Fine Reservoir Description Of YuLou,XingLongTai Oil Layer In Jin-45 Block

From the oil-field development,the fine reservoir description mean to carry on a series of research for announcing to public remaining oil distribution regulation in the end of development.The research purpose of《YuLou,XingLongTai Oil Layer Fine Reservoir Description of Jin-45 Block》is exactly to provide a basis for next work,fully scoop out development potential of Jin-45 block through fine reservoir description,aiming at the problem that appear in the development processes of Jin-45 block,and have to lead meaning importantly to raise use degree of reservoir and recovery efficiency ,carry out to develop efficiently.This research carried on the system layering to 1620 wells of the whole area,dividing 4 reservoir group,12 sandstone group, 24 subzone.On the foundation of the fine layer,through the technique of seismic data coherent body analysis,3D visual technique, seismic attribute analysis...etc.combining drilling data,recarry out Jin-45 block's faults and increase 19 faults.Aiming at the phenomenon that the water breaktrough time of structural high part is earlier than structural low part in Jin-45 block,carry on a research towards fault closing mechanism,this is also a bright in this research, and the structure line is encrynt from the original 25 m to the 5 m,carry on a tiny structure research,discover 83 forward small structure, 39 negative small structure.Through well logging second interpretation of 1567 wells in Jin-45 block,build up the logging model to explain and oil,water,dry layer standard, carry on a research to the part of low resistivity oil layer and water flooded reservoir, and make each oil-water interface.Found a reasonable research method in the water flooded research:First is recover history,to the well brought in the same age,find watered out order and source through watered out time,to well brought in age,find watered out time and source through oil recovery period of no water, and combining deposition microfacies,carry on the research of watered distribution regulation,the study have important meaning to conversion and development.This research build up the structure and attribution model of Jin-45 block through 3D geology mold,lay the basis in order to study remaining oil distribution regulation, but the research calculate the surplus oil of 24 subzone through two kinds of methods of remaining recoverable reserves and numerical modeling,and reestimate reserves to subzone, increase 3,020,000 tons comparing reserves in 1995.through comprehensive research, In the high part of structure and surplus oil,deploy 23 development wells, anticipating to set up a productivity 25,000 tons/year.
