Abstract
We investigated the geological factors associated with unsuccessful exploration wells in the northern margin of the Qaidam basin to better understand their cause. The structural situation, the hydrocarbon accumulation mechanism and unsuccessful well data collected from 1996 to 2005 were studied. The results show that the main geological factors associated with unsuccessful exploration wells are a lack of effective source rocks and a lack of effective traps, as well as the migration-accumulation conditions that exist in this area. The basin was reformed by Meso-Cenozoic tectonic evolution. Multi-stage tectonic activities have both positive and negative effects on hydrocarbon accumulation. Source rocks distribution, effective migration channels, effective traps and the tectonic evolution effects on hydrocarbons should be the key objects for further studies.
