| 摘要 |
The present invention provides a well treatment composition comprising a surfactant comprising a substituted ethoxylated phenol having at least one substituent, 1 to 14 moles of ethylene oxide, and the substituent being an alkyl, alkene, or alkyne with a carbon chain length in the range of 4 to 25, wherein the substituted ethoxylated phenol is selected from the group consisting of: ortho-, para-, or meta- substituted ethoxylated phenol; cardanol ethoxylate; derivatives thereof; and combinations of any of the foregoing. Preferably, the surfactant comprises cardanol ethoxylate, a substituted cardanol ethoxylate, and derivatives thereof. According to another embodiment, a method of cementing in a subterranean formation comprises: introducing a cement composition into the subterranean formation, wherein the cement composition comprises: (A) cement; (B) water; and (c) the surfactant; and allowing the cement composition to set. |
