摘要： 水平井压裂技术是开发难动用低渗储层的有效手段, 为更好指导水平井现场压裂优化设计和施工,建立考虑导流能力变化的水平井压裂三维两相生产动态模型, 并用经典方法验证其准确性, 并以此为基础编制水平井压裂参数优化设计模拟软件, 综合考虑各方面因素, 采用单因素分析和多因素分析相结合的方法对影响因素进行
敏感性分析, 并选取对水平井压裂影响较大的5个因素, 采用正交试验结合灰色关联分析方法优选多因素影响条件下裂缝参数, 分析表明裂缝半长和条数是影响压裂水平井的最主要因素。根据试验结果对现场一口井进行方案优选, 为现场水平井压裂的实施提供重要的指导意义。

Abstract: Horizontal well fracturing technology is an effective mean of developing the low,ultralow permeability reservoirs. For guiding the optimal design and construction of the fracturing of horizontal wells in field, establish the threedimensional twophase producing dynamic models considering changes in the conductivity of horizontal well fracturing was established,and the dynamic simulation of horizontal well fracturing production software was prepared to analysis the sensitivity of fracture geometry parameters, reservoir conditions, production of construction time and etc. And the influence degree of all kinds of factors were considered throught single factor and multifactor analysis.Based on the result of single factor anlysis,five factors that impact larger were selected out for the multifacor analysis.Orthogonal experiments and grey correlation analysis were used for the mulitfactor analysis.The result shows that the fracture number and length are the main two factors. According to the analysis result,the optimization [ＫＧ*４]of [ＫＧ*４]the [ＫＧ*４]well [ＫＧ*４]are [ＫＧ*４]done [ＫＧ*４]to [ＫＧ*４]provide [ＫＧ*４]the guidance for implementation of the field horizontal well’s fracturing.

Key words: Horizontal well fracturing,    ,  Fracture geometry parameters,    ,  Optimal design,    ,  Orthogonal test,    , Grey correlation analysis
