Fine Tectonic Interpretation And Reservoir Prediction Of Shallow Layer In Shallow Sea Of NanPu

Through exploration of shallow NanPu in recent two years, it hasreceived good effectiveness, meanwhile the good hydrocarbon layer hasdiscovered in Nm, Ng of NanPu oil fields. Main oil sands of shallow seain NanPu are river course sands of fluvial reservoir. From all drillings inthis survey, we can find main features of this area that is thin thicknessgreat lateral changes, and big difference in hydrocarbon between blocks.Therefore, if good objects are going to be chosen in zones of palaeogene,the fine tectonic interpretation and reservoir prediction must be needed.Through analysis velocity of this survey and calibration of precisionhorizon,andapplicationofall kinds ofadvanced interpretation technology,this paper fine interpreted tectonic for six oil zones in upper palaeogeneandfouroilformationas anobjectinthisproject onthebasisoffinestratacorrelation, definition formation character of every strata as an object.This paper analyses tectonic framework of the survey, characters offracture and faults of hydrocarbon source, generalized forming pattern ofhydrocarbon reservoir and resurveying regularity. On basis of the formerwork, I have made further effort on reservoir prediction and attributeanalysis for the zone as an object in the project. At last, it is comprehensive evaluation for favorable tectonic and trap as an object inthe survey and provided five wells of suggestion. This paper is not onlyprovide valuable reference of science for exploration and development forhydrocarbon, but also provide experience and technology methods ofexploration and development in other shallow district by studying theproject.
