Experimental Device of Drilling String Dynamics in Horizontal Well and Its Application
(0) According to the principle of similitude,a simulation experimental device for investigating drilling string dynamics in horizontal well was designed and set up.The rotary speed,WOB,drilling string lateral displacement,bottom hole WOB fluctuations and lateral force of the bit,etc.can be measured under different WOB and rotary speed by the experimental device; Some debugging experiments have been done by means of the device under different weights on bit and rotary speeds.The simulated experiment has many advantages comparing to the actual experiment,such as less operators,less times and moneys.It is easy to operate,the drilling string movement can be visually observed and all of the experimental results can be used to the actual drilling.
