发明名称 SLOTTED LINER DRILLING
摘要 Drilling assemblies, systems and methods enable a wellbore to be drilled and lined with a slotted liner. A drilling system includes a liner assembly with a drill string in a bore thereof. The drill string and the liner assembly can be selectively coupled together to restrict relative motion between the liner assembly and the drill string. The liner assembly includes a slotted liner portion through which fluid may flow. As the drilling system is used to drill a wellbore, the liner assembly is simultaneously positioned within the wellbore. Once the wellbore is drilled to a desired depth, the drill string can be disengaged from the liner assembly and retrieved from the well. Production fluids such as oil and gas may then be transferred uphole through the liner assembly.
