SKP是我公司专门针对深井、超深井、钻遇大段盐膏层等复杂井所研制出的一种新型抗高温、抗盐、抗钙强降滤失剂。该产品是由由苯酚、甲醛、磺化剂等各种原料在一定的条件下经多次聚合和磺化而成，为粉末状阴离子水溶性聚电解质。该剂降低高温高压滤失量效果好，抗高温达180℃以上，抗盐至饱和，能有效改善泥饼质量，降低泥饼磨擦系数，对于巩固井壁，防塌、防卡具有重要作用。建议加量1-3%,适合应用于各种钻井液。
一、产品特性
1、 抗温效果好,抗温可达180℃，在该温度下具有较强的稳定性，且不易降解。
2、 抗盐、抗钙镁能力强，抗盐可达饱和，抗钙可达3000ppm，抗镁可达2000ppm。
3、 加量小，降滤失效果好，对钻井液其它性能影响小，能有效降低成本，特别适合用于钻大段高压盐膏层所使用的高密度钻井液体系中。
4、 配伍性好，能与各种处理剂配合，适用于各种水基钻井液体系，且现场应用工艺简单，维护处理方便。

SKP High Temperature and Salt Resistant Calcium Filtrate Reducer
Product Details
SKP is a new type of high temperature resistant, salt resistant and calcium resistant fluid loss reducer specially developed by our company for deep wells, ultra deep wells, drilling large salt gypsum layers and other complex wells. The product is made of phenol, formaldehyde, sulfonating agent and other raw materials by multiple polymerization and sulfonation under certain conditions. It is a powdered anionic water-soluble polyelectrolyte. It can effectively improve the quality of mud cake, reduce the friction coefficient of mud cake, and play an important role in consolidating wellbore, preventing collapse and sticking. The recommended dosage is 1-3%, which is suitable for various drilling fluids.
Product Features
1. The temperature resistance is up to 180 ℃. It has strong stability at this temperature and is not easy to degrade.
2. Salt resistance, calcium and magnesium resistance are strong, salt resistance can reach saturation, calcium resistance can reach 3000ppm, magnesium resistance can reach 2000ppm.
3. It is especially suitable for high density drilling fluid system used for drilling large section of high pressure salt gypsum formation.
4. It is suitable for all kinds of water-based drilling fluid systems, and its field application process is simple, maintenance and treatment is convenient.
