摘要： 辽河油田 A区块储层的沉积发育状况呈现复合韵律, 油层中间层段渗透率高, 根据储层存在高渗透层的实际情况, 为有效利用水平井注蒸汽挖潜剩余油, 需要对水平井的位置、 水平段轨迹层位、 水平段长度及注气参数进行优化。应用P e t r e l建模软件和CMG油藏数值模拟软件, 建立了研究区的精细地质模型, 在历史拟合基础上
对水平井的位置、 水平段长度、 水平段距高渗层距离以及注气参数进行优化。研究结果表明, 水平井注蒸汽通过蒸汽上覆作用, 蒸汽到达高渗透层后, 在高渗透层快速水平突进, 并以较大接触面积向上继续加热油层, 最终可以实现油层纵向上的均匀波及。数值模拟结果显示, 优化后的水平井能更有效地开发油层中的剩余油。

Abstract: Development of the reservoir in A block of Liaohe oilfield present compound rhythm reservoirs, high permeability layer among the reservoir, according to the real situation that high permeability layer exist, for the efficient utilization of producing remaining oil by horizontal well, that need to optimize locations, trajectory, length of horizontal well and vapor injection parameters. A fine geological model which reflects the characteristics of the reservoir in studied area was constructed with Petrel and CMG software. Optimize locations, trajectory, length of horizontal well and vapor injection parameters upon the history matching. The research result shows that steam override, after reaching high permeability layer, the steam makes fast breakthrough in high permeability layer, keeping on upward heating the reservoirs with large contact area. Finally the reservoirs can be uniformly swept in the vertical direction. The numerical simulation accurately predicts the optimized horizontal well can effective exploit the residual oil.
