Power drilling swivel VBS-100R1

Power drilling swivel is designed to transfer the rotation of the upper part of the drill string during drilling operations, as well as the overhaul of oil and gas wells, including sidetracking. The swivel is supplied with a power unit that ensures the rotation of the swivel shaft with a set torque and a smooth change in the frequency and direction of rotation, braking of the pipe string.

Speed control is carried out by changing the working volume of the main hydraulic pump and hydraulic motor, without changing the engine speed. Increasing the speed of rotation of the output shaft of the swivel to 60 rpm is carried out by increasing the working volume of the hydraulic pump at the maximum volume of the hydraulic motor. A further increase in the speed is achieved by reducing the working volume of the hydraulic motor. Braking and holding the position of the column is carried out by hydraulic motors, the maximum braking force is equal to the maximum torque.

Power drilling swivel VBS-100R1Power drilling swivel VBS-100R1

Power swivel (fig.3) consist of body (pos.1) with gooseneck (pos.2), bail (pos.3),mounted in the lugs of the body (pos.1) with the possibility of swinging on the fingers (pos.4), stem (pos.5) with kelly valve (pos.6), mounted on bearings (pos.7,8 & 9) with slewing capacity in the body (pos.1), top seal (pos.10) and bottom seal (pos.11). The top seal (pos.10) is quick-detachable and is connected to the gooseneck (pos.2) and the stem (pos.5) with nuts (pos.12 & 13). The hydraulic motor (pos.14) is mounted on a gearbox (pos.17) through which is transmit rotation to the stem (pos.5) through gears. The hydraulic motor (pos.14) is powered from a hydraulic station installed on the frame (not shown in Fig. 3). The station pump, which pumps fluid to the hydraulic motor, is driven by a diesel engine. To prevent unscrewing during reverse movement, kelly valve (pos.6) is brace against the stem (pos.5) with a clamp (pos.15).

Under the swivel there is a rotary adapter for mounting elevator links (pos.18). Its angular location relative to the drilling rig is adjusted before starting work and is fixed with a clamping screw.

The reaction bars 16 are connected to the guys rope and prevent the rotation of the swivel from the reaction torque. The reaction bars are easily detached from the guys and from the swivel during transportation. The use of two backstay cable, the common plane of which passes through the hole axis, eliminates the possibility of generating a force targeted at deflecting the swivel output shaft from the hole axis. The tension force of the backstay cable is 2250 kgf. The ends of the bars are equipped with rollers on rolling bearings, which make safer work and reduce cable wear.

Mast equipment

Pair swivel mast equipment kit consist of mounting arrangement to drilling structure (pos.1), ratchet-type tensioner (pos.2), wheel (pos.3), wire-rope guy (pos.4), oil derrick mounting arrangement (pos.5), safety cable gear (pos.6). The drilling hose and hydraulic drive hoses are attached to the standard device for attaching the drilling hose of the well servicing unit. Optionally, it is possible to manufacture a clamp with fastening to the derrick for fixing the hydraulic drive hoses. The drilling hose is not included in the delivery package; there is no space for its storage in the hydraulic station. Hydraulic drive hoses are included in the delivery set (see Table 2), mounted on the hydraulic station drum. It is possible to partially unwind the drum to an incomplete length of the sleeves.
