摘要: 提出一种用声波测井资料和水力压裂数据来计算水平地应力值的新方法,并将它应用于新疆吐哈油田,计算得出的水平主地应力值与由凯塞效应测得的进行了对比,两者一致性好,而且用声波法求得的水平主地应力值来预测破裂压力与实测的地层破裂压力相比误差小.现场应用表明,声波法计算水平主地应力值具有很好的实用价值.

Abstract: A new method to calculate the values of horizontal principal in-situ stress with acoustic logging curves and the data of hydraulic fracturing is developed,which is applied in Tuha oilfield of Xinjiang.Values of the horizontal principal in-situ stress by the new method are consistent with the values by Kaise effect method,moreover,with which formation fracture pressures are predicted.The relative errors are little between the theoretic and practical formation fracture pressures.The all what have been done prove that the new method is of important value.

Key words: in-situ stress, acoustic logging, hydraulic fracture, fracture pressure
