Analysis of Influences of the Reservoir Anisotropy on Productivity of Herringbone Multi-lateral Well
摘要
Abstract
In order to study the influences of reservoir anisotropy on the productivity of herringbone multi-lateral well, based on the theory of coordination conversion, anisotropic permeability space is transformed into isotropic permeability space, and prediction is made about the productivity of herringbone multi-lateral wells with percolation model. It can be conclude that: Reservoir anisotropy can change the pressure distribution dramatically. The greater anisotropy is, the more obvious deflexion there is; The permeability which is perpendicular to the main bore of herringbone multi-lateral well plays the most important role on the productivity. The permeability which parallel to the main bore of herringbone multi-lateral well plays a secondary role on the productivity. When the anisotropy is clear, the direction of the main bore of herringbone multi-lateral well should be perpendicular to the direction of the main permeability. When the anisotropy is unknown, a big branch angle should be picked to eliminate the influences of anisotropy.关键词
