Drill stem subs

Drill stem subs are used for connecting parts of drill stems and joining the drilling tools to it. Drill stem is a pipe nipple, made of highly-alloy steel the upper and lower ends of which terminate in locking threads. Drill stem subs are manufactured in all sizes in accordance with GOST 7360-82.

Types of drilling stem subs:

  • P type – bottle neck, box-pin;
  • M type – box, box-box;
  • N type –pin-type, pin-pin.

Drill tubing pipe subs are used to connect tubing pipes of different diameters, underground equipment with threaded tubing connector ends. Drill tubing pipe subs are manufactured in all sizes in accordance with GOST 23979-80.

Milling cutters

Button-hole mills (FZ type) and junk bits (FT type) are used for destroying the metal objects, cement stones over the entire section of the well at repair works. The cutting face concave camber of the milling cutter FZV lets to centralize mill down the hole.

The washover shoe of heavy type (FK type) are used for destroying the metal objects in the annular space between the borehole wall or casing column and production/drilling string at repair works in oil, gas and exploration wells. The connection between milling cutters and fishing string can be threaded or welded.

Taper string mills (FKK type) are used for cutting damaged areas of production strings (wrinkling, scrapped) at workover or cleaning “window” in the string.

Mill-reamers (FRS type) are used for cutting the “window ” in the string at drilling the new hole.

Stabilizers and centralizers

Spiral-blade stabilizer (modification: collar-collar) of KS type and straight-blade stabilizer of KP type are used for borehole expansion and calibration according to the bore bit diameter at drilling in soft, intermediate, hard, low abrasive and abrasive rock.

Spiral-blade stabilizer (modification collar-pin) of KS type and straight-blade stabilizer of KP type are used for string walls calibration to the nominal diameter in case the rock destruction tool is warn, and also used for centralizing and improving rock destruction tool working conditions at drilling in soft, intermediate, hard, low abrasive and abrasive rock.

Our enterprise produces centralizers with the full thread sizes from 98.4 mm to 660.6mm of 2500 mm in length and with the screw according to the customer requirements. Centralizers сan be made as integral blade construction (body and blade are solid unit) and as welded construction (the blades are welded to the body).

Taper taps

Fishing taps (MBU type and LM type) are used for the left in the well drilling string capture and further extraction by cutting-in smooth inner surface of the pipe.

Taper flat taps (LMG type) are used to capture and extraction collars, snaps or other units with hatchways. The capture is made by pressing the tap into hatchway of the unit. The fishing part of the tap has cone smooth surface.

Multi-operated taper taps (MEU type) are used for capturing and the subsequent extraction of the drilling string which is remained in a well, by incision in a smooth internal surface of the tubing string.

Special locking taper taps (MSZ type) are used for capturing the drilling string with the locking connections in the end (collars) by cutting-in the rotary shouldered connection. Finning part of the taper tap is the fishing thread, that repeats the section of the fished pipe rotary shouldered connection.

Special on-stream taper taps (MES type) are used to capture tubing strings by cutting-in the collar thread. Finning part of the taper tap is the fishing thread, that repeats the section of the fished tubing string.

Die collars

Die collars (K and LK types) are used for capturing and subsequent extraction of the drilling pipes or tubing strings, that were left in the well, by cutting-in and screwing on outer surface of the pipe. The difference between die collar type K and type LK is the pin thread for the re-entry guide connection.

Preventers

Double flange tandem ram blowout preventer (PPS-2F or PPS-2FT types) are used for sealing oil and gas wellheads to prevent gas, oil and water inflows while carrying out maintenance, capital and underground repair and perforating, explosive and other geophysical types of work.

The following types of preventers are manufactured:

  • PPS-2F;
  • PPS-2FT;
  • PPSHR.
