Secondary Migration Trend Based on Basin Modeling: A Case Study of the Cambrian Petroleum System in the Tarim Basin

Secondary hydrocarbon migration is an important aspect of oil-gas accumulation research. While previous studies have relied on geological and fluid geochemical characteristics to predict direction, these results are often limited by the number samples. In recent years, basin simulation has emerged as a valuable tool in research due its extensive algorithms adaptable modeling capabilities. It obvious technical advantages especially for resource evaluation areas with lower exploration degree scarce data. The deep oil gas Cambrian petroleum system Tarim Basin challenging area China. There been no breakthrough large burial depth ( generally > 6000 m ) long transformation processes. Therefore, predicting secondary become key solving this problem. study, first, thermal evolution Lower source rocks was recovered, three models were developed. process restored using geologic model paleotectonic latest potential information. By comparing results, four ultradeep developed: multisource, multiphase, multidirectional accumulation; single-directional single-source, accumulation. indicate that salient inheritance characteristics. dominant channels uplift slope beneficial accumulation, Katake west Bachu multisource charging east Tabei zones continuous single system. This provides new solution studying gas. reference areas.
