摘　　要：油田注水开发系统为一耗散结构系统,遵从耗散结构的规律。基于灰关联熵,利用支配主宰系统发展演化的序参量,可对系统发展演化进行分析研究。负熵流是耗散结构非平衡有序结构形成的必要条件,处于负熵流状态的系统,表明系统总熵不断减小,系统能量利用效能较好,有序度增强,各要素子系统间协同匹配较好,系统处于良性发展演化过程之中。必须针对地下油藏不断变化的油水运动规律,不断调整开发技术对策,才能使油田注水开发系统走向比较协调健康的负熵开采道路。The oil field waterflooding system is a dissipative system and follows the law of dissipative structure. Based on the grey correlation entropy, the system development and evolvement can be analyzed and studied by the use of the dominate factors that control the system evolvement direction. The minus entropy flow is the prerequisite for unbalanced and orderly structure of dissipative structure. Under the circumstances of minus entropy flow system, the system is in course of benign development and evolvement with decreasing gradually overall entropy and good efficiency of system energy in use, and in good order tendency and with good cooperation and matching among elemental subsystems. The development technical policy must be continually readjusted in accordance with constantly diverse oil water motion law so that minus entropy can be introduced to harmoniously exploit the oil field.
