利用水平井开采边水油藏，水侵是一个不可避免的问题。油井见水后会造成单井产能迅速下降和单井控制储量急剧减少，严重影响油藏的最终开发效果。以数值模拟技术为主要研究手段，通过建立理想机理模型，对油藏的含水上升规律进行了模拟研究，并对影响含水上升规律的各种因素进行了定量化分析。研究结果对于制定合理的边水油藏开发技术对策，降低水侵对开发效果的影响，提高该类油藏的最终采收率意义重大。
利用水平井開採邊水油藏，水侵是一箇不可避免的問題。油井見水後會造成單井產能迅速下降和單井控製儲量急劇減少，嚴重影響油藏的最終開髮效果。以數值模擬技術為主要研究手段，通過建立理想機理模型，對油藏的含水上升規律進行瞭模擬研究，併對影響含水上升規律的各種因素進行瞭定量化分析。研究結果對于製定閤理的邊水油藏開髮技術對策，降低水侵對開髮效果的影響，提高該類油藏的最終採收率意義重大。

In edge water reservoir recovered by horizontal wells, water invasion is inevitable. After water breakthrough, single well production decline rapidly and single well controlled reserves reduce sharply, which will seriously affect the final development ef-fect of reservoir. Taking numerical simulation technology as the main research measure and by establishing ideal mechanism mod-els, water cut rising rules were studied and various affecting factors were quantitatively analyzed. The research results have great significance to formulate reasonable edge water reservoir development scheme, reduce the influence of water invasion on develop-ment effect and improve the ultimate recovery of reservoirs.
