操作金剛石鉆進(jìn)的技術(shù)要求 (1)下鉆時(shí),操作人員應配好機上余尺,掌握孔內情況,鉆頭通過(guò)擰管機、套管口或換徑處、活石處,應放慢下降速度。下鉆遇阻,不應猛沖硬鐓,可用管鉗慢慢回轉鉆具,無(wú)效時(shí)應立即提鉆,采用其他方法處理。 (2)每次下鉆,不得將鉆具直接下到孔底。距孔底約1m時(shí),應接上水龍頭開(kāi)泵送水,等孔口返水后,輕壓慢轉掃孔到底,正常后可按要求參數鉆進(jìn)。 (3)配好機上余尺,在回次鉆進(jìn)中,不準中途將鉆具提離孔底接鉆桿。鉆進(jìn) (1)鉆進(jìn)時(shí)要嚴格遵守操作規程,合理選擇鉆壓、轉速及泵量。鉆進(jìn)正常后, 意改變鉆進(jìn)參數

瑞龍鉆具金剛石PDC燒結體鉆頭，三翼內凹型和平頂支柱型的特點(diǎn)和優(yōu)缺點(diǎn)？

金剛石PDC燒結體鉆頭的共同點(diǎn)：具有適應高研磨性巖層的共同特點(diǎn)，鉆頭體強度高，通常配以高等級復合片制造而成，具有耐磨性能好的特點(diǎn)；平頂燒結鉆頭，相對內凹型相對平頂型來(lái)進(jìn)尺速度快，在斷裂帶等復雜條件下鉆孔容易發(fā)生卡鉆導致鉆具損壞現象。

PDC鉆頭金剛石復合片鉆頭的特點(diǎn)——瑞龍鉆具

金剛石復合片（PDC）是在高溫條件下，由人造金剛石與硬質(zhì)合金一次性合成的特殊超硬材料，它不但具有金剛石硬度高、耐磨等優(yōu)點(diǎn)，同時(shí)還具備了硬質(zhì)合金抗沖擊性強、出刃大等特點(diǎn)，用它做鉆頭的刀翼可大大提高鉆頭的工作效率，是鉆進(jìn)中硬巖層和堅硬巖層的理想鉆頭。

金剛石復合片鉆頭的強度區分——瑞龍鉆具

金剛石復合片鉆頭的強度主要是由金剛石復合片的強度決定的，當前，金剛石復合片鉆頭在強度上主要分為普通型、加強型、高強型三種；金剛石復合片主要分為1304和1308兩種，1304和1308指的是復合片的直徑和厚度，我們采用的基本區分為：普通型、加強型和高強型；其中普通型為1304平面復合片，加強型為1304球面復合片和1308平面復合片，高強型為1308球面復合片。
