藻灰岩储层在测井曲线上显示出较高的自然伽马值，在地震剖面上表现为强反射特征。
Algal limestone reservoirs appear to have relatively high gamma ray value in well logs and strong reflectance signatures in seismic profiles.
这种高产气层具有特征的电性反应，表现为自然伽马值低、自然电位显著负异常、电阻率高；
The log response of the gas reservoir is characterised by low gamma ray, self-potential reduction and high resistivity.
在砂泥岩剖面中，泥岩往往比砂岩具有较高的自然伽马值，从而可以利用自然伽马测井将砂岩储层划分出来。
Based on the features of mudstone with higher gamma ray than sandstone in sandstone -mudstone section, we can distinguish sandstone reservoir from the drilling profiles with gamma ray log.
尽管裂缝—孔洞系统与洞穴地质结构有较大差异，但测井响应一般均表现为：伽马值较低，大缝、洞穴中填充泥质时值较高；
The log response, the cracks-holes systems and caves response vary, but generally as follows: The GR is relatively low, but it is higher when the joints or the cave filled with mud;
