为满足大位移复杂工艺井等钻探和环保的需要,研制开发了新型的水基润滑剂,采用一种水溶性聚醚对硅油进行改性,在保持硅油润滑性的同时改善其水溶性。同时添加一种具有较小表面张力、极强抗盐抗温能力的新型含氟表面活性剂,使水基润滑剂的润滑性、高温稳定性和抗污染能力得到提高,满足了现场使用的需要。该产品与常规处理剂配伍性良好;合成工艺简单,具有推广应用价值。现场应用效果良好。
In order to meet the needs of drilling and environmental protection such as large-displacement complex process wells, a new type of water-based lubricant has been developed. A water-soluble polyether is used to modify the silicone oil to improve the lubricity of the silicone oil while improving its water solubility. At the same time, adding a new kind of fluorine-containing surfactant with less surface tension and strong resistance to salt and heat, the lubricity, high temperature stability and anti-pollution ability of water-based lubricant are improved, which meets the needs of field use . The product is compatible with the conventional treatment agent; synthetic process is simple, with the promotion and application value. Field application of good results.
