Structural features

In addition to the features of MD motor bit,MiniMD slim hole bit is also designed with special bearing & seal structure and lubrication system.MiniMD bit's cutter material and cutting structure are reasonably matches with rock properties of the formation and this eliminated the specific problems such as low drilling efficiency and cutter breakage and loss,etc.

MiniMD slim hole bit is the ideal choice for drilling slim hole sections in deep and ultra-deep well drilling applications.

The size range of MINI-MD series bit is from 5 3/4 to 6 1/2 inch,and IDAC varies from 437 to 647.

For example:6 1/2 MD 537

1.HIGH RELIABILITY AND LONG WORKING LIFE.

New type of lubrication system

Precisely designed and processed lubrication system and the use of new type of synthetic grease can improve balancing speed of the pressures inside and outside of the bearing  package and achieve better protection of the bearing and seal system of the bit.

2.IMPROVE BIT STABILITY,PREVENT BIT DIAMETER SHRINKAGE AND EXTEND THE BIT'S WORKING LIFE.

Inclined double-stable head O.D.

Improved stability of small size head O.D. and reduced bit vibration at the bottom hole are achieved by using specially designed inclined double-stable head body.Hydraulic system of the bit is also optimized on the basis of the special head O.D. design and as a result,bottom flow field under the condition of insuffcient hydraulic power in lower section in deep well is largely improved,removal of drilling cuttings is also improved and water out of the bit and other drilling tools by drilling cuttings is reduced and therefore,ROP is further improved.

3.OPTIONAL FEATURES:D,H,K,X,Y
