White leopard areas located within the white leopard Township, Wuqi County,Shaanxi Province and Gansu Province the Huachi Joe Township, an area of about1670square kilometers, is the landform of the Loess Plateau, constructed in the Ordossedimentary basins in northern Shaanxi slope southern overall was a gentle Westpourmonoclinic, the inclination of less than1°, undulating smaller axial formed by the localdevelopment of differential compaction nearly east-west or north-east to the nose-shapeduplift. Major oil-bearing strata of Triassic Yanchang and Jurassic Yan’an Formation theTriassic Yanchang set clastic rocks inland lakes-Delta deposition.In this paper, a method of combining multidisciplinary carry out a fine stratigraphicdivision and correlation, sedimentary microfacies, logging the second interpretation,reservoir fine description and evaluation of geological research. Division and correlationof high resolution sequence stratigraphy of the study area in accordance with the modernsequence stratigraphy principle, accurate sequence stratigraphic framework and reservoirsubdivision framework, reveal the genetic type of sand body and microfacies spread.Detailed discussion of the reservoir sandstone petrology characteristics and reservoir spacestructure characteristics. To carry out oil and gas controlling factors and hydrocarbonaccumulation enrichment Distribution Law; construction production potential analysis andevaluation, the focus in abrasive belt continued construction capacity potential and Eastand West belt scroll built production potential analysis; carry out the the favorableconstruction production target area preferred carry out the construction of production scaleforecast. |
