由于我国石油化工的发展,二十年前价格高昂的Гинпа(英文名CYPAN),已被用于钻井泥浆,这就是睛纶下脚料,其中主要成份为聚丙烯睛。是一种优良的降失水剂,用于泥浆可以避免多种井下复杂问题。由于价廉易得,效果显著,配制简单,已在石油钻井中被陆续采用。毫无疑问,聚丙烯睛也将适用于地质岩心钻孔。这是因为:1.聚丙烯睛有良好的降失水能力,能保护井壁,抑制易塌地层。如表1。
Due to the development of petrochemical industry in our country, the expensive Гинпа (English name CYPAN) twenty years ago has been used in drilling mud, which is the crownfelt waste, the main component of which is polypropylene eye. Is an excellent fluid loss additive for mud that avoids multiple downhole complications. Due to its low price, obvious effect and simple preparation, it has been adopted one after another in oil drilling. There is no doubt that polypropylene eye will also be suitable for drilling in geological cores. This is because: 1. Polypropylene eyes have a good ability to reduce water loss, to protect the borehole wall, inhibit the formation of easily collapsed. Table 1.
