摘　　要：榆林气田南区自2005年底在山2砂岩气藏整体建成20亿立方米年产规模后,已稳产8年,气田整体开发形式良好;但目前气田周边还未发现有利的产建接替区,为保持气田持续稳产,老井挖潜成为必要。以地质研究为基础,结合生产动态,采用不同挖潜选井原则对榆林南区44口低产、低压气井进行筛选;优选出两口井为挖潜对象,利用数值模拟对挖潜效果进行预测,并对措施经济效益进行评价。Since the end of 2005,the south block of Yulin gas filed has been produced for 8 years after it built up two billion annual production scale in Shan2 gas reservoir, the gas field developed in a good situation.But the field surroundings hasn＇t found any superseding pro- duction area.So as to maintain the sustained and stable production of the gas feld,the exca- vation of old wells potential becomes necessary. Base on the geology research,combining with production dynamic,screening in 44 low yield, low pressure wells with different principles, two of these wells are selected for tapping potential,using numerical simulation to predict the effects and evaluate the economic benefits of measures.
