摘　　要：以延长油田七里村基础数据为依据,利用测井、压裂资料计算储层三向地应力剖面,以储层水力压裂时产生垂直裂缝和水平裂缝的破裂压力相等为临界深度,计算临界裂缝深度。通过实例验证该方法的准确性。Based on Yanchang Oilfield Seven Village basis data,the three Gravitropism stress profile could be calculated by the logging and reservoir fracturing data; and the critical crack depth could be calculated when the reservoir hydraulic fracturing and horizontal cracks in vertical fracture pressure is equal to the critical depth. Application examples show that the method is easy to use,and has fast calculation speed and high accuracy.
