Abstract
The pressure index(PI) decision-making technique is a decision-making technique by the parameter PItGt value for determining the major issues of injectors profile control on the block wide. PItG value can be obtained first by the PIt value calculated based on the pressure drop curve at the wellhead of injector and the definition formula of PIt value, and then by the PIt value correction based on the round average of the injection strength of injectors on the block wide. PItG value can be used for determining the necessity of profile control on block wide, determining the wells for profile control, selecting the agents used in profile control,calculating the amount of the profile control agents, evaluating the effects and deciding the repeated construction time. In recent years, the applications of PIt value and PItG value have made some progresses respectively in distinguishing the full degree of profile control, judging the dominant permeable pathway, selecting the water shutoff wells and guiding profile control construction.关键词
