采用可限制压差并防止钻井液进入润滑系统的全橡胶储油囊,为轴承系统提供了良好的润滑保证。(联系人:王欢 手机) 三牙轮钻头 三牙轮钻头是石油钻井的重要工具.三牙轮钻头的抗磨性和较压性,可承受强的冲击载荷和来自牙轮钻头任意方向的压力; 三牙轮钻头 佳的高温性能、抗剪切安定性,可防止润滑脂在强剪切力和高温下流失; l 抗水性好,当密封圈损坏时,德驰三牙轮钻头润滑脂不会因水和钻井液侵入而造成分解和稀释; 三牙轮钻头良好的密封性,可防止各种介质侵入。 三牙轮钻头工作原理和种类: 人们为了寻找和开采石油和气,从地面向地下的油气层之间,使用三牙轮钻头钻凿出一个通道的过程称之为石油天气钻井,这些就是石油钻井需要了解的相关三牙轮钻头开凿的程序。 114. 115.116.117 低抗压强度高可钻性的及软地层,如粘土.泥岩.疏松砂岩. The 114-117 bits are used to drill low-compressive strength,soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear.On the softest bi types this hard facing completely covers the bit teeth 0.35---0.8 150---80 124.125.126.127 低抗压强度高可钻性的及软地层,如泥岩.石膏.盐岩.软页岩.软石灰岩 Soft formation with low compressive strength and high drillability. Such as sandstone, anhydrite, salt, shale, limestone. 0.3---0.9 180---80 134.135.136.137 低抗压强度高可钻性的及软至中软地层,如中软页岩.硬石膏.中软石灰岩.中软砂岩和有硬夹层的软地层 Soft to medium formations with low compressive strength, such as shale, anhydrite, sand and so on for soft formation 0.33--1.0 130----60 216.217 低抗压强度的软到中等地层,如中软页岩.中软石灰岩.中软砂岩.和有硬夹层的软地层 Soft to medium formations with low compressive strength, such as shale, anhydrite, sand and so on for soft formation 0.4---1.0 100---60
