钻头现场使用

FIELD USE OF DRILL BITS

◆　钻头搬运过程中注意防碰，使用前检查切削齿是否损坏，水嘴是否堵塞。

◆　下钻时，钻头上扣要使用专业的上卸扣器，并控制下放速度。下放途中应接上方钻杆，开泵循环1-2次，避免堵水嘴。尽量避免用钻头划眼。若必须划眼，用大排量，缓慢转动钻头，且时间不超过2小时。

◆　钻头下到井底后，提高井底0 5米以上，循环泥浆并缓慢转动钻具，确保井底清洁。在钻头接触底部后，以低钻速和低钻压进行井底造型0.5-1米。

◆　钻压试求法选定钻井参数，以达到更快机械钻速，但不得超过出厂推荐使用参数。可根据地层变化情况，适当调整参数，以获得更好机械钻速。

◆　钻井时坚持使用钻杆滤清器，防止塞水嘴。按照选定的钻压和钻速进行正常钻进，送钻要均匀。钻遇硬夹层时，可适当降低钻压，待钻穿后钻压再恢复正常。

◆　Avoid collision during bit handling, check whether the cutting tooth is damaged before use, and whether the faucet is blocked or not.

◆ Use professional upper shackle on drill bit while drilling and control the running speed Apply the drill pipe in the lower part of the way and turn the pump round l-2 times to avoid clogging the faucet.Try to avoid using a bit to reaming. If necessary rotate the bit slowly with a large displacement, and the time is no more than 2 hours.   

◆ After the drill is lowered to the bottom of the well, it is removed more than 0 5 meters above the bottom. The mud is recycled and the driHing tool is slowly rotated to ensure the bottom of the well is clean. After the drill touches bottom, shape the bottom 0.5-1 meters with low drilling speed and low drilling pressure.

◆ The drilling parameters should be selected by the optimum bit pressure test method to achieve the fastest drilling rate, but not exceed the recommended plant parameters.Tha parameters can be adjusted according to the change of stratum to obtain the optimum drilling rate.

◆ Insist on using drill pipe filter when drilling to prevent plug.Perform normal drilling according to selected drilling bit pressure and drilling speed, and drill evenly.When drilling the hard interlayer, the drilling pressure can be reduced properly,and the drilling pressure will be resumed after drilling.
