油田开发后期井间砂体识别
Cross-well sand-body identification in the oilfield development late stage
摘要
Abstract
After more than 50years of the exploration and development,Daqing Changyuan Oilfield is now in the stage of dense well pattern and single-bed production. The development geological task is to identify the connectivity of sand bodies and the narrow channel boundary between wells.Based on high-density 3Dseismic data and well development information,a sand body prediction model for typical Changyuan Block is established with integrated well-seismic data inversion.Single- channel boundary of composite sands and narrow channel sandbodies between wells are identified by the geologic statistics inversion.It is concluded that the integrated well-seismic data inversion synthesizes the advantages of vertical and lateral high density information, and it is suitable for cross-well sand body identification in the oilfield development late stage.关键词
