| Kiln Gulf oil in the terirtory of Jingbian County of Shaanxi Province, the block is locatedin the Erdos basin two tectonic units in North Shaanxi Slope in central, East High and westlow monoclinal structure form, structure is relatively smooth, the local development ofstructural highs. The main oil-bcairng seires in Chang6reservoir, mainly developed deltafront distirbutary channel microfacies, distirbutary channel along the NE-SW distirbution, is atypical low porosity, low permeability, low pressure and low abundance lithologic reservoir.In this paper the kiln Gulf oil Tirassic Yanchang Formation Chang6reservoir as theresearch object, using sedimentary petrology, petroleum geology, reservoir engineeirng, theoryof knowledge, in order to logging, logging, oil testing data, analyses the characteirstics,structure of this area is the feature of sedimentary facies and sand body distirbution, thedistribution characteirstics and reservoir characteirstics focus on the development plan ofreservoir, Chang6reservoirs. Through analyzing the area showed that: by using a set of wellpattern development is more economic and reasonable; advanced water injection developmentway; well network system adopts rhombus inverted nine spot injection pattern.This study not only study of reservoir characteirstics in detail, and the next step ofdeployment and waterflood development direction, and provide a theoretical basis andtechnical support for the future development of the region. |
