摘要
应用模糊数学理论和层次分析方法，建立了小井眼钻井技术经济评价的新模型，并应用于实际钻井中。针对钻井经济评价的复杂性，该模型对小井眼钻井的１１个指标进行综合分析，应用模糊数学方法将多个指标值转化为隶属度，应用层次分析方法将多个指标逐步合并，使各方案可直接进行比较，提高了评价的可靠性，为钻井工作人员提供了定量化依据；将该模型应用于大庆油田小井眼钻井实际。
Fuzzy mathematics and
AHP(analytical hierarchic process)are applied to establish a new technical and economical
evaluation model of slimhole drilling,and the model is used in drilling practice.In the
model,eleven indexes of slimhoe drilling are comprehensively analyzed,several indexes are
changed into membership degrees by fuzzy mathematics.Several indexes are combined step
by step,based on AHP.Thus,the complexity of drilling economic evaluation is extricated.As a
result,a technical and economic analysis would be made quantitatively by drilling people.
