元坝高含硫气田一期、二期工程建成后将达到每年34亿立方米净化天然气的生产能力。为提高川气东送管道供气规模和效益,元坝气田所产天然气在合理满足当地用气需求的基础上,通过川东北~川西输气联络线普光至元坝段管道向川气东送管道提供补充气源是必要的。目前增压站出站压力约5.0MPa,但川气东送管道进站压力已高达7.6MPa,因此为了外输元坝气田天然气,必须进行增加压力,将天然气外输压力将从5.0Mpa左右逐步上升至8.0Mpa。
Yuanba high sulfur gas field a, two projects will be completed after the annual 3.4 billion cubic meters of purified natural gas production capacity. In order to improve the scale and efficiency of gas supply from Sichuan to East Gas Pipeline, the natural gas produced in the Yuanba gas field will meet the demand of local gas supply on a reasonable basis. Pipeline to provide additional gas source is necessary. At present, the outlet pressure of booster station is about 5.0MPa, but the pressure of entering pipeline from Sichuan to East Gas Station has reached as high as 7.6MPa. Therefore, in order to export natural gas from Yuanba gas field, it is necessary to increase the pressure and gradually increase the pressure of natural gas from 5.0Mpa Rose to 8.0Mpa.
