The Effect of Drilling Mud Flow on the Lateral and Axial Vibrations of Drill String

ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 5, 2010
In this research, the effects of drilling mud flow and WOB force on the lateral vibration of drill string are investigated. To this goal, the kinetic and potential energy of drill string for axial and lateral vibrations are written in an integral equation.

The Study on Vibration of Drill String of ERW

2008 International Conference on Computer Science and Software Engineering, 2008
During exploitation of extended reach well (ERW) drilling engineer, the problem of drill string failure is very serious; drill string vibrations are main reasons. In this paper drill string of extended reach well of different part is object being studied. The models about various vibrations are set up. Modal vibrations of drill string are studied.

Nonlinear Stochastic Drill-String Vibrations

Journal of Vibration and Acoustics, 2002
Lateral vibrations of drill-strings used in oil well operations are considered. A finite elements based discretization procedure leads to a nonlinear dynamic system which is used to represent the drill-string inertia and stiffness characteristics, as well as the elasticity of the wall of the well.

An Experimental Study of Drill-String Vibration

Journal of Engineering for Industry, 1960
This paper describes equipment which has been developed for the measurement of axial force, torque, and axial and rotational motions at the top of a drill string. Measurements made in two wells with this equipment represent the first time these quantities have been recorded during drilling.

Stick-Slip Vibration of Drill Strings

Journal of Engineering for Industry, 1991
The stick-slip vibration is introduced as a new mechanism to explain the large amplitude torsional oscillation of the drill strings in oil and gas well drillings. A record of field data is identified and simulated according to the new mechanism. The analytical results derived from the numerical simulation agree with the field data with 95.6 percent ...

Research and Analysis of Drilling String Vibration Signals

2020 IEEE International Conference on Mechatronics and Automation (ICMA), 2020
Drilling tools are the main components of the drilling system, including drill bits and drill rods. During the drilling process, due to the collision between the drill bit and different formations, the drill string often vibrates, which causes damage to the drill bit and has a serious negative impact on drilling.

The Use of Aluminum Drill Pipe for Damping Drill String Vibrations

SPE Norway One Day Seminar, 2018
Abstract Drill string vibrations are a significant concern during drilling operations, and are a common cause of downhole tool failures and decreases in drilling efficiency. Drill string vibrations are typically categorized in three ways: axial (the drill string is vibrating along the axis of drilling), lateral (the drill string is ...

Longitudinal Vibrations of a Drill String

The Journal of the Acoustical Society of America, 1965
When drilling an oil well with a rotary drill, the penetration rate often can be substantially increased by superimposing a vibratory motion on the rotating bit. In order to evaluate drilling methods that would include both rotary and vibratory action, a study has been made on the vibrational characteristics of long drill string. The resonant frequency

Drill String Vibration: How to Identify and Suppress

Proceedings of Latin American and Caribbean Petroleum Engineering Conference, 1997
Abstract Drill string vibrations can diminish the life of the pipe by accelerating the process of fatigue. Also excessive vibration can cause pipe failure, wash-outs and decrease in the penetration rate. This work describes the first experience in Brazil on identification and suppression of vibrations of the pipe ...
