ABSTRACT
The Yaken uplift is located in the southern slope of Kuqa piedmont depression in the margin of southern Tianshan. This uplift possesses favorable hydrocarbon accumulation conditions, characterized by high-quality source rock, multi-sets of reservoir-cap rock assemblages, and several types of traps. In addition, these conditions match fairly well. Based on previous studies on petroleum geology, this work also describes the hydrocarbon enrichment conditions according to the latest exploration results, and evaluates the petroleum potential. Stratigraphic traps of gas lateral migration along sandstone body and structural traps of gas migration along unconformities, faults, and sandstone are favorable hydrocarbon accumulation models in the Yaken uplift. Traps related to subsalt structures are the most prospective exploration targets in the Yaken uplift.
