Title: Sedimentation response in rift basin to tectonics and its control to hydrocarbon distribution-An example of Saihantala Sag in Erlian Basin
Abstract: It was thought that a single rift was controlled by single boundary fault and there was only one depocenter. However, after studying Saihantala Sag in Erlian Basin, the author found that the depocenter was shifting. According to the evolution of deposition in three dimension, the East boundary fault in the sag was linked after K1 bt1 Formation was deposited, at the same time, the regional stress fields changed from northwest oriented to northwest-west oriented. In the forming history of hydrocarbon pools, the main faults propagated and linked alternatively, and the transfer zones were the favorable places of hydrocarbon accumulation, which controlled the distribution of hydrocarbon clearly. The deposition controlled by propagation and linkage of boundary faults has instructive significance to exploration work in rift basin.
