The main aim of seismic data processing is to correctly image subsurface structures. In most cases, the seismic lines for data acquisition may not necessarily be normal or parallel to structural trends. A new imaging method, Radon projection 3‐D pre‐stack depth migration, is presented to solve this problem, which extends the 3‐D migration by Radon projection to pre‐stack imaging. The full 3‐D pre‐stack data volume is projected onto a series of pre‐stack radial lines, which are migrated with common 2‐D pre‐stack depth migration. Then, the reverse projection on depth slice is applied to obtain the 3‐D migrated volume. Application of this new technique to a field dataset in the Tarim Basin shows improved horizontal resolution of the imaging section. Unconformity and some other small faults on the top of the anticline can clearly be seen on the image which greatly enhance seismic interpretation.

“…Wu and Xu [12∼15] implemented a 3-D fast projection migration method with Radon projection transformation and processed real data with preferable results. Huang et al [16,17] extended this projection migration to 3-D pre-stack imaging and implemented the Radon projection 3-D pre-stack time migration and processed real data.…”
