Analysis and countermeasures for adaptability of drainage and recovery technology for shale gas
Youqicang pingjia yu kaifa, 2020 Due to the own application conditions of the electric submersible pump and other drainage and gas recovery technologies, they cannot adapt to different drainage and gas recovery periods of shale gas wells in the south block of Pingqiao. In order to solve

Reasonable Pumping Depth for Drainage and Gas Recovery of Shale Gas Wells
International Journal of Heat and Technology, 2020 For shale gas wells, in the initial production stage, the liquid production is large, and the lifting process is needed to assist the drainage. However, for gas wells, especially shale gas wells, the ultimate purpose is different from that of oil wells, and the current design method of pumping depth cannot meet the field requirements. Starting from the

Evaluation and improvement of CO2 assisted gravity drainage for enhanced oil production in China
Energy Reports, 2023 In view of the diversity of petroleum reservoir types, most petroleum reservoirs have very strong heterogeneity in properties. For many water flooding reservoirs, with the continuous water injection process, the effect of enhancing oil recovery begins to
