摘　　要：C油田为典型的强底水油藏,采用单砂体水平井开发。由于底水能力强,导致油井含水上升快,油藏面临的最大问题就是底水锥进,如何通过生产动态识别水平井见水位置对指导生产工作具有实际意义。提出了一种新的见水模式评价指标体系以及相应的评价方法,借助MATLAB编程根据底水油藏水平井生产动态辅助识别见水模式,并通过数值模拟软件对不同条件下见水模式评价方法的适用性进行了分析与验证,对底水油藏控水稳油有一定指导意义。C Oilfield is a typical reservoir with strong bottom water,which is developed by horizontal well with single sand.Due to the strong bottom water capacity and the rapid rise of water cut,the biggest problem faced by oil reservoirs is the coning of bottom water.How to identify the water reach location of horizontal wells through production dynamics has practical significance for guiding production work.A new evaluation index system of water emergence mode and corresponding evaluation method are proposed.The production dynamics of horizontal wells in bottom water reservoirs is evaluated and water emergence mode is identified by MATLAB programming.The applicability of the evaluation method of water emergence mode under different conditions is analyzed and verified by numerical simulation software,which has certain guiding significance for controlling water and stabilizing oil in bottom water reservoir.
