自然伽玛测井是目前测井系列中不可缺少的方法之一。它对砂岩、页岩、粘土、泥岩、石膏等等,都有较好的反映。对找钾也有很好的效果。在三叠系地层找钾能进行单解。国外有不少钾矿床就是用自然伽玛测井资料发现的。在实际测量中,由于仪器稳定性差、统计起伏过大或过小,使得到的资料无法进行解释,给工作造成损失。为此,我队规定在测量自然伽玛曲线的开始和结束时,在预先 Natural gamma logging is one of the indispensable methods in current logging series. It is a good reflection of sandstone, shale, clay, mudstone, gypsum and so on. To find good effect of potassium. Looking for potassium in the Triassic strata can be single solution. Many foreign potassium deposits are discovered using gamma ray logging data. In the actual measurement, due to poor stability of the instrument, statistical fluctuations are too large or too small, so that the information can not be explained, to work losses. For this reason, my team prescribes that at the beginning and at the end of the measurement of the natural gamma curve
