| 摘 要： | 完井方式的选择受多种因素的制约，如产量、净现值、完井成本、完井产能、边底水锥进、储层岩石坚 固程度等，各因素间存在着不确定性、随机性以及模糊性。通过采用相对偏差模糊矩阵、模糊层次分析法 及非线性模糊矩阵合成算子，改进了模糊综合评价模型。其模型综合了各种因素，并权衡技术、经济等指 标，对完井方式进行了综合评价，分析求取了最优完井方式的隶属度。改进后的模型评价其结果与实际更 为相符，验证了该模型的可行性及可靠性，具有评价优势。

| Abstract: | The uncertainties,randomness and fuzziness exist in many factors such as output,net present value,completion cost,deliverability,edge and bottom water coning and the degree of the reservoir rock soundness and so on,which all influence the selection of well completion.By adopting relative deviation fuzzy matrix,fuzzy analytic hierarchy process and fuzzy matrix synthesis operator,this paper improved fuzzy comprehensive evaluation model.In this model,we generalized the influencing factors,weighed the technology index and economy index,comprehensively evaluated the well completion system,and worked out the optimal membership degree.The improved model evaluation result agreed more with the reality,which proves the feasibility,superiority and reliability of this improved fuzzy comprehensive evaluation model. |
