GLYCOL 聚合醇抑制剂 Polymeric Alcohol Inhibitor
简介Introduction
GLYCOL聚合醇抑制剂是一种无荧光、环保、显著改善钻井液热稳定性的防塌润滑抑制剂。在环境温度大于浊点温度时，产品形成液态微粒状的乳液，参与泥饼形成，封堵泥饼滤失通道，降低体系滤失，稳定井壁，抑制防塌性能优良；同时其表面活性特征，可显著改善钻井液的高温稳定性。
GLYCOL Polymeric Alcohol Inhibitor is a non-fluorescent, environmentally friendly, and effective inhibitor for preventing collapse and improving the thermal stability of drilling fluid. When the ambient temperature exceeds the cloud point temperature, the product forms liquid crystailine microemulsions that participates in the formation of a mud cake. It blocks the filtration loss channels of the mud cake, reduces the filtration loss of the system, stabilizes the wellb, and has excellent inhibitive and anti-collapse properties. Meanwhile, its surfactant characteristics can significantly enhance the high-temperature stability of the drilling fluid.
