Definitions
- the invention relates to a method and system for enhancing the performance of a well tubular expansion assembly .
- a disadvantage of the known method is that, in particular in deep and/or deviated wells, the drill string pull exerted to the cone may be limited and insufficient to expand an upper end of the tubular within a lower end of a previously installed well tubular.
- a further disadvantage of the known method is that it requires use of a top anchor that fixes an upper end of the expanded tubular within a previously installed tubular, which anchor may slip if a large upward force is exerted by the expansion cone to the expanding tubular .
- a known method for placing an expandable bottom plug at the bottom of an expandable well casing is expanded downhole is disclosed in International patent application WO2004/027200. This known method involves a two step installation and expansion process which requires intervention by an operator. There is a need for an improved bottom plug installation and subsequent expansion process that can be performed in one step without intervention of an operator.
- a method for enhancing the upward force on an expansion cone which is pulled up by a drill string to expand a well tubular comprising:
- the expanded lower edge of the well tubular has an inwardly curved shape and the bottom plug comprises :
- the fluid injection through the interior of the drill string may be continued when the expansion cone is pulled through the upper end of the lower tubular into the lower end of the previously installed upper tubular and the drill string pull and pressure of the fluid injected through the drill string may be adjusted on the basis of a monitored longitudinal movement of the expansion cone through the well tubular and a ration between downward hydraulic force exerted on the bottom plug and upward force exerted by the expansion cone on the tubular expanded thereby.
- the bottom plug may be drilled out and the expanded well tubular may then form another previously installed well tubular through which a subsequent well tubular is inserted and expanded in accordance with the method according to the inventon, which process may repeated several times to generate a MOnoDiameter (MOD ) well hydrocarbon fluid production well with a substantially constant internal diameter through which, after completion of the well, a larger flux of crude oil, natural gas and/or another hydrocarbon fluid may be produced than through
- MOD MOnoDiameter
- Fig.l shows how a well tubular is expanded by puling an expansion cone therethrough
- Fig 2 shows how the upper end of the well tubular is expanded within a lower end of an previously installed well tubular after completion of the
- FIG.3 shows that the expansion assembly according to the invention is provided with a bottom plug suspended below the expansion cone;
- Fig.4 shows how the upward force exerted on the expansion cone is increased by pumping fluid between the expansion cone an bottom plug after pulling the bottom plug into sealing engagement with a lower edge of the expanded well tubular.
- Figure 1 shows how a lower well tubular 1 is expanded by moving an expansion cone 2 therethrough.
- the expansion cone is connected to a drill string 3 that is pulled up, as illustrated by arrow 4, whilst the upper end 1A of the lower tubular is maintained in a fixed position within a previously installed upper well tubular 5 by a radially expanded top anchor assembly 6.
- an inner surface of the lower tubular 1 is coated with a lubricating coating 7 to lubricate the longitudinal movement of the cone 2 therethrough.
- Figure 3 shows that the expansion assembly according to the invention is provided with an expandable bottom plug 10 suspended at a carrier body 11 below the expansion cone 2.
- the lower end of the carrier body 11 is provided with a self-releasing joint 12, which disconnects the bottom plug 10 from the carrier body 11 when the bottom plug is pulled into a lower edge 13 of the expanded tubular as illustrated in Fig.4.
- Figure 4 shows how the upward force F exerted on the expansion cone 2 is increased by pumping, as illustrated by arrows 14, pressurized fluid through the drill string 3 and a fluid discharge port 15 below the cone 2 into a space 16 between the expansion cone 2 and bottom plug 10 and into the bottom plug 10 to expand the plug 10 and simultaneously pulling the expanded bottom plug 10 into sealing engagement with the lower edge 13 of the expanded well tubular 1 to provide a hydraulic force F 2 that supplements the mechanical force F i exerted by the drill string pull on the cone 2.
- the hydraulic force F 2 and mechanical force F i jointly push the cone 2 up through the expanding tubular 1, which is particularly relevant when the upper part of the expanding tubular 1 is expanded within the lower end of a previously installed tubular 5 in which case both tubulars 1 and 5 may be expanded into a sealing
- FIGS 3 and 4 also show that a top anchor 17 may be expanded against the inner surface of the previously installed tubular 5 to inhibit upward movement of the lower tubular 1 during the expansion process. It will be understood that if the downward force F 2 exerted by the injected pressurized fluid 14 via the bottom plug 10 on the expanded tubular 1 is larger than the upward mechanical force F i exerted by drill string pull on the cone and expanding tubular 1 there is no need to use a top anchor 17.
