摘要
A method of drilling a wellbore that traverses a formation, the method comprising the steps of inserting a one- stage drilling tool into the wellbore, the one- stage drilling tool comprising a laser head configured to produce a drilling beam, a completion sheath configured to line the wellbore, and a centralizer configured to support the completion sheath within the wellbore, operating the laser head to produce the drilling beam, wherein the drilling beam comprises a laser, wherein the drilling beam has a divergent shape comprising a base at a distance from a front end of the laser head and an apex proximate to the front end of the laser head, wherein a diameter of the base of the drilling beam is greater than a diameter of the one- stage drilling tool, and drilling the formation with the drilling beam, wherein the laser of the drilling beam is operable to sublimate the formation.
