摘    要:可可西里雅西措组发育多层石盐层。为有效识别石盐矿深度、厚度,预测其工业品位,提出基于归一化后的自然伽马和密度曲线重构石盐指示曲线,用以划分石盐与砂泥岩,该方法与测井交会图法、测井曲线重叠法相比精度高。利用石盐指示曲线与石盐样品测试结果建立预测石盐矿工业品位相关关系,与自然伽马法、孔隙度曲线法计算的结果相比,误差小,应用效果良好。因此,测井方法在石盐勘探评价中具有广泛的运用前景。

关 键 词:可可西里  古近系  石盐  测井  工业品位

Abstract::Multilayer halite Layer develop in Yaxicuo formation of Hoh Xil area.In order to effectively identify the depth and thickness,and predicate of its industrial grade,the establishment of halite index curve based on the normalized natural gamma ray and density is used to divide the halite and clastic rock.Compared with the method of intersection graph and logging overlap,its accuracy is higher.Using halite indicative curve and halite sample test results,a relationship to predict industrial grade of halite was established.Compared with the results calculated by the natural gamma method and the porosity curve method,the error is smaller and application effect is better.So the logging method has widen application prospects in halite exploration and evaluation.
Keywords:Hoh Xil   Paleogene   Halite   Well log   Industrial grade
