Abstract: 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.

Key words: reservoir performance, reservoir assessment, dissipative structure, entropy, minus entropy
