摘要
本文讨论了最佳测井点距的选择原理,其最佳值大致为8—12.5cm.并从原理上分析了矿层解释厚度增大的主要原因:根据离散测量值所作的分层解释结果必然导致矿层解释厚度的增大.大量的模型测量结果完全证实了理论分析的正确性,并且还提出了合适的解决办法.
This paper describes the principles of choosing the optimal sampling interval of γ-logging, its optimal value is about 8-12.5 cm. This paper also analyses the basic cause of the excess of the evaluated thickness of uranium strata; orignating from discrete values of y-logging data, the evaluated values of the thickness of uranium strata by means of differential interpretation method frequently lead to the excess of the thickness of uranium strata. A lot of model experimental results have confirmed the validity of theoretical discussion and finally, we also offer the appropriate method of improving the accuracy of the evaluated thickness of uranium strata.
