As the exploitation of oil and gas field becomes more difficulty nowadays, severe casing deformation may occur if anti-extrusion strength decreases to a certain degree this brings large economic loss safety problems. an annular sheath between formation, creep well cement paste is one most important factors in deciding abnormal wellbore integrity. To figure out mechanism on how reduce value past...

One of the effective ways to increase durability building products and structures operating under influence aggressive media is using sulfur binders manufacture concretes. It shown that chemical resistance concretes a greater extent depends on matrix composition. was found introduction modified additives increases their resistance. With optimal content additives, water composites from 2.3 3.2 t...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...
