| 摘 要： | 特低渗透断块油藏的几何形状以及流体非线性渗流特征都对井网部署有影响。针对不同几何形状的特低渗透断块油藏设计了不同形式的注采井网,以江苏油田花17断块为例,在考虑流体非线性渗流特征的前提下,应用研发的非线性渗流数值模拟软件对每种井网形式进行了开发效果评价。研究表明,对于可以部署两排直井的条带状断块油藏,注水井“隔一布一”地正对采油井部署的方式相对最优;小型条带状油藏选择水平井采油直井注水时,注水井的相对最优位置为水平井井趾的外围;对于可以部署少量直井的小三角形油藏,注水井置于采油井排外侧有利于提高开发效果。此项研究为特低渗透断块油藏的井网优化提供了一种新方法。

| Abstract: | Arrangement of well pattern in a extra-low permeability fault-block reservoir is affected by its geometry and nonlinear flow features.Taking Hua-17 block in Jiangsu oilfield as an example,different well patterns are designed in view of its different geometries,and the nonlinear flow features are considered.Then the development effect of each well pattern is evaluated using the nonlinear flow numerical simulation software.The results show that for the banding-like fault block reservoirs that two rows of vert... |
