针对于低孔、低渗储层,通过实验室评价岩心实验分析成果,常规测井和核磁共振测井资料并用,提出DMR孔隙度测井解释模型,并采用致密含气砂岩储层的测井解释评价方法,对研究区典型的致密砂岩储层进行测井解释分析。研究成果表明,密度测井与核磁共振测井方法相结合来计算孔隙度解释的效果更好。并讨论了这些方法对致密含气砂岩储层参数计算的精度,研究的解释方法理论上可行,在实际应用中效果较好,能够满足实际需求。 Aimed at low porosity and low permeability reservoirs, DMR porosity logging interpretation models are proposed by laboratory evaluation of core experimental results, conventional logging and NMR logging data, and logging with tight gas-bearing sandstone reservoirs Explain the evaluation methods, and log interpretation analysis of the typical tight sandstone reservoirs in the study area. The research results show that the combination of density logging and nuclear magnetic resonance logging to calculate porosity is better. The accuracy of these methods in calculating gas reservoir parameters of gas-tight sandstone is discussed. The method of interpretation is theoretically feasible and effective in practical application, which can meet the actual needs.
