Description

ARTICULATED MAST FOR A COILED TUBING RIG
Field of the Invention This invention relates to an articulated mast for use in injection of tubing in well drilling operations.

Background of the Invention In well drilling operations utilizing the coiled tubing technique, rigs are usually constructed on a transport trailer which may carry both the reel of continuous tubing and the mast which supports the tubing during injection and withdrawal of the tubing from the well being formed or serviced. In this arrangement while the mast must be capable of supporting the injection unit over the well, it must be constructed to be lowered to a transport position which allows the trailer to be drawn over not only various forms of terrain, but along public roadways which have, of course, various restrictions, including overhead and width clearances. It is also essential that the mast and the injection unit be capable of quick installation over the well once on site with the minimum of labour and subsequently restored to a transport condition after the well operation is completed.

Summary of the Invention It is an object of the present invention to provide a coiled tubing injection system which is equipped with a versatile mast system capable of compact storage on a transport trailer but one which can be conveniently and quickly moved between operating and travel modes by way of that trailer.

According to the invention there is provided an articulated mast supporting a tubing injector unit for use on a transport trailer of the type having a rear deck portion, the articulated mast including, a lower boom section having, a first connection means connecting one end of the lower boom section to the rear deck portion for pivotal movement from a substantially horizontal position on the rear deck about a transverse axis to a raised substantially vertical position, and first motor means for raising and lowering the lower boom section between the horizontal and raised positions. There is further provided an upper boom section having a main body portion with a second connection means for connecting a first end of the upper boom section to a second end of the lower boom section for pivotal movement of the upper boom section about a transverse axis parallel to the transverse axis of the first connecting means. This achieves raising of the upper boom section from a first horizontal positioned atop the lower boom section in the horizontal position of the lower boom section to a raised slanted position having upward and rearward components. A second motor means is provided for raising and lowering the upper boom section between the positions of the upper boom. The upper boom section includes an extendible portion at a second end thereof and connected to the main body portion of the upper boom section for telescopic movement relative thereto so as to provide positioning of the extendible portion between a retracted position and an extended position for thereby increasing the length of the upper boom when in the extended position. A third motor means is provided for moving the extendible portion between the retracted and extended positions. Connection means is mounted on the extendible portion of the upper boom member for carrying a tubing injection unit.

Detailed Description of the Invention As shown in Figs. 1 to 3, the complete coiled tubing injector system incorporating the articulated mast 10 of the invention is constructed on a road transport trailer 11 for being pulled between drilling sites by way of a tractor (not shown) when connected to the trailer through a fifth wheel system.

The transport trailer 11 provides a front deck portion 12 on which are mounted components 19 which may include, for example, components for supplying pressurized hydraulic fluid, such as an electric motor and pump unit, a hydraulic cooler, and a hydraulic tank. The transport trailer 11 further provides a middle, dropped portion 29 in which is mounted the tubing storage reel 14. The articulated mast 10 is mounted on a rear deck portion 15 of the transport trailer.

The articulated mast 10 includes a first boom or lower section 16 connected to the rearmost part of the rear deck position 15 by way of a transverse pivot connection 17 to allow pivoting of the lower section from a position which is substantially horizontally disposed on the deck (Figs. 1& 4) to an upright position as seen in Figs.
5 to 7. The lower section is provided with motor means 18, which is shown in the form of an expandible hydraulic cylinder connected at one end to the rear deck position forward of the transverse pivot connection 17, and at the other end to the lower section 16 of the mast at a point closer to the opposite end of the lower section 16. Both the lower and upper boom sections are formed by a pair of transversely spaced members as best seen in Fig. 2. On expansion of the hydraulic cylinder, the lower boom section is pivoted in a clockwise direction about pivot connection 17 as is apparent in Fig. 5.

The articulated mast 10 further includes a second boom or upper section 20 which is pivotally connected at a lower end by a transverse pivot connection 21 to the upper end of the lower section 16 for pivotal movement about an axis parallel to the axis of pivotal connection 17. The pivot connection 21 has its axis offset relative to the centre lines of the lower and upper sections 16,20 in order that when the articulated mast is in its lower most position as seen in Figs. 1 and 4, the two sections are juxtaposed and both substantially horizontal and parallel to each other, thus occupying the minimum of height for transport. Mounted between the side members which constitute the lower section 16 there is disposed a second motor means 22, which is again in the form of an expandible hydraulic cylinder, the piston rod of which is connected through a linkage 23 to the upper section 21. This second expandible hydraulic cylinder is pivotally connected at a lower end to the lower section 16, and at its piston end to the linkage so that an expansion of the motor means 22 the upper section is pivoted about, upwardly and away from the lower section 16 as shown first in Fig. 5, and then to its operative position as shown in Fig. 6.

