本文对伽马测井分层解释方法的基础参数——形态系数的物理意义作了详细的描述,介绍了形态系数在地质脉冲函数表示下的计算通式,提出了形态系数的近似模拟公式。这个模拟公式可应用到野外形态系数的实测。文中列举了大量的模型实验和野外实测数据和伽马测井资料的对比结果,论证了该方法的合理性,近似模拟公式的可靠性和可行性,以及以形态系数为基础的分层解释方法较反褶积法具有更高的分层能力。
In this paper, the physical meaning of morphological coefficient, which is the basic parameter of stratified interpretation method of gamma logging, is described in detail. The general formula of morphological coefficient under the representation of geological pulse function is introduced, and the approximate simulation formula of morphological coefficient is proposed. This simulation formula can be applied to the field measured form factor. The article lists a large number of model experiments and field data and gamma logging data comparison results demonstrate the rationality of the method, the approximation of the reliability and feasibility of the simulation formula, as well as form factor-based hierarchical interpretation method Deconvolution method has a higher ability to stratify.
