摘要
Because of the fake tectonic phenomenon caused by static correction of 2D seismic in loess tableland,it is believed that there is no fault in Mesozoic of Ordos Basin for a long time.Based on the layer leveled and lateral compression in 2Dseismic profile,multiple faults with small slip were discovered,and most of them were nearly vertical;NE-trending fault existed,and the fault zone developed after the combination of faults.The NE-trending faults might be Mesozoic tear faults which formed when basement faults reacted under the condition of right lateral wrench movement in Yanshanian,and they might develop in all-basin scale.By the superimposed contrast of the distributions of fault and reservoir,the relationship between the distribution of reservoir and the position of fault was significant,and the fault might be important migration pathway for hydrocarbon accumulation.Further deduction believed that the distribution of high plugging fault zone played an important controlling role on the development and distribution of reservoir in Mesozoic.The discovery of faults had vital significance on the prediction of basin Cenozoic tectonic evolution and reservoir distribution.
