The petroleum exploration in the Huhehu Depression of Hailar Basin has become a new area for searching for reserves in the Daqing oilfield. According to the seismic reflection termination relationship and the regional geological background, the Cretaceous in the Huhehu Depression can be divided into eight seismic sequences, Sq1—Sq8. According to the internal reflection texture and external geometric configuration and in combination with the parameters of amplitude and continuity, eight seismic facies are identified in the target sequences of the study area. And their characteristics are described in detail. These seismic facies show differentiation in horizontal distribution and are successive and evolutionary vertically. The results show that the target sequences develop the sedimentary systems of alluvial fan, fan delta, braided river delta, lake and sublacustrine fan.
