层次分析方法在喇北东块储层评价中的应用

目前证实喇北东块外扩区萨一组具有一定的地质储量和外扩布井的潜力。为了在下一步的开发工作中能够更好地优选出布井有利区及射孔层位,此次研究利用层次分析理论对外扩区萨一组储层进行综合分类评价,将影响储层的多个因素转化成一个综合评价指标上。最终优选出L 125-1、L 125-2及L 55-2井区的萨一组3、4+5号小层及L 55-1井区的萨一组1、2号小层,其储层性质较好,是布井的有利区及射孔层位。经试油论证该方法具有一定的可靠性,寻找出了适合本油田储层发育状况的综合分类评价方法,对开发布井及射孔层位方案编制具有一定的参考指导性意义。

Used The Analytical Hierarchy Process To Apply In The reservoir Evaluation Of The Northeast Out Stepping Block In La Madian Oil Field

At present it has been approved that the first Sa Ertu oil layer of the north east out stepping block of La Madian oil field has the considerable geologic reserve and the latent capacity of the placing of well.For the sake of the further development,and optimizing the placing of well’s range of profitability and perforated interval.This research used the analytical hierarchy process to evaluate comprehensively the first Sa Ertu oil layer’s reservoir of out stepping block,converted many affecting factors of the reservoir to one comprehensive evaluation target.At last we optimized out the No.3,No.4,and No.5 member of the first Sa Ertu oil layer in L125-1、L125-2 and L55-2 well field,and the No.1 and No.2 of the first Sa Ertu oil layer in L55-1 well field.These members are preferable reservoir,are range of profitability of well arrays and perforated interval.this method is demonstrated that has definite dependability by testing for oil,and find out one synthetic taxonomy rating method which is fit for vegetal state of reservoirs.This method has a bound reference and directive intention for drawing up development plan and concept of perforated interval.
