摘要
水力压裂是油气藏改造中最常用的工程措施 ,通过数值模拟研究水力压裂过程具有十分重要的意义。将Gurson损伤模型引入水力压裂分析中 ,建立水力压裂的损伤力学模型。通过数值计算分析水力压裂对多孔介质的损伤效果 。
Hydraulic fracturing is a common engineering measure used in oil reservoir remolding, and numerical simulation of the process is of significant to oil recovery. A continuum damage model of hydraulic fracturing was developed by introduced Gurson damage theory. Through a simple calculation case, damage zone of a hydraulic fracturing well with a perforation was simulated. In the end, basic research method of hydraulic fracturing using damage mechanics theory.
