Study On Reservoir Description And Mode Conversion Of Member ? Of Yulou Oil Layer In Jin92 Block In Liaohe Oilfield

Jin 92 block structure is located in the western sag of liaohe fault depression in the west slope south of jin 45 block area of the Midwest,the development of the layer to in shahejie formation a middle to upper reservoir sand and sand 2 xinglong station reservoir,for layered fault block of heavy oil reservoir.Layer in the purpose of this study ? group after 30 years of development development effect is good,but is now at later stage of steam stimulation,how to further improve reservoir recovery factor is the main purpose of this study.Papers focus on the study of reservoir description and mode conversion.Through to the block structure,sedimentary facies,reservoir oil-water distribution characteristics and so on carries on the careful research,finding out the remaining oil distribution law,identified in the steam drive development under the condition of well pattern,well spacing and injection-production patterns of various parameters,such as,completed the steam drive reservoir engineering design.Study think jin 92 block in ? reservoir group overall structural form is fault holding two nose structure combination,a total of nine fault developed.Regional study of sand body thickness thinning from north west to south east,sediment particles from coarse to fine,provenance from the northwest.Reservoir mainly distributed in the structural high part,local development degree affected by sedimentary,from the causes of its reservoir types for lithologic structural reservoir;From the occurrence of reservoir and oil/water distribution division,which is pure oil reservoir in ? group.From reservoir characteristics analysis,the late way transformation mainly steam drive.Through the research of this paper for the reservoir description of the same kind of reservoir,and the transformation development way choice,well pattern adjustment,well type optimization provides the reference.
