Abstract The tectonic transfer zones have a great control on petroleum in the extensional rifted basin and petroleum usually accumulates near these zones. They are usually developed in the area where the stretching throws of the fracture have a decreasing-increasing change along the strike direction. The magnitude of subsidence of the strata tends to decrease near the tectonic transfer zones, thus the differencial of subsidence along the tectonic transfer zones leads to the development of a tectonopalaeogeographic framework of the alternated structural highs and lows. The faulted nose structures are developed adjacent to the tectonic transfer zones, therefore petroleum usually accumulates along the zones. The results show that the tectonic transfer zones are widely developed in the Banqiao Sag of Dagang Oilfield. Due to the development of the faulted nose structures near the tectonic transfer zones which are located in the hydrocarbon generation sags, the tectonic transfer zones are the favorable areas for petroleum to accumulate.
