    金剛石復合片(PDC)錨桿鉆頭

    普通型(Normal kind

    普通金剛石復合片(PDC)錨桿鉆頭通常使用平面結構的金剛石復合片,有普通兩翼半片型和普通兩翼整片型兩種。該種鉆頭耐磨性好、抗沖擊性強,大大提高了施工效率,降低了勞動強度。常用規格Φ28~Φ42mm。

    Normal kind of PDC commonly used the PDC of planar structure, there are normal half-piece and whole piece two types. This kind of bit has good abrasion resistance and strong shock resistance, greatly improving the construction efficiency, reducing the labor intensity. Common specificationsΦ 28~ Φ 42mm.

    加強型(Forced kind

    加強型金剛石復合片(PDC)錨桿鉆頭通常使用球面結構的金剛石復合片。該種鉆頭穩定性好、成孔率高,其抗沖擊韌性強、不易崩邊,延長了鉆頭的使用壽命,主要適用于較硬的巖層。

    Forced kind PDC commonly used the PDC of Sphere structure. This kind of bit has a perfect stability in penetration and strong shock resistance, and it is not easy to be collapsed, so that can prolong the service life of the bit. Mainly used in hard rock.

    PDC錨桿鉆頭所用金剛石復合片(PDC

    金剛石復合片(PDC)是由金剛石聚晶和硬質合金襯底,采用超高壓高溫技術復合而成的超硬復合材料制品。金剛石復合片具有極高的耐磨性、優異的耐熱性和抗沖擊性能。主要用于石油鉆井、煤礦開采、地質鉆探等工具刃部。

    PDC is composed of polycrystalline diamond and cemented carbide substrate, which is a super hard composite product adopting ultra high pressure and high temperature technology. PDC has high wear resistance, good heat resistance and strong shock resistance. It is mainly used for the edge of tools applied in the field of petroleum drilling, coal mining and geological drilling.

    對于鉆進軟—中硬地層,我單位采用平面結構的金剛石復合片,其特點是鉆進速度快,但是抗沖擊性能有一定局限性。對于較硬的復雜巖層,我單位采用球面結構的金剛石復合片,其具有較高的抗沖擊性能,從而提高了鉆進工具的使用壽命,但其鉆進速度較慢于平面結構的金剛石復合片工具。

    For drilling in soft-medium hard formation, our company use the Normal PDC.,which has the character of fast drilling speed, but impact resistance is limited. For better hard rock, our company adopt Forced PDC. Its high impact resistance prolongs the service life of drilling tools, but the drilling speed will be slow than the normal kind.
