Description:
A FLUID FLOW ACTIVATED ROTATIONAL CLEANING TOOL

BACKGROUND

[0001] Development of a well site often requires tools to clean the Internal Diameter (ID) of wel l easing. Traditional methods of cleaning often involve fixing a cleaning tool on the end of a running took such as drill pipe, and cleaning the ID by channeling fluid through the ID of the running tool, and rotating the cleaning tool using the running tool. Furthermore, in order to clean 360° of the ID, often it requires the in and out tripping of the tool string, i.e. the up and down movement of the tool string. Another challenge is the activation and deactivation of these cleaning tools when downhole well environment. Traditionally, activation and deactivation of the cleaning tools requires tripping the tools in and out of the well.

[0002] A particular challenge is to clean those areas of well casing that have a critical surface finish. For example, a casing liner is used to tie casing pieces together and until the pieces are tied together sections of the finer, i.e. a tie back receptacle and a bore receptacle (tie forward receptacle), must maintain a high degree surface finish in order to function properly. However, the very action of mechanically rotating and the tripping in and out of the running tool and the cleaning tool can damage these surfaces, as these processes are not always that stable. In summary, rotation of the running tool and cleaning tool and the in and out tripping of the tools can result in damage to the ID of the well casing. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] While the making and using of various embodiments of the present disclosure are discussed in detail below, it should be appreciated that the present disclosure provides many applicable inventive concepts, which can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative and do not delimit the scope of the present disclosure. In the interest of clarity, not all features of an actual implementation may be described in the present disclosure. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developer’s specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0012] The present disclosure relates to a fluid flow activated rotational cleaning tool . The cleaning tool comprises a stationary inner collar fixed to a running tool and a free-floating, rotatable carrier, referred to herein as an outer collar, to channel fluid to the ID of well casing. The outer collar comprises ports. In response to the force of the flow of fluid through the ports, the outer col lar is free to rotate while the inner collar and running tool remains stationary. Turbulence induced by the rotating collar cleans the ID of sections of easing, such as the liner hanger and tie back receptacle and riser. In an embodiment, the outer collar comprises angled ports. In another embodiment, the outer collar comprises angled jet ports. The outer collar can be made from plastics and/or metal . The outer col lar can be milled or molded to include ports. These ports can be fitted with nozzles or otherwise nozzles formed therein. [0013] In an embodiment, the outer collar can be fitted with brushes and wipers made of flexible materials or blades made of hardened material. In another embodiment, the cleaning tool can be fitted with an adjustable, i.e. actionable, sleeve. The sleeve allows for the selective activation and deactivation of the cleaning tool . Hie sleeve can be acted upon either using a mechanical or electromechanical force. Depending on operational requirements, activation can be completed using balls, dans dropped through the running tool, shifting via set down weight like the Turbo Tech® II from Halliburton, a power source, or electromagnetic signals, such as RF signals.

[0014] The cleaning tool can be tripped to the location that needs to be cleaned, fluid can be circulated through the ID of the running tool, i.e. drill string, and out through the jet ports allowing for a 360° cleaning of the annulus of the casing without any rotation, or any significant rotation, of the running tool. The advantage is that the ID of the casing can be cleaned without any significant risk of damage to the casing and use of the tool, i .e. activating/deactivating, doesn’t require tripping in and out of the well.

[0015] Referring now to Fig. 1, illustrated is a diagram of a well site where cleaning operations are performed, in accordance with certain example embodiments, denoted generally as 10. The site 10 comprises a pump and controller station 12, a running tool 14, a drill bit 16, for performing operations other than cleaning, and a cleaning tool 18. The pump and controller station 12 is used to pump well fluid through the running tool 14 and the controller station is used to control operation of the running tool 14 and electromechanical communications to and from the cleaning tool 18. The site 10 further includes well casing 20, liner 22, and liner hanger 24. The liner 22 includes polished receptacles and it is the function of the cleaning tool to clean the ID of liner 22 without causing damage. Well fluid can be pumped from the station 12 through the ID of the running tool and through the drill bit 16 and running tool 18. The fluid flow through the cleaning tool 18 causes an outer sleeve of the cleaning tool 18 to rotate while the running tool remains stationary, or relatively stationary with respect to the cleaning tool. In essence, rotation of the cleaning tool 18, or parts of, does not impart any force or enough force on remaining parts of the running tool 16 to cause the string to oscillate or vibrate.

