本文介绍了有机硅改性腐植酸泥浆处理剂的研制及其应用性能的实验结果。指出有机硅改性腐植酸降粘剂性能相当于铁铬盐。有机硅改性腐植酸防塌剂有较好的降滤失作用和一定的抑制页岩水化性能,能有效地改善钻井液的造壁性能。有机硅改性腐植酸系泥浆处理剂有满意的热稳定性和抗温性能,维护期长、配伍性好,是很有发展前景的新型泥浆处理剂体系。 In this paper, the development of organosilicon modified humic acid mud treatment agent and the experimental results of its application performance are introduced. Pointed out that silicone-modified humic acid viscosity reducer performance equivalent to iron chromium salts. Silicone-modified humic acid anti-collapse agent has a better fluid loss and inhibition of certain shale hydration performance, which can effectively improve the drilling fluid wall properties. Silicone modified humic acid mud treatment agent has satisfactory thermal stability and temperature resistance, long maintenance period, compatibility, is a promising new mud treatment agent system.
