应用弹性位移理论进行裂缝预测

Fracture Prediction by Elastic Dislocation Theory

论述了应用弹性位移理论进行裂缝预测的建模方法,并将弹性位移理论建模应用于预测北海Gullfaks油田断裂块内的裂缝发育方向、模式及密度。详细的断裂构造解释是框架模型建立和进行准确裂缝预测的基础。裂缝预测结果受地质模型、几何框架模型、岩石的力学性质和区域背景应力的影响。

The modeling method of fracture prediction by using elastic dislocation theory has been discussed, and application of elastic dislocation theory to predict the fracture development orientation, mode and density of faulted blocks in Gullfaks oilfield in North Sea was conducted. The detailed fault structure interpretation is the base to build the framework and predict the exact fracture. The results of fracture prediction would be affected by geologic model, geometric framework model, rock mechanics properties and regional stress background.
