Reservoir Prediction Method Research Of Sichuan Province LG Area In Leikoupo Formation

Lei-4 formation LG area reservoir on the verge of lagoon ping,the reservoir types is weathering crust karst reservoir of pore dolomite.The top of Leikoupo formation in the late indosinian movement field of weathering crust,it formed the weathering crust karst reservoirs because of the long suffering weathering leaching effect.Leikoupo formation and overlying the Xujiahe formation's mudstone formed a good weathering crust which was not integrated lithologic stratigraphic trap.This part of reservoir is thin and have large difference of physical property with Strong reservoir heterogeneity.Affected by the seismic resolution,fine reservoir description is difficult.This part of reservoir is thin and have large difference of physical property with strong reservoir heterogeneity.Affected by the seismic resolution,fine reservoir description is difficult.This paper,aiming at the above problems,which is based on old and well logging,seismic data,combined with 3d seismic data,research on reservoir prediction methods.The drill wear wells of LG area Leikoupo formation to conduct fine reservoir logging evaluation.It establish a set of suitable reservoir logging interpretation methods for the area of Leikoupo formation with reservoir parameter calculation and evaluation of the effectiveness of the reservoirs.On the basis of all kinds of methods for identifying fluid properties,we establish methods for identifying fluid properties of different types of reservoir and different lithology.We forecast the reservoir fluid property and use seismic attributes,such as the well constraint inversion technology to estimate the thickness of the thin reservoir in typical well to well profile in work area.We establish a set of methods to Fine logging evaluation and Seismic effectively reservoir prediction in this area of Leikoupo formation.
