摘　　要：随着青海油田的勘探目标转向复杂岩性、隐蔽型油气藏,越来越多的储层需要压裂后才能获得工业油流。迫切的需要一套有效的方法来评价指导压裂作业。偶极声波测井能够测得地层的纵横波时差,利用纵横波时差可以计算地层的弹性模量、固有强度和地应力,进而不仅可以预测地层的破裂压力和压裂缝高度,还可以预测泥浆密度的安全范围。通过实例分析证明,这几种工程应用在本区块都有较好的效果。With the exploration target of Qinghai oilfield turning to the complex lithology and hidden reservoirs,concealed reservoir,more and more reservoirs need fracturing to get industrial oil flow.There is urgent need for an effective way to evaluate and guide fracturing operations.Dipole acoustic logging can measure the vertical and horizontal wave time difference of the formation which is used to calculate elasticity modulus,inherent strength and ground stress,and then to predict fracture pressure and pressurebreak height and also safety limit of mud density.Case analysis proves that the applications have preferable effect.
