摘要
RDM (Reservoir Data Miner)是最新研制的针对低孔低渗地层的脉冲中子饱和度测井仪。实际测井中套后自然伽马由于受水淹影响发生变形,与裸眼井自然伽马校深困难,提出了替代套后自然伽马的校深索引曲线。通过对套后自然伽马曲线归一化分析,提出了一种水淹层指示方法。
RDM is a new pulsed neutron saturation logging tool for low porosity and low permeability formation. Depth correction is difficult due to the water flooding deformation in the actual logging. In this paper, an alternative method is proposed. And based on the normalization analysis of the natural gamma curve, a water flooded layer indicator method is proposed.
