| Abstract: | Mud logging,well logging and petrophysical data show that the lithology of T1j22 formation are mainly limestone and dolomite,the lithology and formation depth are stable and seal rocks,which are widely distributed above and below the formation.Reservoir is mainly composed of pores,fracture type comes second.Filled fractures are highly developed, fracture dips varies and fracture effectiveness is poor. The reservoir property is characterized by low porosity and low permeability,the reservoir is not well deve... |
