Prevention of latex inversion in saltwater cement compositions for use in subterranean formations and associated compositions
摘要：
The prevention of latex inversion in saltwater cement compositions for use in subterranean formations by inclusion of a combination of latex stabilizers and associated methods of cementing. Saltwater cement compositions comprising saltwater, a cement, a latex, a first latex stabilizer comprising a surfactant having the formula: R—O—(OCH2CH2)mXM wherein R is an alkyl group having in the range of from about 10 carbons to about 20 carbons, m is an integer in the range of from about 10 to about 40, X is OSO3 or SO3, and M is a compatible cation, and a second latex stabilizer comprising an alcohol ether sulfate having the formula: R1—O—(OCH2CH2)nOSO3M wherein R1 is an alkyl group having in the range of from about 4 carbons to about 12 carbons, n is an integer in the range of from about 1 to about 10, and M is a compatible cation.
