摘　　要：针对红台气田储层"四低"(低丰度、低孔隙压力、低孔隙度、低渗透率)和"二强"(水敏伤害强、非均质性较强)的特点,以及单层压后吐砂、产量低、稳产期短的现状,通过压裂技术创新和进步,形成了一套适合该气田储层特征的压裂改造技术体系,现场应用效果显著。其中用于气井的压裂投产一体化技术、防支撑剂回流技术,为形成日产50×104m3天然气稳产能力提供了有力的技术保障,为类似气田的开发提供了成功经验。To the features of 'four low'(low abundance,low porous pressure, low porosity and low permeability) and 'two high'(high water-sensitive damage,high heterogeneity) of Hongtai natural gas reservoir,and actuality of producing sand at postfrac,low production and short constant flow rate period,through technical innovation and progress of fracture technique,a set of technique system has been come into true and the result in field application is obvious.The integrated tech of fracture and putting in to production among them,preventing back flow against proppant is prominent at domestic to supply a powerful technical guarantee for forming a stable production volume of natural gas at 50 million m3 per day which provides a successful experience for exploiting similar gas field.
