摘　　要：乌兹别克斯坦布哈拉-卡尔西地区油气资源丰富,开发有多个气田,由于该地区产层气体活跃,且含有H_(2)S和CO_(2)等有害气体,固井有效封固难度很大,尤其在投产后会逐渐出现环空带压现象。通过研究抗腐防窜水泥浆体系,并结合气井防气窜固井工艺技术,该地区的环空气窜现象得到有效缓解,成功保障各气田安全快速开发。The Bakhara-Karsi area of Uzbekistan is rich in oil and gas,and has developed many gas fields.Due to the active gas and contain H_(2)S and CO_(2),which is difficult for cementing,especially the annular pressure appears gradually after production of the gas well.Through the study of anti-corrosion and anti-channeling cement slurry,and the study of cementing technology for anti-gas channeling,which alleviated the annular pressure of gas well in this area effectively,and guaranteed developing of each gas field safely and rapidly.
