Research On Channel Sand Bodies Tracing And Rolling Evaluation Of Lithologic Reservoir Of Yang Erzhuang Oilfield

The Yang erzhuang oil field is located in the northeastern part of the Yang erzhuang-like structure of the Huang hua Depression,which is an inverse traction(dome anticline).Drilling confirmed that the development of the Quaternary plain in the area,the Upper Tertiary Minghua town group and Guantao group,the lower Tertiary Dong ying group;the main oil layer for the Tertiary Minghua town group and Guantao group.Previously,according to the structure of oil to find ideas,around the central uplift with anticline,broken nose for exploration and development.From the current drilling situation,the structural belt has been fully developed,must be in accordance with the idea of lithologic exploration and exploration,along the structure around the implementation of rolling expansion,looking for river sandstone lithologic reservoirs,drilling in the Yang erzhuang north slope of Zhuang 83 Well,In Minghua town group to see a good oil and gas show,showing the slope of the prospect of lithologic exploration.The Yang erzhuang area is developed by the source,paleo-terrain and tectonic setting.The river facies sedimentary system belongs to the sand and shale reservoir and cap rock,and it is found that the sandstone is sandwiched,drilling,expanding the oil-bearing area and improving the oil and gas reserves.The results show that the reservoirs are predicted by the fine geological structure,and the reservoirs are predicted by the new geological data.Sensitive parameters,combined with stratigraphic section,three-dimensional visualization,seed point automatic tracking and other technologies,found more than 50 river channel sand bodies in different layers in the Yang erzhaung area.Finally,the oil source conditions,oil and gas migration modes,To the sealing conditions,and the use of frequency attenuation properties of oil and gas prediction,preferably multiple wells,to guide the deployment of exploration.
