1. portray a method for coal measures fine-grained sediment structure, comprise the following steps:

  • 1), coal measures pulveryte structural parameters gather, comprise the stratum collection position of core sample;

    2), the identification at particulate microtexture interface and description, comprise and utilize the micro-microtexture type of high-power microscope identification, rock type in fine-grain structure, measure fine layer thickness, grain diameter, mud between the fine layer of particulate, carbonaceous dividing layer spacer thickness, vertical sequence relation, and record interface location;

    3), the multivariate analysis of fine-grained sediment structure log data, comprise collection, process, logging technology identification particulate microtexture type digitizing;

    4), fine-grain structure interface, cycle, hierarchical description and portray, Cheng Tu;

    5), carry out fine-grained sediment textural classification, quota portray, set up coal measures fine-grain structure model and staging hierarchy.
