用层次分析法优选喇萨杏油田三次加密调整区块

An Application of the Hierarchical Analysis Progress Method in the Tertiary Infilling Optimum Blocks of the La-Sa-Xing Oilfield

以检查井分析资料和二次加密调整井测试资料为基础,以大庆喇萨杏油田已开展的三次加密调整试验和已完成的三次加密调整方案为依据,通过对喇萨杏油田高含水后期各开发区块可调砂岩厚度、单储系数、综合含水、二次加密调整时间及套损井比例等几个主要指标综合分析的基础上,利用层次分析方法对喇萨杏油田各开发区块三次加密调整的可行性进行优选排队,最终给出喇萨杏油田三次加密调整优先进行的区块,为喇萨各油田有计划、分步骤地实施三次加密调整提供了可靠依据。

Based on the comprehensive analyses of adjustable thickness, geologic characters, combined water cut, secondary infilling time and casing damage condition in different blocks in La-Sa-Xing oilfield, using inspection well and secondary infilling production behavior data, this paper makes a optimum ordering of tertiary infilling blocks in La-Sa-Xing oilfield by using the hierarchical analysis progress method. This method provides a theoretical basis for implementing tertiary infilling and adjustment step by step in a planned way in La-Sa-Xing oilfield.
