| 摘 要： | 在分析国内外裂缝三维延伸模型的基础上，全面考虑压裂液缝高压降、液体重力、地应力梯度、地应力差等因素对裂缝延伸的综合影响，建立一套新的裂缝三维延伸数学模型，并给出相应数值求解方法。由于考虑了压裂液缝高方向流动，建立的模型对缝高预测更符合实际，对于指导压裂设计特别是控制缝高压裂有一定的实用意义。

| Abstract: | On the basis of analysis of internal and external 3D models of fracture propagation, studying overall effect of all kinds of factors on fracture propagation such as vertical pressure drop of fracturing liquid, fluid gravity, ground stress gradient and stress difference,a set of new mathematical model and numerical solution method are developed. Because of considering fracturing fluid flow in the vertical direction, the model is more reasonable for fracture height prediction. |
