生产动态和油藏静态结合研究剩余油分布的理论与方法
|
摘要
剩余油的分布受控于油藏静态与生产动态,动、静结合研究剩余油的方法就是从动、静两个方面进行研究,并建立评价体系,从而综合评价油藏的剩余油分布状况。静态的研究着重于沉积微相及储层非均质性的研究;而动态的研究着重于研究水淹情况的变化,并分析来水突进的方向;结合的办法采用灰色关联法。利用12个动、静态评价因子,通过对西江30-2油田边、底水油藏建立评价体系,采用这种评价方法,可以发现其评价效果较好。在综合评价过程中,主控因素可能并不仅仅为一个,应根据不同油藏采用合理方法选取恰当的主控因素,以达到有效评价剩余油的分布。
The remaining oil distribution was controlled by the reservoir's static geology condition and the dynamic production status. The remaining oil distribution method of dynamic and static combination research is such a process related to two aspects respectively;and an evaluation system is constructed to study the remaining oil distribution status comprehensively.The static research emphasizes on reservoir's sedimentary micro-facies and heterogenity;meanwhile,the dynamic research pays more attention to the changing of the water out status and the analysis of water cusping direction.The method of Grey Association Analysis is adopted to research the remaining oil distribution.Using 12 dynamic and static evaluation factors,constructing some valuation systems on edge water or basal water reservoirs,adopting this method to study the remaining oil distribution,the method is feasible.In the comprehensive evaluation,there are more than one major factor.Therefore,several major factors should be selected correctly according to different reservoirs in order to realize the aim of effective evaluation of the remaining oil distribution.
