中文摘要：
环空气窜是固井后气体窜至井口或另一地层的现象,气窜发生后会直接影响水泥石胶结强度,严重时可造成固井后井喷事故。硫铝酸盐封堵效果以物理模拟实验的结果表明：裂缝尺寸大小对抗水窜、抗汽窜效果影响较小,温度升高、胶结时间短使界面胶结强度降低,在现场施工中应充分考虑这些因素对封堵效果的影响。
英文摘要：
It is called annulus space gas breakthrough that formation fluid formation after well cemented. If annulus space gas breakthrough has emerged result in well blowouting. Conclusion of sulphoaluminate blocking sealing that fracture width of cementation does not affect the effectiveness of short of cementing time can lead interface cementing strength fell, all should consider. flowthroughs to well head or the other , the cementing strength will fall, even effect physical analog experiment show sealed off. In addition temperature rise and the factors above when practising in field be