[0016] Referring now to Figs. 2A and 2B, illustrated are an isometric view and a cut-away isometric view of an outer collar for cleaning tool 18, in accordance with certain example, embodiments, denoted generally as 50. The outer collar 50 cart be made of plastic, e.g. PVC, or metal or metal composite. The outer collar 50 includes ports 52 and the ports 52 can include nozzles 54. The nozzles 54 can be formed with the outer collar 50 or can be after market, threaded nozzles fitted with the outer collar 50. The outer collar 50 can also include slots 56 for receiving different cleaning apparatus ' , such as brushes, wipers, and blades. Although the outer collar 50 can include threaded holes instead of slots 56, or a combination of the two. The cleaning apparatus' can be made of flexible or hardened materials. The flexible material can be one of rubber, wire, nylon, polyester, or combination thereof and the hardened material can comprise at least one metal. Although the hardened cleaning apparatus may not be ideal for cleaning a polished surface area, the running tool may be fitted with multiple cleaning tools 18 where one may be used to clean liner 22, i.e. a newly installed highly, polished liner, and the other used to clean a previously developed casing section that does not require gentle cleaning but rather a hard cleaning.

[0017] Fig. 3 is a cut-away side view of the outer collar 50. As is illustrated, the ports 52 are angled from a radial of the outer collar 50. The angled ports 52 and nozzle 54, i.e. angled jet port, are angled in a way that a portion of force generated by the fluid flow through the jet ports induce rotation of the outer collar in the opposite direction of the fluid flow. Fig. 4 is an isometric view of the outer collar 50 with flexible wipers 58 attached thereto. Although other cleaning apparatus can be used and the outer collar 50 can obviously he fitted with other mechanisms for receiving the cleaning apparatus’.

[0018] Referring now to Figs. 5A-5C, illustrated a cross sectional view' of cleaning tool 18, a side view of cleaning tool 18 having an actionable sleeve, and a control algorithm for control ling a sleeve actuator, in accordance with certain example embodiments, respectively. The cleaning tool comprises 18 comprises the outer collar 50 and an inner collar. The inner collar includes a main body 60, an actionable sleeve 62, and at least one flow port 64. The main body 60 of the inner collar can be coupled with and fixed to the running tool 14. The actionable sleeve 62 can be adjusted to open and close the flow ports 64 so that fluid flowing through the ID 66 of the running tool 14 can be channeled through the flow pons 64 and into the flow jets 52, 54 when needed. A sleeve actuator 68, see Fig. 5B, can be mechanically controlled or electromechamcaliy controlled. The mechanical means by which the actuator 68 can he tripped will be discussed in reference to Figs. 6 and 7. In the case of an electromechamcaliy controlled actuator, the actuator 68 includes control logic that can be activated using a simple power source, e.g. simply on or off - much like a Sight switch, with power deliver from the controller station 12 through a power line or through encoded signals generated and sent from the controller station 12. In the latter case, see Fig. 5C, an actuator can be selected, block 70. This feature can he optional. However, In the event multiple cleaning devices need to be controlled, the option allows for the selective operation of the devices. Once an actuator is selected, the code for the specific actuator is generated, block 72, and the code sent to the selected actuator, block 74, whereupon the actuator 68 causes the sleeve 62 to slide to a position that either opens or closes the flow ports 64. [0019] Referring now to Figs. 6A and 6B, illustrated are cut-away views of a mechanically controllable actionable sleeve 62 in a closed and open position, respectively, according to certain example embodiments. The actionable sleeve, in this embodiment, can be controlled using mechanical force delivered to the sleeve 62. A sheer screw 80, or screws, can be used to maintain the sleeve in the closed position, Fig. 6A, so that there is no fluid flow through the flow ports 64. A ball, not illustrated, can be used to create the mechanical force necessary to break sheer screw ' s 80 allowing the sleeve to move to the open position, Fig. 6B, exposing the flow ports 64 to the ID 66 and the fluid flow · therein
