GLYCOL 聚合醇抑制劑 Polymeric Alcohol Inhibitor
簡介Introduction
GLYCOL聚合醇抑制劑是一種無熒光、環(huán)保、顯著改善鉆井液熱穩(wěn)定性的防塌潤滑抑制劑。在環(huán)境溫度大于濁點溫度時，產(chǎn)品形成液態(tài)微粒狀的乳液，參與泥餅形成，封堵泥餅濾失通道，降低體系濾失，穩(wěn)定井壁，抑制防塌性能優(yōu)良；同時其表面活性特征，可顯著改善鉆井液的高溫穩(wěn)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.
