大庆长垣中部扶杨油层构造特征及其对油气成藏的影响

bstract:The analysis of fault and seismic data interpretation of Fuyang reservoir in the Daqing placanticline shows the fractures are banded on plane and graben zone on the seismic profile.The characteristics of the fractures are numerous and small-scale.The fault activity of Fuyang reservoir go through four period:the deposition of the 1st member of Qingshankou Formation，the end of Qingshankou period, the end of Yaojia period and the end of Mingshui period. The structural inversion happened in the end of Mingshui period resulted the vertical migration of Fuyang reservoir in the early to lateral migration.We suggest the multi-stage movement of fault and the structural inversion happened in the end of Mingshui period obviously control hydrocarbon migration and reservoir-forming of Fuyang reservoir.
