层次分析法在临兴区块集输管道积液解决方案优选中的应用

Application of AHP in solution optimization of gathering pipeline effusion in Linxing block

为促进临兴区块致密气资源勘探开发,加快产能发挥,依据目前临兴区块地面集输现状,提出3个集输管道积液解决方案。运用多目标决策分析的原理,基于层次分析法,构建方案优选模型,通过算术平均法得到评价指标权重,建立判断矩阵,计算综合评价指标并排序,将具有主观性的指标用数值形式表达并进行量化综合比较,克服了传统方案优选(采用优缺点对比方式)的不足。经过计算方案层权重因子,最终推荐在E井场设置分水阀组的方案。在保证安全运行的前提下,该方案使得临兴区块集输管道积液问题得到最大程度解决。

In order to promote the exploration and development of tight gas resources in Linxing block and give full play to the production capacity,three solutions of gathering and transportation pipeline effusion are proposed according to the current situation of surface gathering and transportation pipeline network in Linxing block.Using the principle of multi-objective decision analysis and based on the AHP method,this paper constructs a scheme optimization model,obtains the evaluation index weights through the arithmetic average method,establishes the judgment matrix,calculates and sorts the comprehensive evaluation indexes,expresses the subjective indexes in quantitative form and makes quantitative comprehensive comparison,which overcomes the shortcomings of the traditional scheme optimization method(i.e.comparing advantages and disadvantages).After calculating the weight factor of scheme layer,the scheme of setting dehydration valve group in wellsite E is recommended.Below safe premise,the problem of gathering pipeline effusion in Linxing block is solved to the greatest extent.
