The Precise Study Of Fluvial Reservior In North The 1st Area At Putaohua Of Duanxi Of Saertu Oil Fields

Making full use of the theory of high-resolution sequence stratigraphy as the direction,and take the sedimentary theory as the foundation , the paper discusses the precise framework of stratigraphy problem of in the northern 1st zone faultage west in Sa'ertu. The research section mainly locates the oil layer of Putaohua which belongs to the first segment of Yaojia group, in order to go deep into the precise research, once again the layer is divided into several subgraduative small layers, namely PⅠ1—PⅠ7, and that the paper mainly researchs the content which concentrates on PⅠ1—PⅠ4 small layers, thereinto, PⅠ1 and PⅠ4 belong to the divided riverway microfacy, PⅠ2 and PⅠ3 belong to the meandering river and braid river sediment separately. Coming to light, the inhomogeneity of the fluvial facy is more complex than that of delta facy, this mainly is because the cause of formation and mechanism of the mudstone interlayer, distinguishment and distribution in the reservoir are more complex apparently. The inhomogeneity of the reservoir can been taken into the research from as follows several aspects: the inhomogeneity in the layers, the inhomogeneity in the middle of layers and the inhomogeneity on the surface of reservoir, basing on the above three aspects the paper describes the characteristics in the reservoir.Aiming at to have a lot of articles and cultural heritage in the domestic and abroad about the inhomogeneity of research which have already had very thorough research in this aspect, on this foundation, passing to check and consult domestic and international concerning of inhomogeneity each kind of cultural heritage , the paper selectively certains the theory of Daqing oil-field inhomogeneity research of reservoir.Aiming at the oil field has already entered into the period which high contains water, basing on the research of the inhomogeneity of reservoir, the prediction can been confirmed about the distributiong of maintained oil of reservoir, and which has the meaning of instruction. The calculation method of the artificial nerve network is a kind of very practical method, it is a kind of calculate way within mathematics, leading it to the geology realm, which is more important contribution that the logarithms learns the geology, and which makes the establishment of the geology model more accurate, this paper use for reference the theory and method of predecessor, and compute to permeatary with the principle of the artificial nerve network, through the production and practice, which has obtained the good result.
