摘要：
The concept of "fault-karst" trap (reservoir) was proposed in 2015 on the basis of author's experience from carbonate exploration and reservoir development in northern Tarim Basin and their understanding of reservoir/accumulation-control characteristics of fault deformation, karstification and dissolution in the fault zone. Since then fault-karst reservoir has become a new target in carbonate exploration and development in the Tarim Basin. This study further demonstrates that fault-karst reservoirs are not only significantly different from the traditional karst (buried hill) reservoirs, they may also have different genetic types and structural characteristics under different karst environments and structural settings. Fault-karst traps can be divided into three subtypes according to the dissolution conditions and fracture types, and they are characterized by fault-karst storage, deep-fault accumulation, trap structure, vertical dredging, multi-layer accumulation, and segmented reservoir formation. Fault-karst trap (reservoir) is important to oil and gas exploration and development and should be comprehensively studied. © 2023 Science Frontiers editorial department. All rights reserved.
