A Study On Sedimentary Characteristic Of The Putaohua Reservoir In Pu62Well Area Of Pubei Oil Field

In this paper, guided by the high resolution sequence stratigraphy and reservoirsedimentology theory, comprehensive utilization log data, seismic data, geological data andcore data, high resolution sequence stratigraphic division and correlation, establish the closedskeleton section in the study region, research the general characteristics of the layerdevelopment and sand bodies sedimentary, anatomy of a single sand body, summed up thesand body tracking contrast method, reveal the sandstone distribution, research on theprediction of various genetic sand bodies, recognize the layer sedimentary model of thePutaohua reservoir in Pu62well area of Pubei oil field. The Putaohua reservoir in Pu62wellarea of Pubei oil field fluvial-dominated shallow-water delta deposition and developmentalrivel obviously shallow-water sediments logo, fluvial-dominated shallow-water deltadistributary channel deposit to development as the main characteristics of verticalperformance for early into the water, water withdrawal process. At the same time detailedanalysis of oil reservoir profile of the study area, this paper summarizes4kinds of reservoirtypes in the research area, and analysis of the main controlling factors of hydrocarbonaccumulation. Through the above work, find out the advantage reservoir sandstone ofuntapped area, improve the success rate of drilling, provide the basis for encryption andadjustment of injection production system and prediction of favorable reservoir of blank area.
