摘要(Abstract)：

泡沫排水采气固体消泡剂存在结构松散、效果较差、成本高等缺点,严重制约其大规模推广应用。通过优选二甲基硅油做主剂,利用它的消泡活性高、无生理毒性、制备过程中转化率高等特点,充分提升消泡剂基础体系性能,并大幅降低成本;同时,新合成了一种疏水型的二氧化硅纳米颗粒做增效剂,并按一定比例与主剂复配,形成了消泡剂的有效成分,借助疏水型纳米颗粒的针尖和渗透作用,充分发挥二者的协同作用,可减小消泡过程中建立油桥的阻力,大幅提高有效成分的消泡能力;然后,优选出一种对消泡剂有效成分性能无伤害且成型效果好、低成本的固化剂,采用熔融的方式与有效成分充分融合并冷却成型,最终形成了一种新型的纳米高效固体消泡剂。实验对比测试结果和气田178口井实际应用表明,该新型纳米高效固体消泡剂较常规固体消泡剂的消泡、抑泡能力分别提升9.1倍和13.7倍,有效时间增加14.2%、日消耗量降低13.95%、综合成本降低63.12%,效果非常显著。
The solid defoamers of the water discharge and gas production by the foams are characterized by loose structure, poor effect, high cost and the other disadvantages, thus the large-scale popularization and application are seriously restricted. By means of optimizing the dimethyl silicone oil regarding as the main agent and taking full use of its advantages: high activity of antifoaming, non-physiological-toxicity, high-transformation ratio and so on, the basic systematical performances of the antifoamer were completely enhanced, and moreover the cost was reduced to a great deal;at the same time, a new hydrophobic-type silica nano-particle synergist was generated, and furthermore by combining with the main agent by a certain proportion, the efficient compositions of the defoamer were formed, with the help of the penetrating and permeating actions, the synergy of the two actions stated above was fully made, thus the resistance of establishing the oil bridge in the process of the defoaming was reduced, the defoaming capacity of the effective composition was greatly enhanced; and then, the curing agent with no damage, good forming and low cost to the effective composition of the defoamer was optimized, with the help of melting, the effective composition was melted and cooled to form, finally the new nano and high-efficiency solid defoamer was generated. The comparisons of the experimental tested results and actual application in 178 gas wells show that compared with the conventional solid defoamers, the defoaming and anti-foaming capacities of the new nano and high-efficiency are enhanced 8 times and 13.6 times, the effective time is prolonged by 14.2%, the daily consumption is reduced by 13.95%, the comprehensive cost is reduced by 63.12%, in a word, the effects are much more obvious.
