Relying solely on logging for inter-well reservoir prediction, there are many difficulties, and a large earthquake with a horizontal density advantages of using wells with inversion of seismic reservoir prediction techniques, can effectively improve reservoir prediction accuracy. Using this method blocks north of Daqing Changyuan development and application of detailed reservoir description and seen results, arranged according to sandstone inversion profile A-215 horizontal wells, the drilling rate of 92% sandstone, the cumulative oil production is currently well 9686t, showing a good prospect.
