| Summary: | Reservoir with low-permeability is the future object of oil exploration and development. After multiple rounds of screening, the remaining reserves have poor grade. Therefore, the applicable conditions of development technology are the key factors for whether the reservoir can be produced. Taking SINOPEC low-permeability reservoirs as an example, it is discussed in this paper for the status of development technology and production conditions of proved undeveloped reserves in low-permeability reservoirs with different permeability levels since the 12th Five-Year Plan. Moreover, the classification of development potential of undeveloped reserves was carried out. Combined with the existing types of hard-to-develop reserves and technological development trends, the future technical requirements and research directions of low-permeability reservoirs were further clarified.