The second boom or upper section 20 includes an extendible portion 24 (Fig.
7) which is contained within the members of the main body of the upper section 20.
This extendible portion is in effect telescopically positioned relative to its main body of upper section 20, and is actuated by a third motor means (not shown) in the form of an expandible hydraulic cylinder, the cylinder of which is within and connected to the main body of the upper section 20 with a piston rod thereof connected to the extendible portion 24. Thus on expansion of this third expandible cylinder, the extendible portion 24 is forced outward relative to the main body portion of the upper section 20 to effectively extend the length of upper section 20 of the mast 10.
The extendible portion 24 is shown in the most projected position in Fig. 7.

A tube injector unit 25 is connected to the outer end of the extendible portion 24 in a manner to pivot about a transverse axis 37 parallel to the axis of the pivot connections 17 and 21. The pivot action of the injector unit 25 relative to extendible portion 24 of the mast 10 is provided through a linkage 26, which is connected between the extendible portion 24 and a framework of the injection unit 25, and includes a motor means 27 in the form of an fourth expandible cylinder. On expansion of the motor means 27, the injector unit 25 is movable from a position in which the main central axis of the injector unit is substantially parallel to the axis of the lower and upper sections (16,20) of the mast in the transport mode as shown in Fig. 1, eventually to a position wherein its main central axis is essentially vertical as positioned over a well head structure 28 as shown in Fig. 7.

The injector unit 25 is of a common form used in the industry, having the main injection drive portion 30 and a gooseneck 31 which directs the tubing 32 being drawn from the storage reel 14 through a smooth curve. The gooseneck 31 is designed to be collapsed as the articulated mast is contracted to a transport mode so as to conveniently occupy a space provided between spaced side members forming the upper and lower sections 16,20 of the mast. As shown the gooseneck consists of three sections, which in the operative form are in position to form a smoothly formed track defini.ng the path of travel of the tubing 32. A main portion 33 of the gooseneck is affixed to the framework of the injection drive portion, and an intermediate portion 34 is hinged to an outer end of main portion 33, the latter being provided with a double action hydraulic cylinder 35 which, when expanded, pushes the intermediate portion 34 to its operating position as shown in dashed lines in Fig.
4. An outer end portion 36 is pivotally connected to the free end of the intermediate portion, with a hinge providing a limited swing into a curvature forming position in order that it is free to swing from a relative straight continuation of the intermediate portion in storage, as shown in Fig. 1 to its operative form as shown in Figs.
5 to 7, the swinging operation being depicted by the two positions illustrated in Fig.
4.

Following through from the relative positions of the articulated mast as shown in Fig. 1 and Figs. 4 to 7, it can be readily seen the manner in which the components of the articulated mast 10 accomplish the feature of providing a mast structure which is compact for storage yet readily converted into an operational mode. It can also be seen that in the transport mode of Fig. 1, the height of the mast and associated injector 30 is no greater than the height of the storage reel located in the dropped portion of the transport trailer.
As indicated in Fig. 4, when the system is to be transformed into the operative condition, the motor means or cylinder 27 is first expanded to tilt the injector drive portion 30 somewhat towards its fmal working position, at which time the hydraulic cylinder 35 is expanded to push the intermediate portion 34 of the gooseneck 31 into its operative position. At this same time, the outer end portion 36 swings to its operative position where it remains because of the form of its hinge as long as the injector drive portion continues from the position shown in Fig. 4 and until it reaches its fmal working position. The boom forming the lower section 16 is then moved towards its operative position by expanding of the hydraulic cylinder forming motor means 18 and activation of hydraulic cylinder form the motor means 22 is also commended to start the raising of the boom forming the upper section 20 as indicated in Fig. 5. As the hydraulic cylinder 22 reaches its normally full extension, the upper boom is brought to its approximate fmal position as shown in Fig. 6.
The third expandible hydraulic cylinder (not shown) is activated to telescope the extendible portions 24 to its fmal position, while the fourth expandible hydraulic cylinder 27 properly positions the injection drive portion 30 of the injection unit vertically over the well head structure 30 (Fig. 7).

After the drilling operation is completed, the hydraulic cylinders are operating substantially in the reverse order to place the overall tubing injection system in condition for transport (Fig 1). It is believed apparent from the above that the system incorporating the articulated mast of the present invention is of a relatively simple design providing for economic manufacture and requiring very little work crew to put it in condition for operation or transport.
