Title: Acceptance of imported coiled tubing and its application in Sichuan Oilfield
Abstract: Two sets of advanced coiled tubing are imported from U.S.A by SPA.One is 32 coiled tubing,with working depth of 5 000 m.The other is 38 coiled tubing,with working depth of 3 200 m. During field acceptance in well Tieshan 5 of east Sichuan,tubing plugging problems caused by perforation are solved by flushing and drilling.Imported coiled tubings of different pipe diameters and operating depthes can conduct workover treatment under snubbing conditions in east,central Sichuan or on other old wells.They will largely shorten construction period and reduce production cost.
