摘要
针对靖边气田低渗无边底水气藏的地质特征和产水特征,结合靖边气田的开发工艺模式,在总结历年排水采气工艺试验效果的基础上,优选和优化了适合靖边气田的排水采气工艺,并提出了低压、低水气比气井复合排水采气工艺技术思路,为气田产水气井的中后期高效开发提供了技术支撑,对类似气藏排水采气工艺的选择和应用具有一定的借鉴意义。
According to geological and water-producing characteristics of low-permeability gas reservoirs without edge and bottom water in Jingbian gasfield,using their development experience,based on the test results of drainage gas recovery over the years,this paper optimizes the technology of drainage gas recovery,and puts forward a compound technology of drainage gas recovery for low-pressure and water-gas ratio gas wells.It provides technical support for highly efficient development of water-producing gas wells in its middle-late period,and can be used for reference in selecting and applying to similar gas reservoirs.
