As oil and gas exploration has expanded to deeper and more complex tectonic areas, understanding the problem of fault-stress perturbation patterns under different stress backgrounds has become very urgent. In this study, to address the scientific problem in which the geostress perturbation pattern of deep (> 4500 m) faults is unclear, the Kelasu tectonic zone in the Kuqa depression was taken as the research object, and well logging data, seismic data and geomechanical modeling methods were used to systematically reveal the quantitative influence of the fault dip angle on in situ stress. The quantitative effects of the fault dip angle on the geostress under different stress types were investigated. The image logging data were used to identify wellbore breakouts and induced fractures, and the current geostress direction was confirmed to be nearly  \nN‒S. A geological model of reverse faults with different dip angles was constructed on the basis of equilibrium section technology. The finite element numerical simulation method was used to analyze the relationship between the fault dip angle and geostress under three stress mechanisms: normal faulting, stress conversion and strike-slip faulting. The results show that in the normal fault stress field, the horizontal maximum and minimum principal stresses both decrease with increasing fault dip angle. Near the stress transformation zone, the principal stress increases slightly with increasing dip angle, but the control by faults weakens. In the strike-slip stress field, both increase significantly with increasing dip angle. In addition, the fault dip angle affects the distribution pattern of shear stress: the shear stress of low-angle faults has a wider range, whereas that of high-angle faults has stronger stress concentrations. This study has important guiding significance for geostress prediction, drilling trajectory optimization and fracturing design of deep reservoirs.  \nKeywords Fault dip angle, In situ stress, Deep reservoir, Stress types, Numerical simulation  \nThe study of geostress in deep layers (burial depth > 4500 m) is the cornerstone of oil and gas exploration and development. The goal of this study is to determine the distribution pattern of the geostress field under ultrahightemperature, ultrahigh-pressure and strong-compression environments and its effects on reservoir physical properties and engineering safety1–3. At present, the study of geostress is carried out mainly through experimental simulations, well logging evaluations and numerical simulations4–7. In terms of experimental simulations, the magnitude of the principal stress in different directions can be revealed through differential strain experiments and Kaiser effect tests, which, together with the paleomagnetic orientation of the core, can be used to determine the direction of the present geostress4,8. In terms of well logging evaluation, the quantitative calculation of the magnitude and direction of geostress is realized through the combination of image logging (such as identification  \n1PetroChina Tarim Oilfield Company, Korla 841000, Xinjiang, China. 2Research and Development Center for UltraDeep Complex Reservoir Exploration and Development, CNPC, Korla 841000, Xinjiang, China. 3Engineering Research Center for Ultra-Deep Complex Reservoir Exploration and Development, Xinjiang Uygur Au","cbCaide2CzIkzp3E","https://ap.wps.com/l/cbCaide2CzIkzp3E","pdf",4841681,14,"English","# Introduction\n## Research motivation and objectives\n## Study data and methods\n# Methods\n## Fault dip-angle modeling and stress mechanisms\n## Finite element numerical simulation\n# Results\n## Normal fault stress field trends\n## Stress transformation zone behavior\n## Strike-slip stress field trends and shear-stress patterns\n# Implications","[{\"question\":\"What does the study investigate regarding deep in situ stress near faults?\",\"answer\":\"The study quantifies how the fault dip angle influences deep in situ stress disturbance patterns under different stress mechanisms.\"},{\"question\":\"How are the stress mechanisms distinguished in the analysis?\",\"answer\":\"The work considers three stress mechanisms: normal faulting, stress conversion, and strike-slip faulting, then evaluates how geostress responds to fault dip angle under each.\"},{\"question\":\"What key trend does the study find for normal fault stress fields as dip angle increases?\",\"answer\":\"In the normal fault stress field, both the maximum and minimum horizontal principal stresses decrease with increasing fault dip angle.\"}]","Quantitative analysis of the influence of faults on deep in situ stress under different stress types | PDF",1790732645,35]
