Title: Fault Distribution Characteristics and Its Influence on Hydrocarbon Accumulation of DB1 Gasfield in Kuqa Depression of Tarim Basin
Abstract: DB1 gasfield is situated in the western part of Kelasu structural belt in Kuqa depression,the gas reserve in DB1 is more than 1 000×108 m3.The structural and geological conditions are very complicated,there are thick gravel areas and high mountains on the surface,evaporate salt bed developed underground.The structural styles are mainly fault-propagation folds above the salt layers and fault-bend folds under it.The research concludes that DB1 structure is complicated,in which the faults control hydrocarbon's accumulation and structural characteristics,not only influence the reservoir,but also connect to reservoir and source rock,and decide the condition of the reservoir preserved or destroyed.Above all,it is the key factor to study fault characteristics which could make us know DB1 gas field better.
