Abstract: In order to find high-quality dolomite reservoirs of the Ordovician Penglaiba Formation in Tahe Oilfield, three-dimensional seismic data and forward modeling were used to identify the anomalous seismic features, and geological genesis analysis was carried out. The results show that: (1)the anomalous seismic facies of Penglaiba Formation are characterized by multi-layered, short-continuous strong reflection, massive or layered external forms, distributed on one or both sides of faults, longitudinally constrained by horizon, and mostly terminated under the unconformity surface at the top of Penglaiba Formation. (2)The strong reflection seismic facies generally developed in the main part of the structure, and there are three favorable zones on the plane, which are relatively developed in the north-central and northwestern Tahe Oilfield. The distribution direction is consistent with deepfaults, showing NE and NNW directions. (3)Fault-hydrothermal process is the main genetic mechanism of the strong reflection seismic facies which is macroscopically controlled by tectonic framework and developed in the high part of structure. The deep faults are the main transport channels of hydrothermal fluids and terminate upwards in the overlying tight caprock. Therefore, high-quality dolomite reservoirs developed in Penglaiba Formation are of hydrothermal genesis, and the strong seismic reflection is an important seismic identification mark for high-quality dolomite reservoirs.

Key words: strong reflection seismic facies, deep faults, hydrothermal dolomite, Penglaiba Formation, Tahe Oilfield
