摘　　要：在测井曲线中,自然电位测井曲线(SP曲线)和自然伽马测井曲线(GR曲线)在砂泥岩处测井响应特征明显。在应用中,通常认为自然电位曲线向左偏移(负方向)为砂岩,自然伽马测井曲线向左偏移(负方向)也为砂岩。The logging response characteristics of spontaneous potential curve(SP curve)and gamma ray logging curve(GRcurve)in the sandstone and mudstone is obvious.It is usually considered that natural potential curve shifts to the left(negativedirection)for sandstone,natural gamma logging curve shifts to the left(negative direction)for sandstone.
