1. a particulate rock fine lamina sorting technique, it is characterised in that step is as follows:

  • Small-sized sedimentary structure information in fine-grained sediment and particulate rock is collected, measures, divides and big class classification by aMinor structure in fine-grained sediment and particulate rock is a lot, needs first to be collected arranging, measuring, screening, eliminates the false and retains the true, enterRow lamina, the big class of fine lamina are sorted out and analyze;

    B fine-grained sediment and particulate rock lamina attribute identification and classificationLamina attribute is the basis of lamina classification, and attribute is feature specific to lamina, including three aspects;

    B1 is based on the lamina of rigidity plasma and fine lamina;

    The lamina of b2 mixed layer formation and fine lamina unit;

    B3 lamina unit is the lamina based on organic matter and fine lamina;

    Lamina type is screened, classifies and is measured by c one by oneMainly carry out screening, classify and measuring in terms of following two;

    C1 macroscopic view is classified, and refers to lamina that naked eyes can measure and screen and fine lamina;

    The micro-classification of c2, is i.e. made by microscope and carries out the lamina examination of less rank, classify and measure;

    The thickness of the various laminas in fine-grained sediment and particulate rock is measured and classifies by dLamina thickness is reflection lamina feature and the critical data of evaluation, is also the useful data evaluating shale characteristics of reservoir, fromUnder several aspects measure and classify;

    D1 to the single lamina thickness observing and screen measure one by one and add up;

    D2 classifies as a kind of lamina group for the lamina that attribute is same or like, and measures respectively and add up;

    D3 is same or like for attribute generally, spatially has certain regularity of distribution or superimposed pattern, incorporates into as a kind of lamina sequenceRow measure and add up;

    Laminated forms feature is identified and classifies by eThe origin cause of formation that laminated forms is formed with lamina is relevant, and morphological characteristic plays an important role, from following several for the real value evaluating laminaIndividual aspect is described and classifies;

    E1 sequential like lamina, is i.e. that lamina and fine lamina are seriality distribution within the specific limits, and interruption interval is less, lamina thicknessThe most stable;

    Continuous shape lamina between e2, is i.e. that lamina and fine lamina are inter-continuation distribution within the specific limits, has interruption discontinuous, but generallyCan follow the trail of, along certain orientation and spatial distribution;

    E3 lenticular lamina, is i.e. that lamina and fine lamina are lens distributions within the specific limits, is interrupted interval very significantly, and lamina is i.e.It is lenticular body, but can also follow the trail of generally, along certain orientation and spatial distribution;

    E4 mixing shape lamina, is i.e. that the material composition of lamina is mixing, and the distribution of lamina is variation, spatially follows the trail of and is probablyIt is discontinuous or lenticular body by continuous transition;

    F, on above-mentioned working foundation, establishes lamina sequence, sets up fine lamina taxonomic hierarchiesLamina and fine lamina system are made up of following;

    F1 lamina and fine lamina thickness are main classification, i.e. using thickness data as main line, carry out thickness classification, are aided with attribute and thingThe description of matter;

    F2 lamina and fine lamina attribute are main classification, i.e. classify with attribute character, and thickness is as auxiliary parameter;

    F3 lamina and the classification of fine lamina characteristic material arrangement, i.e. classify with material property, and thickness is as auxiliary parameter, attributeAs describing content;

    F4 lamina and the classification of fine lamina spatial shape feature, be i.e. quantitatively described with thickness, lamina interval pitch parameter, be aided withAttribute and the description of material property;

    The classification of g aggregative indicator and evaluationOn the basis of above-mentioned steps, aggregate qualitative and quantitative classification ownership and evaluation, finally make classification schemes.
