Definitions
- a collar received about a well casing has radially or tangentially projecting ribs or spines with intervening flexible webbing which is inclined and cupped by the flowing fluid to form generally helical, flow-directing passages which cause swirling of the fiuid and forceful impinging of the fluid against the well bore for cleaning of the same.
- This invention relates to cement dispersers and bore wall and easing cleaners for use in cementing casing in wells.
- an object of the present invention is to provide a bore wall cleaner which will avoid the allegedly harsh action mentioned, yet which will provide adequate cleaning action.
- Another object is to provide a bore wall cleaner embodying a webbing device which substantially traverses the annulus between the casing and bore wall, yet which can readily yield to permit running of the device into a well on the casing and also to permit the passage of cement slurry during the cementing operation.
- Another object of the invention is to provide a cement disperser and/or bore wall cleaner device which is also designed to hydraulically clean the casing wall.
- Still another object is to provide a bore wall cleaner and/ or cement disperser which can function, also, as a cleavage barrier to reduce damage to the cement sheath resulting from perforation operations.
- the device herein illustrated consists in general of a collar for encompassing a casing, preferably rotatably, resilient bracing elements projecting outwardly from the collar, and flexible webbing secured to the bracing elements.
- the webbing is designed to yield when subjected to the force of fluid passing the casing,
- FIG. 1 is an elevation showing the novel bore wall cleaner and cement disperser device installed in a well
- FIG. 3 is an enlarged detail section taken on line 33 of FIG. 2;
- FIG. 4 is a top view of a modified form of bore wall cleaner device mounted on a casing shown in section;
- FIG. 6 shows a cleaner device as in FIG. 1 in combination with a mechanical bore wall cleaner of the scratcher type.
- FIG. 1 shows a section of casing 9 inserted in a well bore 10.
- a collar mounted on the casing, preferably rotatably, is a collar, generally designated 11, having an annular series of holes 12 in each of which is received the coiled intermediate portion 13 of a resilient wire 14.
- Suitable stop means (not shown) will be provided to limit movement of the collar along the casing.
- All of the wires 14, in their unstressed conditions, project generally outwardly and circumferentially of the collar, in the present instance, nearly tangentially.
- the wires will be of suflicient length to permit their extension into a bore wall recess, as indicated by the key seat recess 10a in FIGS. 1 and 2.
- a flexible sheet or webbing Secured to the resilient wires 14, in this instance by molding, is a flexible sheet or webbing, generally designated 24, conveniently made of rubber or other flexible material, either homogeneous or laminated.
- the webbing is thickened about the wires, as at 25, to adequately encompass and secure the same.
- FIG. 2 shows the inner edge of the webbing slightly spaced from the collar, as at 26, but this is not essential and if desired the webbing may closely embrace the outer surface of the collar.
- 27, 23, and 29 are shown three different wire configurations for better securing the same to the Webbing.
- the edge of the collar 34 is shown as scalloped, as at 35, to provide periodical entrances and exits for slurry or other well fluid to bring the same into cleaning contact with the casing wall.
- the main body of the collar is spaced outwardly from the casing, as indicated at 36, and is provided with holes 37 for the same purpose as holes 12 in FIG. 1.
- FIG. 6 shows a bore wall cleaner and cement disperser in general similar to that in FIG. 1 and including a collar 40 rotatable on the casing and with generally tangentially-projecting resilient wires 41 supporting webbing 42. Secured to this collar, as by means of clips 43, is a second collar 44 from which project generally tangential scratcher wires 45 of the type disclosed in the abovementioned Hall Patent No. 2,671,515.
- the cement slurry diverted and directed through helical channels 46 will cause collars 40 and 44 to rotate, providing a mechanical scratching action against the bore wall at the same time as the helical streams of cement or well fluid hydraulically scour the bore wall and inward whiskers, as at 17 and 18 in FIG. 3, mechanically act upon the casing wall.
- the resiliently-braced webbings 24, 30, and 42 of the various forms may yield upwardly, as indicated at the left side of FIG. 1 and in FIG. 6.
- the cement slurry will be pumped in the usual manner downwardly through the casing, thence upwardly in the annulus between the casing and bore wall.
- the slurry engages the webbing it will be distorted upwardly by the force of the cement.
- the resultant pivoting or bending of the resilient wires 14 (FIG.
- the resilient wires 14 will yield in proportion to the force of the cement slurry so as to maintain substantially uniform hydraulic pressure against the bore wall and to accommodate varying rates of pumping.
- the cleaner device should be set abreast a recess, as at a in FIG. 1, the wires can accommodate themselves accordingly.
- the use of the wall cleaner as a kind of motor to rotate a more conventional scratcher, as shown in FIG. 6, may have certain advantages.
- the device may serve as a cleavage barrier for use in the method of cementing and completing described in Patent No. 3,064,- 731.
- the device may serve the multiple purposes of 4 t a cleaner for the bore wall and casing, a cement disperser, and a cleavage barrier.
- a casing cementing tool comprising a collar for mounting about a casing, circumferentially-spaced bracing elements mounted on and projecting outwardly and circumferentially from said collar, and flexible webbing traversing the spaces between said elements, said webbing being yieldable under the influence of fluid moving along the casing to form generally spirally-disposed, fluiddirecting channels for diverting fluid being forced along the casing spirally thereabout.
- bracing elements are laterally yieldable under the influence of fluid being forced along the casing to reduce the distances between said elements and thereby provide channel forming slack in said webbing.
- a cementing tool as described in claim 1 further including channels at the inside of said collar for directing the fluid against the casing wall.
- the combination with a well casing of a cement disperser and bore wall cleaner comprising a collar received about the casing, a plurality of resilient wires secured to and projecting outwardly and circumferentially from said collar, a flexible webbing secured to said wires for diverting and helically directing cement slurry being forced along the easing into cleaning engagement with the bore wall, said collar being rotatable on the casing under the influence of cement slurry being forced through the annulus between the casing and the bore wall, and a mechanical cleaning device secured to said collar and rotatable therewith.
