| 摘 要： | 根据安棚油田低孔、低渗的地质特征,选择Newberry模型和双井径模型计算地应力。提出了用成像测井提供的3条井径和6条极板半径曲线确定椭圆井眼长、短轴的方法,解决了在没有四臂地层倾角测井资料的情况下无法用双井径模型计算地应力的问题。所提出方法在安棚油田地应力研究中取得了良好的效果。

| Abstract: | Based on the low-porosity and low-permeability in Anpeng oilfield,Newberry model and a dual caliper model are selected to calculate earth stress in reservoirs.A method to determine long and short axes of elliptical wellbore by using 3 capiper curves and 6 plate radius curves from imaging logging has been developed,by which the problem that dual caliper model can not calculate earth stress without 4-arm dipmeter log data is resolved.An application of this method to the earth stress study in Anpeng field has made good results. |
