Oil drilling construction process
Jun 11, 2018

Drilling is the process of using a rig equipment and a rock breaking tool to crush the formation of a wellbore. The purpose is to conduct geological evaluation, discover oil and gas reservoirs, and develop oil and gas reservoirs. Construction process: drilling → washing wells → pick up singles → start and finish → finish drilling.

Cementing means that a certain size of casing string is introduced into the well, and cement slurry is injected around the well to fix the casing on the well wall to avoid collapse of the well wall. Construction process: Casing to a predetermined depth → Install the cement head, circulating mud, ground surface pipeline → hit the isolation liquid → cement injection → top rubber plug → replace the mud → touch pressure → cement end, wait for the coagulation.
