PUMPABLE GEOPOLYMER FORMULATION FOR OILFIELD APPLICATION |
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 made of an aluminosilicate source, a carrier fluid, an activator taken from the list constituted by: a metal silicate, a metal aluminate, an alkali activator, or a combination thereof, and the suspension is a pumpable composition in oilfield industry and the suspension is able to set under well downhole conditions.</p> |
