摘要
地层倾角测井资料具有多个（≥2个）井径测量信息，具有判定井眼几何形状的能力，可以用以确定地层主应力方向。目前海拉尔盆地乌尔逊油田的地应力方向是利用XMAC测井资料确定的，为充分利用该地区的测井资料得到尽可能准确的地应力信息，应用该区的地层倾角测井资料，采用钻孔崩落法研究确定了该区的地层主应力方向。并与XMAC测井资料确定的地层主应力方向进行对比，具有较好的一致性。
Diplog data have several(≥2) caliper data which can be used to judge borehole geometry and determine the direction of principal stress.At present the stress direction of Wuerxun oilfield is determined by XMAC well logging data.In order to get more accurate ground stress information and make full use of diplog data of this area,wellbore breakouts is used to determine the formation principal stress direction.It is consistent with that determined by XMAC well logging data in comparison.
