84-6 block located towards the northern Songliao Basin Chaoyanggou terrace Central Tuen anticline crosses the north wing, the purpose of Fuyu reservoir horizons. By analyzing geological data, based on previous research on the seismic interpretation of the results of analysis of sedimentary characteristics and structural characteristics of the study area,referring to structural features and sedimentary characteristics of reservoir draw cross-sectional analysis of a plane water distribution of different layers and vertical distribution of water, according to the characteristics of the water distribution block, structure analysis, fault and sand body control action accumulation of determining reservoir types; in these studies based on the different layers of water distribution factors were analyzed to determine the main factors.By dissecting the reservoir 194 drilling study concluded that anticline reservoir wells 169,fault block reservoir wells 13, fault lithologic reservoir wells 9, lithologic reservoir wells 3. At different water distribution characteristics of reservoir types, based on the use of test oil well logging, measuring results, combined with configuration, fault and sedimentary studies on single well, and cross-sectional plane water distribution in the study area are summarized from the sand unit of Inoue water distribution can be concluded that the presence of the vertical distribution of water five types, namely, a full pure oil-wells, water type oil, with oil in water type, water interbedded type, all well water type. pure oil region, Fu II, III oil group Rotary wing steep anticline structure and lithology in local control: on the plane for three oil reservoir distribution group drawn from the analysis lithologic oil blocks appear aqueous layer folder, folder water reservoir. For the distribution of reservoir type plane, region controlled by the structure of the main factors affecting the development anticline reservoirs,block off the nasal area and easy to form small fault block reservoir and some easily formed nearby in fault lithologic reservoir, the region is less lithologic reservoir development.Accumulation Controlling due to:the source reservoir pressure control reservoir scale,tectonic control hydrocarbon accumulation and differentiation of sedimentary facies and reservoir distribution control.
