Application Of High Precision Reservoir Prediction Technology In Huabei Oilfield

With the deepening of the exploration and development of the Huabei Oilfield in recent years,some of the main reservoirs with the delta front as the sedimentary facies and the main reservoirs have been paid more and more attention.And these reservoirs are usually formed with complex conditions,controlled factors,rich spatial types,heterogeneity,irregular distribution,making it difficult to determine the reservoir boundary,to understand the reservoir in the horizontal and vertical changes in the law and distribution characteristics,So high-precision reservoir prediction technology has become particularly important In this paper,the key factors that restrict the high-precision reservoir prediction technology are analyzed in detail,and the problems such as earthquakes and geology are combined with the relevant theories.In view of the problem that the conventional deterministic inversion resolution is low,A fully inversion method for high-precision identification of favorable reservoirs.In this paper,high-precision reservoir prediction methods such as geostatistical inversion method,frequency hopping method and constrained sparse pulse inversion method are studied in this paper,and are studied in many areas such as Raoyang sag and Baxian sag application.Through the comparison and analysis of the effect,the high precision reservoir inversion process suitable for different reservoir types is creatively summarized.Based on the application of reservoir prediction in many areas of North China Oilfield,this paper presents a high-precision prediction method based on rock geophysical analysis and suitable for multiple reservoir types such as sandstone thin interbeds,and improves the prediction results Of the resolution,and can more accurately describe the subtle changes in the reservoir.
