Research On The Control System Of Oil Extraction Joint Station Based On PLC

Gas reservoir of low productivity in Jilin oil field are distributed in Xiaochengzi,Fulongquan and Shuangtuozi,besides a strong sensitivity,most of which get dual production including liquid production and gas production.With a long term production pressure on the gas-field of Xiaochengzi,Fulongquan and Shuangtuozi,prohibition problems from liquid production become more and more serious.At present,for the reservoir producing liquid,string optimization technology for water drainage,foam dewatering technology and pump technology for water drainage are introduced.Hence,because of the study and application on the string optimization technology on water drainage and foam dewatering technology,which guaranteed the normal production in partial gas wells with liquid production,got a nice field application.Water drainage&gas production technology must be operates in the whole production.With a increased and deepen development,as well as an increased liquid production,the adaptability of the technology made a great difference due to the different production.The normal water drainage&gas production technology can not meet the present technology needs.So the effective water drainage&gas production technology must be studied to guarantee the normal production of the gas wells,as well as achieving the best productivity and benefit.According to the critical carrying fluid production theory of gas well,with calculation and analysis on 54 wells,a critical carrying fluid model adapted to the low pressure and low productivity gas field;though the application of string optimization technology on water drainage,it can relatively meet the water drainage needs in the early time;the foam dewatering technology is intensified,including the lab sift test and evaluation on Cheng9 medicine injection,evaluation on the foam and the field application on injection parameters adjustment,which improved the production effect.Through the technology study above,the water drainage needs of gas well producing liquid can be met basically.
