PDC钻头操作扭矩比同WOB andlower地层条件，减轻肿胀钻扣小尺寸的问题。 双方的优势和PDC钻头，更多的三牙轮钻头thanfor强度和延展性牙轮钻头大编队，但也可以是appliedto PDC钻头难以处理的硬夹层和其他复合物的形成。

按照theapplicable行业分类

1. Geologicalexploration用PDC钻头

主要用于ingeological找矿勘探PDC钻头用于软到中硬岩石，somemanufacturers现在新的研究及新型复合板材canbe开发应用于十硬度的岩石。

2.煤田drillingusing PDC钻头

它主要用于incoal缝钻进去的挖掘。 一般来说比较柔软coalformations，PDC钻头已被广泛使用，例如锚位，三wingdrill等。

3.用PDC钻头oilexploration

主要是利用钻头用于oiland天然气钻探。 目前，油田PDC钻头是allPDC钻最高的成本内，要求最高。 PDC可以说thenobility。

PDC bit operating torque than the same WOB andlower strata conditions, reduce swelling drill buckle small size problems. Tricone rock bit of both the advantages and PDC drill bits, tricone bit more thanfor both strength and ductility are large formations, but also can be appliedto PDC bit difficult to deal with hard interlayer and other complex formation.

Accordance with theapplicable Industry Classification

1. Geologicalexploration with PDC drill

Mainly used ingeological prospecting exploration PDC drill for soft to medium-hard rock, somemanufacturers are now new research and development of new composite sheet canbe applied to ten hardness of rock.

2. Coalfield drillingusing PDC drill

It is mainly used incoal seam drilling on the excavation. Generally speaking relatively soft coalformations, PDC drill have been widely used, such as anchor bit, three-wingdrill and so on.

3. With PDC drill oilexploration

Mainly used in oiland gas drilling using the drill bit. At present, the oilfield PDC drill is allPDC drill inside the highest cost, requiring the highest. PDC can be said thenobility.
