Product Description

Category:
Three-cone bit is an important tool for oil drilling. Its working performance will directly affect drilling quality, drilling efficiency and drilling cost f1.The design of three-cone bit is mostly based on practical experience and combined with the method of trial and error to carry out repeated design and calculation. As a result, the design accuracy is low and the cycle is long, so it is difficult to improve the design quality. Moreover, only one bit can be designed in each calculation, resulting in low efficiency.

Matters needing attention
A. Don't break the cone bit gear when connecting and unloading the bit.
B. Keep the mud clean to prevent the bit from blocking the water hole, which may affect the use of the bit.
C. Control the speed of drilling down to prevent sudden resistance, so that the roller bit can play a better role.
D. keep the water on the two pumps intact.
E. Keep the bottom of the well clean and free of falling objects; install mud scraper or cover the wellhead with steel plate in both lifting and drilling; check the clamp tooth safety pin and wellhead tools frequently to prevent falling objects from the wellhead.
F. Pay attention to the drill bit to prevent slipping and stamping.
G. Timely adjust drilling parameters in case of drilling bit or jumping.
H. Drill the cone bit to the bottom, circulate for about 10 minutes, drill 0.5 meters with 1-2 tons, and slowly pressurize to drill with 6-tons.The drill is sent evenly to prevent the tooth from being damaged suddenly. The drilling pressure is generally less than 10 tons.When the drilling is slow, to analyze, if because of the interlayer to be patient, do not blindly add drilling pressure.
Three-cone bit is one of the most widely used drilling bits, which has the characteristics of wide formation adaptation and high rop.Three-cone bit is composed of cutting structure, bearing structure, locking element, oil storage and sealing device, nozzle device and more than 20 parts.Classification of three cone bits
1. Bearing type: rolling bearing and sliding bearing
2. Seal type: rubber seal and metal seal
3, according to the fixed way of teeth are divided into: insert teeth (carbide teeth) three cone bit and milling teeth (steel teeth) three cone bit
