Defoaming agent for oil well cement and preparation method thereof
The present invention relates to the technical field of oil well cement, and provides an oil well cement defoamer and a preparation method thereof, the oil well cement defoamer comprises the following raw materials by weight: 30-40 parts of silicone oil, 8-10 parts of modified silica, 5-10 parts of an emulsifier, 0.5-1 part of a thickener, and 80-100 parts of water, and the modified silica is obtained by modifying silica with a silane coupling agent KH-550 and 2, 4-diaminoanisole. According to the technical scheme, the problems that in the prior art, an organic silicon defoaming agent is poor in defoaming performance, and the compressive strength is low when the organic silicon defoaming agent is applied to oil well cement are solved.
本发明涉及油井水泥技术领域，提出了一种油井水泥用消泡剂及其制备方法，包括以下重量份组分的原料：30~40份硅油、8~10份改性二氧化硅、5~10份乳化剂、0.5~1份增稠剂、80~100份水，所述改性二氧化硅为二氧化硅经硅烷偶联剂KH‑550和2,4‑二氨基苯甲醚改性得到。通过上述技术方案，解决了现有技术中有机硅消泡剂的消泡性能差以及应用在油井水泥中抗压强度低的问题。
