Quantitative prediction of structural fractures in the Paleocene lower Wenchang formation reservoir of the Lufeng Depression

Currently, the lower Paleogene Wenchang formation in Lufeng Depression is primary focus of reservoir development. The structural fractures that have formed inside it not only serve as principal path for oil migration, but also storage space. As a result, distribution features are crucial future petroleum exploration and development Depression. At same time, with quantity conventional reservoirs on decline, critical to determine fracture criteria deep unconventional reservoirs. In this work, used research stratum. Then, based existing logging data region, distinct physical properties different rock kinds calculated. simulation results paleotectonic stress field study area using finite element numerical software ANSYS show high-value areas maximum uplift belt low uplift, low-value 13 Sag gentle slope north middle-low uplift. density quantitatively predicted after simulation, which shows good agreement between anticipated actual observed values, an average error 13.61%. findings may provide new ideas exploration. cited as: Li, H., Yu, F., Wang, M., Y., Liu, Y.
