Study On Detailed Interpretation Of Structure And Lithology In The East Part Of Northern Saertu S-P Oil Layer

Saertu oilfield in Songliao basin of Daqing placanticline, north of Saertu developmentzone of east pure oil, after30or40years of waterflood recovery, has entered into high watercontent development stage, old oilfield’s production more difficult, the structure of theconventional explanation can not satisfy the need of the fine oil field exploration anddevelopment. Therefore, this paper comprehensive3D seismic data, Drilling and Loggingdata, in sedimentology, logging geology, structural geology, geophysics for theoreticalguidance, first based on the idea of well-to-seismic integration, expand the reservoir spaceexploration and evaluation, for the fine geologic research of sa-pu reservoir in eratern northSaertu oilfield.Fine descriptions of structure has important influence on oilfield development effect,most previous structure interpretation is given priority to the seismic, calibrating downholeseismic mainly based on horizon, breakpoint information can not be well combination withthe seismic. This study combines well-to-seismic comprehensive information is applied tostructural interpretation, the horizon and the breakpoint information through fine syntheticseismogram calibration to seismic, in combination with seismic lateral continuity andbreakpoint accuracy of well information advantage, achieve well-to-seismic integration withthe structural interpretation research. Through the seismic multi-attribute analysis technology,the lithology identification of river sand body. Finally, with the method of using thewell-to-seismic integration, prediction of reservoir sand body space distribution, distributioncharacteristics and scale. On this basis, it deepened the recognition of characteristics ofstructure and reservoir in developed oilfield, provide important theoretical and practicalsignificance in the late of remaining oil exploration.
