摘要：
Disclosed herein are defoamers comprising ethylene glycol, a defoaming hydrocarbon base fluid, and a non-ionic surfactant wherein the hydrocarbon base fluid comprises an internal olefin or a straight-chain n-alcohol, and wherein the non-ionic surfactant is present in the defoamer in an amount in the range of from about 1% to about 10% by weight of the defoamer. Also disclosed herein are cement compositions comprising water, hydraulic cement, and a defoamer, wherein the defoamer comprises ethylene glycol, a non-ionic surfactant, and a defoaming hydrocarbon base fluid wherein the hydrocarbon base fluid comprises an internal olefin or a straight-chain n-alcohol, and wherein the non-ionic surfactant is present in the defoamer in an amount in the range of from about 1% to about 10% by weight of the defoamer.
