摘要:

为了使压裂设计更符合实际情况,近年来倾向于使用裂缝三维延伸的数学模型。本文以I D Palmer缝高模型为基础,应用线弹性断裂理论,建立了适合层状分布油气层压裂时裂缝拟三维延伸动态尺寸计算的数学模型,模拟了裂缝三维延伸过程中裂缝尺寸随时间的变化关系。

Abstract: Pseudo-three-dihiensioital macliematical model has Cended to be used for fitting the design of fracturing to the actual situation more in the past few years, Based on I.D, Palmer,s”fracture height”model and linear elastic fracture mechanism, the mathematical model is established,which is suitable for fracturing in layers. The function of fracture size and time in the process of fracture extension is given in this paper,

Key words: Hydraulic fracturing, Fractured fracture, Fracture extension, Three dimensioal model, Mathematical model, Numerical simulatyon
