The Study Of Optimization And Simplification For The Ground Engineering Techniques Of Changling Gas Field Denglouku Formation

Changling gas field is the main block for the gas development of Jinlin Oil Field, Denglouku formation will be the main area for the gas development to come. The gas components are alkanes, mainly the methane, the content of mechane is 91.54—91.87%, average 91.71%, the content of carbon dioxide 0.04-0.33%, average 0.19%, relative desity of the gas is 0.59. The average output of vertical wells is 2.0—3.0×104m3/d, the designed output of horizontal wells after staged fracturing is 7.5×104m3/d.The development of Changling gas field Denglongku formation varies considerably from that of the past in Jilin Oil Filed, through the study of gas gathering processes domestic and abroad, and through the recognization of regularities of gas well fluid contents changes, we conclude that the following technical processes are suitable for the gas gathering of Denglongku formation: gathering with low and medium pressure, consideration of the existing gathering stations and gas fields, reasonably determine the mechanism of system pressure and layout of the gathering stations and gas fields to realize the high efficiency of the gas development of Denglongku formation.Through the demestic investigation of gas field information automation, we undertook some experiments of computerized managements in the gathering stations and gasfields of Jilin Oild Fields, and we have got that computerized management applied in some gas fields of Jilin Oil Field.
