Exempel på hur man kan använda DRILLSTRING i en mening

• During the removal of the pipe on Sedco 135, the dancing mud suddenly began to flow up towards the surface; by removing the drillstring the well was swabbed (an effect observed when mud must flow down the annulus to replace displaced drill pipe volume below the bit) leading to a kick.
• This device is typically composed of a body connected to the drillstring, and of mobile parts ("arms", "blocks" or "blades", typically 3 of them) retracted in the body during the descent and extended downhole for the reaming operation.
