Abstract

With increasing difficulty and complexity of seismic exploration for oil and gas, high-density seismic exploration has been widely used as the main technology to increase oil and gas production. Pre-stack time migration technology in frequency-wavenumber domain use non-recursive pre-stack F-K time to achieve migration imaging by considering conditions of metastable phase in common offset domain. Compared with Kirchhoff pre-stack time migration, it has the characteristics of high imaging precision and the ability to process data in steep structure without producing operator aliasing. Model data and real data processing has verified that processing data by pre-stack F-K time migration method in high-density seismic exploration is correct, effective and practical.
