位类型

在当今市场上有两种类型的钻井钻头，牙轮钻头和PDC钻头的。

位名称

铣齿牙轮牙轮钻头水打井

讲标出台

有迹象表明，已经用于钻油井几十年来一个正常锥体3位。 有许多类型的从软地层/低抗压强度到极硬和磨料形成的使用，从滚子轴承的空气冷却到密封滚子轴承，并密封摩擦轴承与保径。 如需订购，你必须指定IDAC，三位数没有。 拳头位指定的形成，第二个数字位的类型和第三位数字被分配以密封类型和位的关闭过程的尺寸需要

详细信息

有两类三牙轮钻头。 用于软地层极其坚硬，研磨性地层这通常是软使用中形成和碳化钨插入（TCI）铣齿钻头

特征

Bit type

In the market today there are two types of Drilling Bits, Roller cone and PDC Bits.

Bit name

milled tooth tricone Roller Cone Bits for water well drilling

Brife introduction

There are a normal three cone Bits that have been used for drilling Oil wells for decades. There are many types to use from soft formation / low compressive strength to extremely hard and abrasive formation, from roller bearing air cooled to sealed roller bearing, and to sealed friction bearing with gage protection. For ordering you must specify IDAC, three digit no. the fist digit specify formation, second digit the type of Bit and the third digit is allocated to seal type and off course the size of Bit required

Details

There are two categories of three cone Bits. Mill tooth Bits which is normally use for soft to medium formation and Tungsten Carbide Insert (TCI) used for soft formation to extremely hard and abrasive formation
