海拉尔盆地呼和湖凹陷白垩系地震相
Seismic facies of the Cretaceous in the Huhehu Depression, Hailar Basin
摘要
Abstract
The petroleum exploration in the Huhehu Depression of Hailar Basin has become a new area for searching for reserves in the Daqing Oilfield, but no great breakthrough has been made owing to the lower study degree. 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, including parallel sheet, sub-parallel sheet, prograding, filling, wedge shaped, moundy, chaotic and wave-hummocky seismic facies. And their characteristics are described in detail. These seismic facies show differentiation in horizontal distribution and are successive and evolutionary vertically. Seismic facies are transformed into sedimentary facies through a comprehensive interpretation. The seismic -sedimentary facies model of each sequence is established according to the lacustrine sedimentary theory. The results show that the target sequences develop the sedimentary systems of alluvial fan, fan delta, braided river delta, lake and sublacustrine fan.关键词
