WELL OPERATION METHOD AND A WELL OPERATION EQUIPMENT SYSTEM FOR HANDLING A CONTINUOUS ELONGATE DEVICE TO BE INSERTABLE INTO A WELL

摘要

A well operation method and system for handling a continuous elongate device (CED) (28), such as e.g. coiled tubing, rod, wire or wireline, to be inserted into and retracted from a well (35), comprising: transporting to a well site (35) by a first trailer (21) a movable work platform (23) having a tiltable mast (24) and a CED conveyor apparatus (25, 26) linked to a free end of the mast, deploying at least four legs or outriggers (30-33) out from a platform circumference, lifting the work platform (23) up from and off engagement with the first trailer (21) by means of said legs or outriggers (30-33), moving the trailer (21) away from the work platform (23), transporting a CED reel (29) to a rear end (23″) of the work platform (23) by means of a second trailer (21), causing arms (27) at the rear end (23″) of the work platform (23) to engage the CED reel, lifting the CED reel (23) off the trailer, and bringing the CED (28) in engagement with the conveyor apparatus (25; 26) and a lubricator string (42), wellhead (36) and a well (35).
