摘　　要：论述了现今构造应力场数值模拟及裂缝有效性预测的原理及实现方法。用其对马东东地区主要目的层沙一段下亚段进行裂缝分析 ,明确了裂缝走向 ,确定了北东东、北西两大裂缝体系。在此基础上 ,对裂缝的有效性进行了预测。Numerical simulation of recent structural stress field, prediction principle of fracture effectiveness and performing method are discussed. The fractures of main target zoneEs1 in Madongdong area are analyzed. The fracture strike is difinited. Northeasteast and Northwest two fracture systems are determined. Accordingly, fracture effectiveness is predicted. Its feasibility is proved by practice.
