多分支井生产动态分析

由于分吱井特殊的井身结构，其生产动态明显不同于直井。利用数值模拟技术，模拟各种形态的多分支井的生产动态，模拟结论为油藏压力从油藏边界到主井筒逐渐降低；在靠近井的部位，等压面形状类似于分支井的形状；越向外缘扩散，等压线的变化趋势更加缓慢，形状类似泄油边界；异侧分支井优于同侧分支井；泄油面积随分支角度的增大而增大。这些为分支井的形态优化和油藏开发方案的制定提供必要的理论依据。

Production Performance Analysis of Multilateral Well

Because the Multilateral Well have a peculiar cas-ing programme,its production performance distinct from straight well.Using numerical simulation techniques simulated production performance of different multilateral well.The simulation conclu-sion was reservoir pressure phase down from reservoir limit to main hole;near the hole,the shape of the isopiestic surface had analogy to the shape of multilateral well;as it to the outer edge,the varia-tion of isobaric line became slowly and its shape was similarity w...
