摘　　要：根据有效压力原理,通过实验和加压方式的变化,模拟在不同开发方式下,地层压力下降不同时对储层伤害的影响。通过岩心在不同受力情况下的变形特征及渗流特性分析认为:对异常高压油藏,可以通过改变初期油井工作制度(如开关井、控制采油速度、减小快速开采)引起的压力快速下降,减小对储层的伤害,进而减小对油井产能的影响。文中研究结果为此类油藏科学合理的开发提供了理论依据。According to the effective pressure theory, the influence of different pressure drop on reservoir damage under different development methods is simulated by experiment and pressing mode. By analyzing the deformation and seepage characteristics of core under different effective pressure, it is considered that for the abnormal high pressure reservoir, by changing the work system for initial oil well, such as opening-shutting well, controlling the oil production rate and reducing the rapid extraction, the reservoir damage caused by fast pressure drop and the influence of oil well productivity can be reduced. Study results can provide theoretical basis for the scientific and reasonable development of such reservoir.
