Abstract: Based on the needs of oilfield development,this paper presents the thinking of parameters optimum for limited entry fracturing,establishs a pseudo-three-dimensional limited entry fracturing model.Combining with the advantages of two-dimensional fracturing model,which are high calculating speed,simple and convenient,and that of three-dimensional fracturing model,which may truely reflect the extension of fracture height,the new model realizes the parameters optimum design of limited entry fracturing,and saves plenty of calculating time.
