- Drill_string_compensator abstract "A drill string compensator decreases the influence of the heave of a drilling vessel on the drill bit. Drill string compensators are also known under the more general name: heave compensator. Drill string compensators are used onboard drill ships and semi-submersible drill rigs. There are two major types of drill string compensators: Drill string compensator between the traveling block and hook . Top mounted heave compensatorDrill string compensators are just giant springs between the drill bit and rig. These consist of one or more hydraulic cylinders and air bottles. In between, a medium separator is sometimes used. If there is no spring element, movement of the drill rig would immediately place enormous forces on the drill bit and pull the drill bit off the bottom of the hole.A spring has a force/displacement curve. To get only small force variations on the drill bit, the hysteresis of the spring should be small and the curve should be horizontal, or the gas volume should be large. This is more difficult for a hook-mounted compensator than for a top-mounted one. Several patents are in use for a solution to provide this horizontal curve with a relatively small volume of gas. It will be clear that these (kinematic) constructions can in fact only be used in a top-mounted heave compensator.".
