METHOD OF ASSEMBLY OF ECHELON-TYPE DRILLING RIG Russian patent published in 2015 - IPC E21B19/00 

FIELD: process engineering.

SUBSTANCE: invention relates to cluster drilling. Proposed method comprises delivery of assembly units to the sire, arrangement of said assembly units as required, mounting of drilling rig by coupling said assembly units, power tests and disassembly of drilling rig for shipment to customer. Note here that all jobs are performed at the site in definite order with displacement of assembly units in guides erected at said site. Guide length varies with at least three drilling rigs. Said guides are conventionally divided into three zones: Erection, testing and disassembling and shipment zones. Power test bench is arranged at guide mid part. Arrangement of assembly units and parts and assembly of the first drilling rid are performed in assembly zone. First drilling rig assembled, it is displaced in guides to power tests zone to allow assembly of the second drilling rig. Tested first drilling rig is displaced to disassembly and shipment one to displace second drilling rig to power tests zone. Third drilling rig is assembled and, additionally, drilling rig systems are tested for serviceability in whatever said zone.

EFFECT: higher efficiency, accelerated assembly-disassembly.
