从油田开发整体要求的角度出发,提出了优化限流压裂施工参数的思路,建立了适用于限流压裂裂缝延伸的拟三维数学模型,并综合了裂缝延伸模拟二维模型计算速度快、简便省时和三维模型较真实反映缝高延伸的优点,从理论上实现了限流压裂施工参数的优化设计,共节省了大量的设计计算时间。

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.
