Three cone bit manufacturers how to reduce the accident
Our drilling fluid performance must meet the requirements of high pressure jet drilling. In particular, to strictly control the sand content of drilling fluid, so as to avoid the hard particles in the high speed drilling fluid through the nozzle. Well narrow or underground complex, need long borehole reaming, cannot use the insert bit. Because the reaming the cone outer row of teeth by well wall great force, resulting in cone back cone and tooth palm tip wear, so bit necking, sealing ring early failure and premature bearing damage or even cone fracture fall accident in shaft. When the ground equipment damage, lack of power, pipeline thorn leakage, weight table is ineffective and drilling fluid performance does not meet the requirements or purifying device to achieve the expected results, should not human insert bit, in order to avoid downhole accidents caused economic losses.
