Key technologies for directional well drilling in .

01.12.2018· As to the main reason for drill pipe sticking, the increase of rheological property after mudstone hydration leads to tight holes, so the neighboring anhydrites and salt rocks are pulled to collapse, which ultimately results in drill pipe sticking. Second, borehole deformation and instability in the Lower Fars layer intensify with the increase of inclination angle and wellbore opening time ...

Rebushing rocker arms - MGA Guru

In this case the bore of the bushing is about as large as the length, so the reamer will not self guide, and the rocker arm needs to be set up in a drill press with a vice to hold it for reaming. A single pass with the reamer with a slow speed, lots of oil, and a moderate feed rate makes the bore of the bushing exactly 0.6250" diameter. The rocker shaft is 0.001-0.002 undersize, so the rocker ...

Evaluating Drilling Practice in Deviated Wells .

An accurate estimate of the friction factor(s) during drilling is possible with both downhole and surface torque and WOB sensors. Monitoring the friction factor on a foot-by-foot basis allows such drilling problems as severe doglegs and sticking zones to be diagnosed as they occur. This gives the driller sufficient time to take remedial action--e.g., reaming, adjusting the mud weight, or ...
