γ测井资料反褶积分层解释法在8411矿床的试验对比

γ测井资料的反褶积分层解释法具有方法简单,精度高,速度快,分辨能力强,用微机进行计算等优点。作者通过用反褶积法对8411矿床γ测井资料的解释,对视特征参数的选择条件,γ强度底数的确定和划分矿层边界的原则,提出了初步看法。将该法的试验结果与传统的平均含量法和矿心分析结果进行了对比,还分析了视特征参数的取值大小对矿层线储量及矿化分层的影响,并讨论了引起线储量相对误差的原因。

THE TEST EFFECT OF DECONVOLUTION TECHNIQUE ON INTERPRETING THE GAMMARAY LOGGING DATA IN THE NO 8411 DEPOSIT

The technique of deconvolution to interpret the gamma-ray logging data has the advantages of simplicity, accuracy, fastness, and high resolution. In this paper, the author puts forwards several preliminary ideas of selecting the conditions of the apparent geological response parameter(?),determining the intensity of gamma-ray background, and delineating the limits of the ore zones, by the use of deconvolution technique to interpret the logging data in the No. 8411 deposit. The analyses have been undertaken in order to determine the effects of the value of the apparent response parameter on linear reserves within the ore zones and the subdivision of the mineralized zones. In order to test this technique, the results obtained by deconvolution technique have been compared with that of the traditional average content method and ore core analysis. Finally, the reason causing the relative error of linear reseaves is discussed.
