摘　　要：华北油田冀中探区潜山油气藏井底温度高达170℃,注水泥作业难度大,部分天然气井或含气油井由于水泥与地层界面胶结质量较差,发生层间互窜现象,造成能源流失和油气井产量下降。超细防气窜水泥浆体系具有防气窜、低密度、低失水、抗水泥石高温强度退化等优点,适用于超深油气井注水泥作业。在现场应用中,该体系成功地完成了多次固井注水泥作业和打塞注水泥作业,解决了超深天然气井固井技术难题。The bottom hole temperature as high as170℃ in Qianshan reservoir of Huabei oilfield complicates cementing operation. Bonding between cement and rock is bad, and influx often occurs. An anti-gas channeling ultra-fine cement including micro silicon and filtrate controller is used. This cement slurry provides good properties such as low density, low filtration, gas channeling prevention and stable compres-sive strength at high temperature. This slurry system made several cementing and plugging operation successful.
