摘要
靖边气田已进入自然稳产的中后期阶段,主力区块气井井口压力低于9MPa,由于采用高压集气模式,增压开采潜力巨大。靖边气田面积大、井数多,非均衡开采严重,单一增压方式存在局限性,依据靖边气田的开发动态特征和地面建设现状,对比不同增压方式的适应性,优选了以区域增压为主、集气站增压为辅的混合增压方式。按照整体部署、分期实施的原则,精细气藏动态描述,将靖边气田优化为30个增压单元,增压时间2010～2015年。
Jingbian gas field has entered subordinate phase of natural stabilized production, where wellhead pressure in main block is lower than 9MPa. Due to the high-pressure gas gathering mode, there is huge pressure-boosting production potential. Jingbian gas field covers large area, with many wells and serious unbalanced recovery, single pressure-boosting mode has limitation. On the basis of development dynamic characteristics and surface construction situation, the adaptability of different pressure-boosting stimulations were compared, and hybrid pressure-boosting stimulation was selected which takes regional pressure-boosting stimulation as the priority and gas gathering station pressure-boosting as the supplementary. In accordance with the principle as overall deployment and phased implementation, fine gas reservoir description was made. Jingbian gas field was optimized into 30 pressure-boosting units, and its pressure-boosting duration is from 2010 to 2015.
