Study Of Fluvial-Delta Different Type Sandbody Innerstructure Of North 1-2area Saertu Oil Fields

Studing fluvial sandbody architecture can provide important academic evidence to realize the distribution of remained oil and hold peak or settled production. In addition to ,how to combine the facts of macroscopical and microcosmic, and how to combine the result of well network and fields outcrop,then instruct production and practice, which is the stress of this article.In this paper, the author paticular analysis 11 core holes and established The partition of strutum gyration of key layers in the area, then Stratigraphic analyzed the 225 well and identified microfacies of the target area, then established the mode of facies. The author analyzed the evolvement law of different type of channel combined sedimentary environment. Based on these research,the author analyzed the different type of fluvial sandbody architecture. In addition to, we summed the results of fields outcrop and fluvial engineering, established the geological thesaurus,ration the different type of fluvial channels shape parameters,then matched the logging interpretation model of shaliness,porosity unit, permeate ratio and hydrocarbon saturation originality, because using the measure of multianalysis and Network,the precision is higher than the result of onventionality, so laid the fundation of knowing the characterof reservoir. The last , the author analysise the character of plain and section with interpretation of logging, then obtain the fluvial sandbody architecture influenced to charaters of reservoir.
