compared,thus the best effective pattern is screened out. The result shows,the development effect of combined pattern of vertical and horizontal wells is better than vertical pattern,and the well pattern of vertical well steam injection and horizontal well production is more suitable for this kind of the heavy oil reservoir.
