摘要

Nano su00cdlica for application in folders cimentantes of low density in pou00c7os petroleum. The nano silica is present as an additive spreader pair application in systems of Portland cement pastes with low specific weight.This material consists of a uniform dispersion of colloidal particles of silicon dioxide in water, to be added to the system of folders with high water cement factor, substantially reduces the formation of free water and considerably improves the resistance values M Ecu00e2nica pastes cured due to the high surface area presented by the nano particles.These properties characterize the application of nano silica as a potential additive for use in cementing operations in oil wells. The pastes were formulated and tested in accordance with the rules of API RP 10B and spec 10A (Amercan Petroleum Institute).
