| 摘 要： | 致密砂岩储层改造技术在川西地区各气田得到了广泛应用，针对储层特征选用合理的改造技术措施对提高增产效果有明显作用，加砂压裂是川西致密气层普遍采用的改造技术措施，喷砂射孔一加砂压裂是针对致密，高破裂压力地层或井身结构特殊井的工艺措施，高能气体压裂－加砂压裂主要应用于高破裂压力和塑性强气层，酸化工艺措施在碎屑岩气藏仅限于天然裂缝发育且被钻井液侵入严重的气层。

| Abstract: | The stimulation technology of tight sandstone gas reservoir has been broadly used in many gas fields in Western Sichuan.According to the characteristics of gas reservoir,the selection of proper stimulation technology has obvious action on improving production response.Sand fracturing is the major stimulation measure in Western Sichuan tight sandstone gas reservoir.Sandblasting perforation-sand fracturing technology is to aim at tight ,high breakdown pressure gas zone with special bore frame.High-energy gas fracturing-sand fracturing technology is mainly used in high breakdown pressure and strong plasticity gas zone.Acidizing fracturing technology is only suitable for clastic gas layer with developed fracture and serious drilling fluid intrusion. |
