水力压裂裂缝三维延伸数值模拟研究

STUDY ON NUMERICAL SIMULATION FOR 3-DIMENSIONAL FRACTURE PROPAGA-TION IN HYDRAULIC FRACTURING

    摘要
  • 摘要: 在分析国内外已有裂缝三维延伸模型的基础上,建立了一套新的水力压裂裂缝三维延伸模型,模型的主要发展是考虑了产层、盖层和底层之间的应力和岩石力学参数(弹性模量、泊松比、断裂韧性)变化的影响,能模拟各种应力分布模式以及裂缝穿层前后的延伸情况。以该模型为基础研制了一套三维压裂优化设计软件并进行了大量的实例计算。

     

    Abstract: Based on the analysis on the 3-dimensional propagation model at home and abroad, we have worked out a new 3-dimensional fracture model, which considers the effects of mechanical parameters of the payzone, the cover and the bottom. It can simulate the stress distribution mode and fracture propagation before and after fracturing. We have also worked out a computer software and made many calculation for field examples based on the said model.
