| 摘 要： | 对塔北油田不同钻孔的不同深度的岩心进行现今地应力最大主应力值测量，救是了测区现今最大主应力随深度变化规律，得出了如下重要的认识；在测区的相同深度上，出油井比出油井最大主应力偏低，油井的出油岩层与非出油层相比，前者的最大主应力偏低。

| Abstract: | The magnitude of present maximum principal stress of Northern Tarim oil field is determined by means of AE and the relationship between the magnitude and the depth is given, a conclusion can be made that the magnitudes of maximum principal stress of oil well producing are lower than those of non oil wells at the same depth in the Northern Tarim oil field. A similar situation between pay beds and non pay beds in the wells producing oil is shown. It seems that the above conclusion can be used as a criterion in determining oil producer. |
