| 摘 要： | 本文以冀东油田磁偏角现场实测数据结合采油井的钻探效果进行探讨，事实表明，由于受到构造运动、风化沉积和岩浆侵入等因素的共同作用，地下浅层构造比深部存在更多的横向不均匀，导致局部小范围磁偏角较大波动，它对油田定向斜井钻探将带来一定影响。

| Abstract: | In this paper it investigated that magnetic declination datum on Jidong oil field compare with practical effect of oil well exploration. Results show that shallow structure is horizontally more inhomogeneous than deep structure because structure motion, weathering, deposit and magmatic intrusion in Earth's crust induce a big magnetic declination change in very small area. This will influence orientable well's precision of hit the target. |
