摘　　要：徐深气田水体分布范围较大,火山岩气藏底部普遍含水。由于储层多为裂缝沟通,一旦见水极易造成水侵或水窜,部分气井试气阶段即出水。随着徐深气田深入开发,所有气井都会面临气-水同产问题,水不仅影响气井产能,严重时会导致井底积液,甚至气井水淹停产。通过分析徐深气田产水机理和具体出水类型,对照国内外常规排水采气工艺适用界限进行技术及经济适用性评价,结合典型井生产情况,提出了适合大庆火山岩气藏开发初期的排水工艺为泡排、优选管柱,为大庆徐深气田火山岩气藏的高效开发提供指导。Xushen gasfield has a larger distribution range of water body.Water exists generally at the bottom of volcanic gas reservoir.As many fractures develop in the reservoir,water invasion or breakthrough is easy to appear,especially in some wells during well testing.Along with further development of Xushen gasfield,the problem of producing gas and water appears simultaneously in all wells.Water can not only affect the productivity,but also induce the bottomhole accumulation.Furthermore,well will be shut-in due to watering out.According to the mechanism and type of producing water,evaluating the technical and economic adaptability through comparing the application ranges of conventional drainage gas recovery technologies at home and abroad,integrating the production status of typical wells,this paper suggests that the suitable drainage technologies for the initial development of volcanic gas reservoir in Daqing oilfield are foam drainage and pipe string optimization.That provides a guideline for efficient development of the gasfield.
