OPERATION RESULTS OF ADJUSTABLE DRIFT ANGLE TURBODRILLS IN PERM BRANCH OF EURASIA DRILLING COMPANY.

CJSC “Gidrobur-servis”
T02-type turbodrills-deflectors and Sh01-type spindles-deflectors developed in the seventies of the past century have some design deficiencies and thus have short lifetime and are unable to build the desired well path. CJSC “Gidrobur-servis” developed ShOT-type spindle-deflector with sealed joint that allowed to simplify the tool design and increase its service life to meet drilling technology requirements. Later, an adjustable deflecting device was developed to replace bent subs.
Combined with one or two unified turbine sections, the O 240 mm (ShOTR-240) and O 195 mm (ShOTR -195) adjustable drift angle spindles-deflectors form turbodrills of TShOTR type. More than 30 sets of this equipment have been used in the Perm branch of LLC “Eurasia Drilling Company” in 2007-2009. The penetration rate increased by 8 percent during a year period as the company started to use the tools. The average operating time exceeds 150 hours, sometimes time to repair is longer than 300 hours.
Key words: turbodrill-deflector; spindle-deflector; sealed joint; well path; CJSC “Gidrobur-servis”; Perm branch of LLC “Eurasia Drilling Company”; cooperation; adjustable deflecting device; drilling speed; reliability.
