Description

BACKGROUND OF THE INVENTION

Well site development often requires tools to clean the inside diameter (ID) of the well casing. Conventional cleaning methods often involve attaching a cleaning tool to the end of a running tool, such as a drill pipe, and cleaning said ID by passing fluid through the running tool ID and rotating the cleaning tool with the running tool. In addition, 360° ID cleaning often requires running and raising the running string, ie moving the running string up and down. Another issue is the activation and deactivation of these cleaning tools under downhole conditions. Traditionally, activation and deactivation of cleaning tools has required running said tools into and out of the well.

A particular problem is the cleaning of those sections of the well casing that have critical surface cleanliness. For example, a casing liner is used to tie the parts of the casing together, and until these parts are mated together, the liner sections, i.e., the liner socket to mate with the liner extension and the receiver with the hole (the liner extension to mate with the liner socket ) must maintain a high degree of surface finish in order to work properly. However, the very act of mechanical rotation, as well as the lowering and raising of the running tool and the cleaning tool, can damage these surfaces because these processes are not always so stable. Thus, rotation of the running tool and cleanout tool, as well as running and retrieving these tools, can damage the casing ID of the well.

SUMMARY OF THE INVENTION

Thus, according to one aspect, a system is provided for use with a string for running tools to clean a casing string in a downhole operation, comprising:

an inner ring containing at least one flow hole; and

an outer ring containing at least one jet orifice in fluid communication with the at least one orifice;

wherein the inner ring is connected to the outer section of the running string and the outer ring is rotatable about the inner ring in response to fluid flow through the running string.

The inner ring preferably further comprises a drive sleeve, wherein the drive sleeve is movable from a first position to a second position causing at least one jet to be in fluid communication with the at least one orifice in response to fluid flow through the running string .

The inner ring preferably remains relatively stationary with respect to the rotation of the outer ring.

The at least one jet opening is preferably angled such that part of the force generated by fluid flow through the jet openings causes the outer ring to rotate in a direction opposite to the fluid flow.

The outer ring preferably contains at least one of the following:

at least one scraper made of a flexible material;

activation of a cleaning apparatus attached to the running string, wherein the cleaning apparatus comprises:

an inner ring connected to the outer section of the running string and including at least a flow port; and

DETAILED DESCRIPTION

While the making and use of various embodiments of the present disclosure is discussed in detail below, it should be appreciated that the present disclosure provides many applicable inventive concepts that may be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative and do not limit the scope of the present disclosure. In the interests of clarity, not all features of an actual implementation may be described in this disclosure. Of course, it will be appreciated that in developing any such actual implementation, many implementation decisions must be made to achieve the developer's specific goals, such as meeting system and business constraints, which will differ from one implementation to another. In addition, it should be understood that such development can be complex and time consuming, but will be a routine task for those skilled in the art who benefit from this disclosure.

The present disclosure relates to a rotating cleaning tool activated by fluid flow. The cleaning tool includes a stationary inner ring attached to the running tool and a free-floating rotatable holder, referred to herein as the outer ring, to guide fluid to the well casing ID. The outer ring contains holes. In response to the force of fluid flow through said holes, the outer ring is free to rotate while the inner ring and running tool remain stationary. The turbulence caused by the rotating ring clears the ID of the casing sections such as the liner hanger, liner liner seat and riser. In one embodiment, the outer ring contains corner holes. In one embodiment, the outer ring contains angled jet holes. The outer ring may be made of plastic and/or metal. The outer ring can be milled or molded with holes. These openings may be provided with nozzles or other nozzles formed therein.

In one embodiment, the outer ring may be provided with brushes and scrapers made from flexible materials or blades made from a rigid material. In another embodiment, the cleaning tool may be provided with an adjustable, ie running, bushing. Said sleeve allows selective activation and deactivation of the cleaning tool. This sleeve can be acted upon using both mechanical and electromechanical forces. Depending on operational requirements, activation can be completed using balls, darts thrown through a trigger tool, displacement with a mounted mass like Halliburton's Turbo Tech® II, a power source, or electromagnetic signals such as radio frequency (RF) signals.

The cleaning tool can be run to the location to be cleaned, the fluid can be circulated through the ID of the running tool, i.e. the drill string, and out through the jet holes, allowing 360° cleaning of the casing annulus without any rotation or any significant descending tool rotation. The advantage is that the casing ID can be cleared without any significant risk of damaging the casing, and the use of said tool, ie activation/deactivation, does not require running in and out of the well.

