The critical erosion output of a gas well is one of the main factors mostly considered in realizing the allocation of gas wells in the underground gas storage(UGS).For this purpose,according to the canonical calculation model and in combination with the principle of gas reservoir engineering,the equation applicable in the calculation of critical erosion output of gas wells in the Hutubi UGS is derived after a detailed study.On this basis,the major factors influencing the erosion output are well studied such as string inner diameter,flow pressure,gas temperature,etc.In addition,the corresponding influencing rules are analyzed,including that erosion output is in direct proportion to string inner diameter as well as flow pressure,but in inverse proportion to gas temperature,and it is influenced significantly by the change of string inner diameter.Moreover,on the basis of the substantial literature and data of the other UGS projects,the practical case of the Hutubi UGS is studied and the empirical constant of C-value for the gas wells of this storage is determined.Then,from the perspective of erosion output,a Φ114.3 mm string is optimally selected as the vertical well string of gas wells in the Hutubi UGS.Finally,the erosion rules of relief valves is also studied and it is believed that in the practical actual gas production phase,the phased erosion will appear in the Φ88.9 mm relief valves,which must be checked regularly and replaced to ensure the regular service.

Fracture treatment has to be done for a higher yield from the Kelameili volcanic gas reservoirs due to their unique features including fracture-pore dual medium,hard volcanic rocks,poor petrophysical properties,well-developed natural fractures,and extremely low natural deliverability,etc.However,the complexity of the reservoirs brings much trouble to fracturing operation,such as the fracture split and extension mechanism being not recognized clearly,fracture fluid being at a seriously high leakage,artificial fracture being contorted or multi-fractured,fracture aperture being narrow and small,sand bridge being easily formed,and reservoir temperature,the gradient of open fracture and the work pump pressure being so high,and so on.Therefore,through theoretical studies and field application analysis,we developed a set of reservoir reconstruction technology with advantages of thermal stability,high-pressure resistance,sand bridge control,depressing filter loss,quickening backflow of fracturing fluid,etc.Field practices show that this set of reservoir reconstruction technology helps enhance obviously the gas yield of the Kelameili reservoirs after fracture treatment,and significantly improves the success ratio of fracturing,thus,providing robust technical support for further fast development of the volcanic reservoirs in the Kelameili gas field.This will be good reference for the development of similar gas fields.
