第463期:钻杆常用专用管螺纹和钻杆管材的类型及规格
第463期:钻杆常用专用管螺纹和钻杆管材的类型及规格钻具接头螺纹钻具接头螺纹用于如钻铤、钻杆、钻具稳定器及转换接头等钻井工具及钻柱构件的连接。
目前生产和检验依据的标准主要是API SPEC 7。
API SPEC 7称钻具接头螺纹为“旋转台肩连接”,是连接钻柱构件最主要的机械机构。
这种带锥螺纹具有通过轴向位移来补偿连结部分直径误差的特点,因此互换性程度高、结合紧密和装拆容易。
其技术特点为英制锥管螺纹、有台肩连接、三角形螺纹,在管材连接中应用极为广泛。
其主要螺纹型式如表1所示。
表1:钻具接头螺纹类型序号螺纹型式英文写法螺纹牙型规格与种类1 数字型(NC)Numberstyle connection theads V-0.038R NC23-NC77共计13种2 内平型(IF) Internal-flush style connection threads V-0.065 23/8in-51/2in共计6种3 贯眼型(FH) Full-hole style connection threads V-0.065V-0.050V-0.040 31/2in-65/8in共计5种4 正规型(REG)Regularstyle connection threads V-0.050V-0.040 23/8in-85/8in共计8种1. 内平型螺纹该型钻具接头螺纹连接外加厚或内外加厚钻杆,形成钻杆接头内径、管体加厚内径与管体内径相等或近似的通径。
所有规格螺纹均采用V-0.065平顶平底三角形牙型,这种牙型为平牙底,牙顶较宽度为0.065英寸(1.651mm)。
除51/2IF外,其它规格螺纹的因结构尺寸与相应的数字型螺纹完全相同,故具有互换性。
该型螺纹因其牙型结构易导致应力集中,其中包括41/2IF和4IF,它们就是曾经在我油田被大量使用的410、411和4A10、4A11,取而代之的是NC50和NC46数字型螺纹。
2. 贯眼型螺纹该型钻杆接头螺纹连接内外加厚钻杆,形成钻杆接头内径和加厚端内径相等,而均小于钻杆管体内径的通径。

GB/T 9253.1-1999石油钻杆接头螺纹代替GB/T 9253.1-1988 Threads on rotary shouldered connections for petroleum industry1 范围本标准规定了数字型(NC)、内平型(LF)、贯眼型(FH)和正规型(REG)石油钻杆接头螺纹(即带台肩连接螺纹,简称螺纹)的牙型、基本尺寸、公差和标记。
由于数字型螺纹的牙型和锥度较内平型、贯眼型和正规型螺纹更合理。
在新产品设计时推荐选用数字型螺纹。
本标准适用于井下工具和钻柱结构件的连接。
