为避免墨西哥湾(GOM)地区高度非固结地层因油藏枯竭而引起的压实损害,使用了泡沫水泥。泡沫水泥具有密度低、后期强度高的优点,除了起到层位封隔的作用,泡沫水泥水泥环能够减小套管变形、分离以及因应力作用引起的套管伸长的几率。泡沫水泥顶替钻井液效率高,防气窜,抗水泥环应力破裂,能够达到长久环空密封的目的。自1994年以来,配以一定的测井工具和隔离液体系。泡沫水泥在墨西哥湾地区应用了几百
To avoid compaction damage caused by depleted reservoirs in highly unconsolidated formations in the Gulf of Mexico (GOM) area, foam cement was used. Foam cement has the advantages of low density and high late strength. In addition to acting as a layer seal, the foam cement cement ring can reduce the casing deformation, separation and the probability of casing elongation caused by stress. Foam cement replacement drilling fluid efficiency, anti-gas channeling, anti-cement ring stress rupture, to achieve long-term annular seal. Since 1994, accompanied by a certain amount of logging tools and isolation fluid system. Foam cement has been used in the Gulf of Mexico for hundreds
