摘要/Abstract

摘要： 假设油藏为矩形油藏，且封闭水体线性分布于油藏一侧，分别推导和建立了关于裂缝型碳酸盐岩油藏、缝洞型碳酸盐岩油藏的非稳态线性水侵模型。采用现代数学方法对模型进行求解，并编程绘制碳酸盐岩边水油藏的线性水侵曲线，对两类碳酸盐岩边水油藏的水侵曲线进行了对比分析以及绘制了无限大水体时的水侵曲线。此外，通过绘制不同参数下的缝洞型碳酸盐岩油藏水侵曲线，对该类油藏的水侵特征及水侵规律进行了分析。最后，结合塔里木盆地缝洞型碳酸盐岩边水油藏现场数据对水侵模型进行了实例应用分析。研究结果表明： 1）裂缝型碳酸盐岩油藏水侵曲线后期出现一个上升阶段，缝洞型碳酸盐岩油藏水侵曲线后期出现两个上升阶段； 2）窜流系数影响水侵曲线上升阶段出现的早晚； 3）储集系数影响水侵曲线相应阶段位置的高低； 4）水体距离影响水侵曲线后期所有阶段的位置高低；5）充分认识碳酸盐岩油藏边水水侵特征和水侵规律是合理高效开发碳酸盐岩油藏的重要保障。

Abstract: The unsteady linear water invasion models of fractured carbonate reservoir and fracture-vuggy carbonate reservoir were deduced and established respectively, assuming the reservoir was rectangular and the closed water body was linearly distributed on one side of the reservoir. Then the models were solved by modern mathematical methods, and the linear water invasion curves of carbonate edge-water reservoir were plotted. The water invasion curves of two kinds of carbonate edge-water reservoirs were compared and analyzed, and the water invasion curves of infinite water body were also drawn. In addition, the characteristics and rules of water invasion were analyzed by drawing water invasion curves of fracture-vuggy carbonate reservoirs under different parameters. Finally, the water invasion model was applied and analyzed combined with the field data of fracture-vuggy carbonate edge-water reservoir from Tarim Basin. The results show that: 1) There is one ascending stage in the late stage of water invasion curve for fracture carbonate reservoir, and two ascending stages in the late stage of water invasion curve for fracture-vuggy carbonate reservoir. 2) The interporosiy flow coefficient affects the occurrence of the ascending stage of water invasion curve. 3) Storage coefficient affects the position of the corresponding stage of water invasion curve. 4) Water distance affects the position of all stages in the late stage of water invasion curve. 5) It is an important guarantee for the rational and efficient development of carbonate reservoir to fully understand the characteristics and rules of water invasion.

Key words: rectangular reservoirs, carbonate edge-water reservoirs, linear water invasion model, water invasion curve, water invasion characteristics
