摘要
灰色关联法进行剩余油分布研究是一种综合各种动、静态参数(如微相、生产井影响因子等)的多参数综合评价方法,而采用改进的多主因子逐级权系数确定方法更易于针对不同油藏特点进行剩余油分布评价。这一方法应分三步进行:地质静态研究、生产动态分析、灰色关联综合评分。采用灰色关联法对西江30-2油田HB油藏进行剩余油分布评价,与实际生产吻合较好。
Abstract
Grey association analysis is a useful method with multiple parameters, i.e. through integrating many dynamic and static parameters,such as micro-facies,production well affecting factor, and etc, to predict remaining oil distribution.Moreover, through the modifying weight coefficient's calculating method with multiple major factors, it is much easier to evaluate remaining oil distribution according to different reservoirs' characteristics. This method can be divided into three steps: first, static geology study; second, dynamic production analysis; and third, synthesis valuation with grey association analysis. With grey association analysis, it is available to evaluate remaining oil distribution on HB reservoir in Xijiang 30-2 oilfield and is consistent with the actual production data.
