Abstract:

According to the different seismic reflection configuration characteristics of delta and fluvial reservoirs, seismic data interpretation, and sedimentary and sequence stratigraphic technique are used to analyse and recognize good reservoirs synthetically.In the east part of Rub Al’Khali basin of Middle East area, there exist some typical seismic reflection characteristics of braided channel and delta front sandstone.Based on these characteristics two sandbody reservoirs are recognized in TS3 basic level cycle of Silurian strata in T structure trap area in the west part of Rub Al’Khali basin, which are predicted as braided channel and delta front sandstone respectively.Reservoir, hydrocarbon accumulation and trap conditions show that the Silurian trap of T structure is a potential exploration region.The proposed well location on T structure is accepted and the later drilling result has verified the predicted reservoir sandstones.
