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 of the well are done to provide the guidance for implementation of the field horizontal well’s fracturing .
