Cluster Drilling Rigs
The cluster drilling rig has several remarkable features. It can achieves continuous operation of single-row well/double-row well and several wells over a long distance, and it is capable of being moved in both longitudinal and transverse directions. There are various moving types available, Jackup type(Rig Walking Systems),train-type ,two-train type, and its rig equipment can be flexibly adjusted according to specific requirements. Moreover, the shale shaker tank can be moved along with the carrier, while there is no need to move the generator room, electric control room, pump unit and other solid control equipment. Additionally, by utilizing the cable sliding system, the slider can be moved to achieve telescopic cable, which is easy to operate and quite fast.
