The Research Of Reservoir Characteristics In Ⅳ 1 ～Ⅳ 3 Of The Central Regions Of Oilfield Of Jinglou

The oilfield of Jinglou is Located in anticline of Jinglou and Nasal shape tectonic belt of Gaozhuang in Western slope belt, The central regions of the oilfield of Jinglou including six areas.they are the zero area, the third area, the fifth area, the sixth area, The seventh area and The eighth area. The oily horizon in Central regions of the oilfield of Jinglou includes Oil groups ofⅡ,Ⅲ,Ⅳ,Ⅴ,Ⅵ. The water-oil relations are contradictions, during the development of reservoirs, in the combined parts and edges of Oily horizon in Central regions.Local areas do not understood in more aspects on the based of reservoir subdivision.TheⅣ1,Ⅳ2,Ⅳ3 of H3 MeMber of Major reservoirs are contradiction in water-oil relations,because of the influence of different Material sources, the Stacked Sand body, interchange of Different material sources, specially. The paper obtained some achievements,on the based of the comprehensive research in the central regions of the oilfield of Jinglou,Geology, logging, Production of tested , sedimentology , Logging geology , Reservoir geology and Sequence stratigraphy,utilized in The paper.1. Comparatived study, LJ7407 and L32131 determined Standard Wells, the top ofⅣand theⅣ6 determined marking-layer, based on this, the sections of skeleton were established. The author completed stratigraphic correlation, based on the combination of GR, RT and Microelectrode curve ,in Logging curves.2. The author researched the construction of the area, based on the subdivision contrast and the seismic data.3. The author determined content source direction of central regions of the oilfield of Jinglou, According to sedimentary environment in the area, analysis of paleo-provenance.Based on the detailed observations, description about sedimentary environment of region and five coring wells, and the analysis of granularity. The author determined that the area belongs to be sub-facies deposition of the front fan delta, and subdivided the sedimentary microfacies, established the relevant depositional model, according to superiority sedimentary microfacies of single well.4. The author subdivided the Layer segment of sand bodies in single well , and researched the profile and surface exhibition cloth of sand bodies.5. The author analysised the property of wells, based on the achievements of core material and Logging interpretation. The author researched the property of the reservoir, and reached a conclusion that the layers in central regions of the oilfield of Jinglou keep the better property, and the reservoirs ofⅣ1～3 belong to be the reservoirs of II～III.6. The author considered that the reservoirs ofⅣ1～Ⅳ3 in central regions of the oilfield of Jinglou are the reservoirs of different Hydraulic systems , and researched the factors of controlled in tne area , based on the sedimentary facies and Spread of sand body and layer.7. The reservoirs ofⅣ1～Ⅳ3 in central regions of the oilfield of Jinglou belong to be Lithologic reservoirs. The property of the reservoirs belongs to be the reservoirs of Big porosity-the middle and big permeability. The reservoirs are thickness, scattered, small Oily area, shallow buried and big porosity-the middle and big permeability. Overall, the layers ofⅣ2,Ⅳ3~2,Ⅳ3~1 andⅣ1~3 are better thanⅣ1~1 andⅣ1~2, which are small Oily area.
