| Relationship between Passage Systems of Faults-Unconformities and Hydrocarbon Migration: A Case Study of the Luliang Uplift in the Junggar Basin |
| Faults are main passages for long-distance hydrocarbon migration from source rocks to pools in Luliang uplift, and Jidong fault has played a key role in this aspect. The existence of unconformities makes up a prerequisite for hydrocarbon accumulation, and the inhomogeneity of unconformities seems to be an important factor for the differences in hydrocarbon accumulations in this area. The passage systems formed by faults and unconformities are effective pathway networks which are very important for hydrocarbon migration and accumulation. The passage system formed by the unconformity surface of Permian strata and the reverse faults at depth is a key factor for hydrocarbon migration from source rocks to Jurassic strata, and the passage system formed by the unconformity surface at the bottom of Cretaceous strata and the normal faults in Jurassic strata is a necessary element for hydrocarbon migration from Jurassic to Cretaceous strata. |
