| 摘 要： | 为了更好地采用水平井开发地层原油, 该文分析了水平井对底水油藏的不适应性, 认为水平井对水锥的抑制效果有限, 其极限采收率低于直井, 并且增产措施难以实施, 裂缝会加快水锥。因此, 水平井并不适合底水油藏的开发, 它适合于薄层、低渗和稠油等直井产能较低的边水油藏。

| Abstract: | The adaptability of horizontal wells for bottom water reservoirs is analyzed in order to develop reservoir more efficiently. The result shows that the effect of horizontal well on curb water coning is limited , the limit recovery efficiency of it is lower than that of vertical well , and the stimulation treatments for it are difficult to be carried out . It concludes that horizontal wells are not suitable for bottom water reservoir development , but advantageous for edge water reservoirs with thin layer , low permeability and heavy oil . |
