Geopolymer composition and application in oilfield industry |
摘要 |
<p>The invention provides geopolymeric compositions, which have controllable thickening and setting times for a wide range of temperatures and a large range of geopolymer slurry densities. The geopolymer slurry compositions have good mixability and pumpability, whilst the set materials develop good compressive strength and permeability. The invention discloses a method for preparing geopolymer for oilfield cementing applications. The geopolymeric compositions according to the invention comprises a suspension comprising an aluminosilicate source, a metal silicate, an alkali activator, ligthweight or heavyweight fillers and a carrier fluid wherein the suspension of said geopolymeric composition is pumped in a well and allowed to set.</p> |
