摘要/Abstract

摘要： 油藏的各向异性对油田开发过程中的井网布置和油井产能具有重要影响，常规规则井网不能很好地适应各向异性油藏，渗透率主方向油井见水时间短，而渗透率侧方向储层水驱效果不佳或油井未见效。为解决该问题，突破传统的常规规则井网形式，根据水驱油的流管法原理和物质平衡方程，构建平面各向异性油藏菱形反九点井网。当边井和角井见水时间相等时，各向异性油藏可以达到均衡驱替的效果。根据各向异性油藏的基本特征，建立了各向异性油藏菱形反九点井网合理注采单元几何参数的定量计算公式，并通过实例对所建立公式进行了验证。在各向异性油藏中，短轴角井井距随着长轴角井井距的增加而增加，随各向异性系数的增加而迅速降低，在各向异性系数为10时，短轴角井井距的减小趋于平缓。新的菱形反九点井网提高了油藏的采出程度和注入水的波及效率，为平面各向异性油藏构建合理的九点井网提供了理论依据。

Abstract: Reservoir anisotropy permeability has an important effect on the well pattern and oil well capacity during the oilfield development process. However, the normal well pattern is not suitable for the anisotropic reservoir, and the oil well water breakthrough time in the main permeability direction is short. However, the water flooding in the side permeability direction is poor or the oil well is not swept. In order to solve this problem, we break through the traditional well pattern, based on the water flooding stream tube method and material balance equation, and build up the nine spot well network of planar anisotropic reservoir. In this paper, when the water breakthrough time of edge well and corner well is equal, the reservoir can achieve the balance flooding effect. According to the basic characteristics of anisotropic reservoir, this paper establishes the calculating formula of geometric parameters of reasonable injection and production unit of nine spot well network. And the formula is verified by examples. In the anisotropic reservoir, the shorter corner well spacing increases with the increase of the longer corner well spacing and decreases rapidly with the increasing anisotropy coefficient. When the anisotropic coefficient is smaller than 10, the corner well spacing decreases slowly. The new diamond inverted nine-spot well pattern improves reservoir recovery and sweep efficiency of injected water. This paper provides the theoretical basis and guidance for planar anisotropic reservoir construction of nine spot well pattern.

Key words: anisotropic reservoir, permeability, nine spot well pattern, water breakthrough time, well spacing
