Characteristics and Controlling Role in Hydrocarbon Accumulation of Strike-Slip Faults in the Maigaiti Slope

The Maigaiti Slope is a significant oil-gas-bearing field in the Tarim Basin. Based on 3D and 2D seismic data, systematic interpretation, stage sorting genetic analysis of strike-slip faults were carried out for first time. relationship between hydrocarbon accumulation was studied combination with fine dissection reservoirs. study suggested that: (1) Staging segmentation characteristics are evidently presented Slope. According to active periods, can be divided into early Caledonian period, late Hercynian Himalayan period. plane distribution characteristics, west Segment, mid-Maigaiti Madong Bachu Segment. main periods different sections remarkably different. This suggests that it response multi-period multi-directional tectonic movements, which primarily dominated by migration evolution Hetian paleo-uplifts.