Let us now turn to FIG. 1, which depicts a diagram of a drilling site during cleanup operations, in accordance with some exemplary embodiments, indicated generally as 10. Said site 10 includes 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 the well fluid through the running tool 14, and the controller station is used to control the operation of the running tool 14 and electromechanically communicate to and from the cleaning tool 18. The platform 10 further comprises a well casing 20, a liner 22, and a liner hanger 24. The shank 22 contains polished pockets, and the function of the cleaning tool is to clean the ID of the shank 22 without damaging it. Downhole fluid can be pumped from station 12 through the running tool ID and through the drill bit 16 and the running tool 18. The flow of fluid through the cleaning tool 18 causes the outer sleeve of the cleaning tool 18 to rotate while the running tool remains stationary or relatively stationary with respect to the cleaning tool. As such, rotation of the cleaning tool 18 or parts thereof does not impart any force or sufficient force to the remaining parts of the running tool 16 to cause said string to oscillate or vibrate.

Let us now turn to FIG. 2A and 2B, which are isometric and cutaway isometric views of an outer ring for a cleaning tool 18, in accordance with some exemplary embodiments, designated generally as 50. The outer ring 50 may be made of plastic, for example, PVC, either metal or metal composite. Outer ring 50 includes openings 52, and openings 52 may include nozzles 54. Nozzles 54 may be formed with an outer ring 50 or may be aftermarket threaded nozzles provided with outer ring 50. Outer ring 50 may also include slots 56 for receiving various cleaning devices such as brushes, scrapers and blades. Although the outer ring 50 may contain threaded holes instead of slots 56, or a combination thereof. The cleaning apparatus can be made of flexible or rigid materials. The flexible material may be one of rubber, wire, nylon, polyester, or a combination thereof, and the rigid material may comprise at least one metal. Although a rigid cleaning apparatus may not be ideal for cleaning the polished area, the running tool can be equipped with several cleaning tools 18, one of which can be used to clean the shank 22, i.e. a newly installed well polished shank, and the other can be used to clean a pre-deployed section of casing that does not require gentle cleaning, but rather hard cleaning.

Fig. 3 is a sectional side view of the outer ring 50. As shown, the holes 52 are angled with respect to the radius of the outer ring 50. The corner holes 52 and the nozzle 54, i.e. the corner jet holes, are angled so that part of the force generated fluid flow through the jet holes causes the outer ring to rotate in the opposite direction to the fluid flow. Fig. 4 is an isometric view of outer ring 50 with flexible scrapers 58 attached thereto. Although other cleaners may be used, outer ring 50 can obviously be provided with other mechanisms to receive the cleaner.

Let us now turn to FIG. 5A-5C, which show a sectional view of a cleaning tool 18, a side view of a cleaning tool 18 having a bushing, and a control algorithm for driving the bushing, respectively, in accordance with some exemplary embodiments. The cleaning tool 18 includes an outer ring 50 and an inner ring. The inner ring includes a main body 60, a running sleeve 62, and at least one dispensing port 64. The main body 60 of the inner ring can be connected to and attached to the running tool 14. The drive sleeve 62 can be adjusted to open and close the flow ports 64 so that the fluid flowing through the ID 66 of the running tool 14 can be directed through the flow ports 64 into the flow jets 52, 54 when needed. Hub drive 68, see FIG. 5V, can be mechanically controlled or electromechanically controlled. The mechanical means by which actuator 68 can be operated will be described with reference to FIG. 6 and 7. In the case of an electromechanically controlled drive, the drive 68 contains control logic that can be activated using a simple power supply, such as simply turning it on or off - like a light switch, with power supplied from the controller station 12 through the power line or through coded signals generated and sent by the station 12 of the controller. In the latter case, see FIG. 5C, block 70, a drive may be selected. This flag may be optional. However, if it is necessary to control several devices for cleaning, this option provides the possibility of selective operation of these devices. Once a drive is selected, a drive-specific code is generated, block 72, and that code is sent to the selected drive, block 74, whereupon drive 68 causes sleeve 62 to slide into a position that either opens or closes dispensing ports 64.

Let us now turn to FIG. 6A and 6B, which are sectional views of the mechanically operated travel sleeve 62 in the closed and open positions, respectively, in accordance with some exemplary embodiments. In this embodiment, the bushing may be controlled by a mechanical force applied to the bushing 62. A shear screw 80 or screws may be used to hold the bushing in the closed position, FIG. 6A so that there is no fluid flow through the flow ports 64. A ball (not shown) can be applied to generate the mechanical force necessary to break the shear screws 80 allowing the sleeve to move to the open position, FIG. 6B, opening flow ports 64 for ID 66 and fluid flow therein.
