Abstract:

Thin layer sandstone prediction is the key problem in reservior description.In this paper,the structure,physical parameters,lateral variation of a reservoir could be accurately predicted by the technology of comprehensive constrained seismic inversion.This method improved the resolution of the impedance profile and the reservoir prediction.This method was used in the reservoir description and assessment of Eogene thin layer sandstone reservoirs in Gaoyang Region and was proved to be effective.The reservoir trap types,accumulation regularities as well as exploration targets in the area were predicted.

Key words: comprehensive constrained inversion, reservoir description, Eogene System, Gaoyang Region
