Reservoir Prediction On Putaohua Formation In Tai 121-1 Block Of Aona Oilfield

The 121-1 block of aona oilfield can be constructed in 2017,and proved reserves in 2013,which is planned to be used in 2016.It is difficult to predict the sand body with the general method.Reservoir do this,you need the block structure,reservoir geological characteristics correspond diachronically,according the geologic characteristics of putaohua reservoir Aona region,combining well seismic reservoir prediction technology of putaohua oil layer in the production of the reservoir prediction,i.e.,according the stratigraphic classification and correlation based and well seismic horizon calibration,using 3 d seismic data and combining the have finished drilling data,carry out the putaohua oil layer upon layer,fault interpretation,preparation of putaohua oil layer group of top and bottom To figure and depth structure figure,such as the implementation of the work area putaohua reservoir structure form,especially for small fault extension length,direction,orientation,obliquity,elements such as fault displacement.Comprehensive utilization of geological,seismic,logging data,using the well seismic joint technology,under the horizon interpretation framework,carry out a variety of seismic attributes analysis,through property and the analysis of stratigraphic section plane distribution characteristics of sand body and scale.The inversion method and its parameter optimization are carried out,and the inversion method suitable for this region is selected,and the spatial distribution of sand body in the formation of grape flower oil layer is predicted.Fine fine seismic interpretation and reservoir prediction for research,finally achieve intensive tectonic characteristics research,deepening the research on reservoir distribution characteristics,combining with the above research results,optimization of well pattern configuration and sand body,Suggestions of horizontal well,according to the growth of structure,fault,reservoir,optimization of horizontal well,horizontal well azimuth and length of horizontal well.
