| After30or40years of progressive development in lamadian oilfield,now in themiddle-late stage of reservoir development, oilfield workers struggling to find a variety ofscience and technology can ensure the stability of old oil field. This paper combined3-Dseismic data and logging, drilling geologic information, under the theoretical guiding ofSedimentology, Tectonics, Geophysical Logging and Geophysics, based on the thinking ofwell-to-seismic integration, detailedly studied Putaohua reservoir in Lamadian oilfield blockNorth-north one, extended the spaces of exploration and evaluation of Saertu reservoir,provided the technical supports for infilling adjustment in exploited zone, field extension andthe next evaluation.By the detailed well-to-seismic integration structure elucidation, identification ofcoherence cube and stratigraphic sepration ratio etc, seismic horizons were exactly elucidatedand the spread of faults were exactly defined, explain fault9,According those, we knew thestructural features and the spreading characteristics in space and plane of faults in PU IIformation of Putaohua reservoir in research area.PU II formation of Putaohua reservoir in Lamadian oilfield shows many wells, quickphase transformation of thick and thin reservoirs, We used well-to-seismic integrationreconstruction inversion to detailedly forecast the sand of reservoir in research area, we madeuse of the fruits of inversion to direct the sedimentary microfacies research, analyzing thechanging features of stream channel sand. Shed light the contact relations, spreading in spaceand distribution as well as scale of reservoir sand in research area.This paper comprehensive sedimentary microfacies, structure and reservoircharacteristics research fruits, it deepened the recognition of characteristics of structure andreservoir in developed oilfield, provide the geological basis for the adjust of oilfield waterinjection programmes in the late, the dense network deployments and remaining oilexploration. |
