Drilling rig masts description:
Mast types are including A type, K type (open-front type), derrick,
mast and bootstrap etc type.
The shape of A-mast section is rectangle or triangle. A-mast has
attractive features of high loading capacity and perfect local
stability. Each section of A-mast is connected by pins. The mast is
assembled in the ground and raised or lowered integrally by the
power of drawworks upon the gin poles.
The shape of K-mast section is “K” open face type. The beam legs
adopt laminated girder structure. Each section of the mast is
connected by pins. K masts can be assembled on the ground and
raised or lowered integrally by the power of the drawworks upon the
The mast will incline to the wellhead during the drilling operation
and keep their stability and load capacity by guy lines.
The bootstrap mast which is the latest line product developed is a
kind of telescoping and erecting mast which can be assembled
vertically. The main feature is that the boot strap mast can be
divided into several sections along the vertical direction.
The base section will be as the guide section and the support
section to raise and assemble the other sections in turn by the
power of drawworks or the hydraulic power,which can save the field
greatly for installation of drilling rig.
