Application of high frequency expansion processing technology in Bohai Sea H oilfield development

The Bohai Sea H oilfield reservoir is the shallow delta facies middle-fine sandstone,sedimentary micro facies are mainly the distributary channel.The convention seismic data is limited to the resolution of sand shale thin interbed,brings great difficulty and risk to the reservoir description and oilfield development design.The high frequency expansion processing technology adopted the compression wavelet to avoid the difficult problem in obtaining the wavelet,this might enhance the resolution of the seismic data in large scale,enrich various geological information.Meanwhile maintain the previous signal to noise ratio,relative amplitude relation and time-frequency characteristics of seismic data,which has provided the reliable basic data for the reservoir fine description and the well position design adjustment,and gained very good development progress for the oilfield.
