面向开发目标的高精度三维地震优势分析——以大牛地气田为例
For the development goals of high precision 3D seismic advantage analysis——Take Daniudi gas feild for example
摘要
Abstract
Taking the high precision 3D seismic applied in the Daniudi gas field development for example,we analyze the advantages of high precision 3D seismic data in the identification of small geologic body and oiliness of reservoir prediction,etc.On the observation system,high precision 3D seismic acquisition has increased greatly in frequency band wideth,number of coverage and space sampling density.This improved excitation and reception,so the seismic data quality has improved greatly.From prestack gathers data comparison,poststack profile contrast and lateral resolution,high precision 3D seismic has higher lateral and vertical resolution,which enable to identify small geological target.Higher folds and larger offset can meet the needs of pre-stack inversion technology.Combined with the actual drilling and testing data contrast,high precision 3D seismic can identify reservoir,and identify efficiently the oil-gas possibility,and drilling self-agreement reached 82 ％.This technology is then the effective technology of oil and gas field development.关键词
