摘要
在进行煤田测井时,由于钻孔井径、丼液性质差别,导致自然电位曲线、三侧向电阻率曲线不能很好地反映地层的变化,本文结合陕北某煤田测井实际,分析了井液、井径对自然电位曲线、三侧向电阻率测井曲线影响的原因。
The differentiation of well diameter and well fluid used in coalfield well logging would re- suit in the natural potential curve and the three lateral resistivity curve obtained unable to reflect the changes of strata properly. According to practical coalfield well logging in northern Shaanx/, this pa- per discussed the affected reason of well diameter and well fluid on the natural potential curve and the three lateral resistivity curve
