    Feasibility study on roller-cone bit wear detection .

    In this study, the dynamics of roller-cone bit axial vibration were modeled to quantitatively evaluate bit-tooth wear. The model includes the kinematics of roller-cone bit motion and a model for bit-tooth/rock interaction that considers the detailed geometry of a worn tooth. By sequentially solving the equation of motion with increments of cone rotation angles, the time history of axial bit ...

    Responding to the Challenge for More Power

    applications including drill bits, mud motors and liner hanger bearings. Introduction Mud pumps, used for oil and gas drilling operations, get their name from the specially prepared fluid (mud) that is pumped through the drill pipe to evacuate cuttings from the hole, as well as to cool and lubricate the drill bit. These are generally low-speed, high-displacement reciprocating pumps and can be ...

    How to choose correct turning insert

    The relationship between nose radius and depth of cut affects vibration tendencies. The radial forces that push the insert away from the cutting surface become more axial as the depth of cut increases. It is preferable to have more axial forces than radial. High radial forces can have a negative effect on the cutting action, which can lead to ...

    Drilling mechanics and performance - IADC

    teeth of a more aggressive roller cone bit are aligned to stay on bottom and engaged for a greater distance in the rock, so they remove more rock volume per minute. The expected responses to WOB are shown in Figures DP-2a, -2b and -2c. If the bit is efficient, a plot of ROP vs WOB will form a straight line, regardless of rock strength, bit cut-ters and design, or RPM. The straight line is ...

    US7621343B2 - Steerable drilling system and .

    Roller cone bits also may introduce more of a bit bounce action since roller cone bits rely on greater WOB to drill than PDC. A roller cone bit, like a PDC bit, benefits from stiff and true piloting of the bit itself to minimize the non-constructive behaviors. The comments on bit face to bend length and on the placement of stabilizers are thus also generally applicable to roller cone bits. A ...

    01.12.2013· Vibrations are unavoidable since drilling is the destructive process of cutting rock either by chipping (using drag/PDC bits) or crushing (using roller cone bits) action. Field observations have shown difference in vibration measurements on surface and in downhole which means BHA undergoes severe vibrations.

    Spatial Resolution - an overview | ScienceDirect .

    Spatial resolution corresponds to the elementary size of the ground surface measured by the different instruments of an embedded sensor. At a particular altitude, an observer (human eye or electronic detector) perceives the ground according to a cone of visibility depicted in Figure 2.10.In this figure, it is clear that the surface area being observed depends strongly on the altitude of the ...

    FAULHABER DC motor – revolutionarily good

    When Wilhelm Röntgen discovered and investigated the X-ray in the late 19th century, he was one of the few pioneers in the field who routinely used protective lead shields. He may not have known the precise reasons why, but he suspected that this kind of radiation was not good for human health – and his suspicions were well founded.
