CO2 geologic sequestration is a new method to reduce global climate change and improve oil and gas recovery. However

the potential evaluation of CO2 geologic storage at small and medium scales is rare. Sikeshu sag is a secondary tectonic unit belonging to the northern Tianshan piedmont thrust belt in Junggar basin of Xinjiang.Through the collection and study of regional indicators

reservoir parameters

trap indicators

gas source parameters and traffic environment indicators in the Sikeshu depression area

this paper proposes an adaptive assessment method for CO2 geological storage potential of the Sikeshu depression in Junggar basin

Xinjiang

and calculates the CO2 sealing stock through the potential evaluation formula. The results show that the sequestration potential of the Sikeshu depression is generally suitable

and the theoretically proven reserves can achieve CO2 sequestration stock of 92.88×108 t. The study provides a new direction for implementing CO2 geological sequestration in the Sikeshu depression area and other blocks of Junggar basin

and provides reference value for subsequent relevant studies.
