靖边气田冬季高峰期供气适应性研究探讨

靖边气田是长庆气区主力区块,随着最近几年长庆气区下游用户不断增多,特别是冬季高峰期用气量快速增加,靖边气田原料气最高产量已超过2 000万m3/d,气田调峰压力大,责任重。为此,根据气田冬季用气高峰期生产计划,从靖边气田集输管网、天然气净化厂、部分调产井、非计划关井等方面进行了适应性分析,有针对性地提出改造措施和调整建议,从而保证气田冬季安全、平稳供气,保证优势区块的产能发挥,满足冬季高峰期用气的迫切需要。

Discussion on Gas Supply Adaptability at Winter Peak Consumption in Jingbian Oilfield

Jingbian Gas Oilfield is the main gas production area of Changqing Oilfield. Along with increasing downstream consumers in recent years, especially at winter peak gas consumption, the maximum feed gas output of Jingbian Gas Oilfield is over 20 Mm3/d. So the burden of peak gas regulation on the gas field is heavy. This paper analyzes the gas supply adaptability according to the gas field production plan for winter peak comsumption, which includes the respects of gathering and transportation pipeline network, natural gas purification plant, partial wells for gas production regulation, nonscheduled well shut-in. It brings forward pertinent reformation measures and regulation proposals in order to guarantee the safe and steady gas supply at winter peak consumption.
