Abstract
Abstract A device adapted to be mounted on a drill pipe and inserted in a well casing with a radially movable impact member resiliently urged into engagement with the casing and repeatedly moved away from engagement and released for causing an impact upon rotation of the drill pipe while the device is resiliently held from rotating relative to the casing. The method of cementing or gravel packing the casing in the well by the use of such devices to vibrate the casing while the cement slurry or gravel is pumped through the drill pipe and into the annulus surrounding the casing and including the step of clearing the cement slurry from the drill pipe by a following plug pumped down the drill pipe.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
151 words
In a method for cementing a casing in a well bore using a drill pipe with rotation-actuated basing vibrating devices thereon, comprising steps of: positioning the casing in the well bore with the drill pipe extending to and engaging the lower end of the casing and with the casing vibrating devices positioned within the casing; pumping cement slurry down the drill pipe to and through the lower end of the casing into the surrounding annulus; rotating the drill pipe during said pumping for actuating the casing vibrating devices to vibrate the casing and enhance the complete filling of the annulus; inserting a plug in the drill pipe immediately following the desired amount of cement slurry and pumping said plug to the lower end of the casing foR clearing the cement slurry from the drill pipe; and discontinuing pumping and rotation and removing the drill pipe and vibrating devices from the well.
Claim 2
Dependent Claim
100 words
In a well tool for radially jarring a casing located at a remote depth in a well through the use of a drill pipe, comprising: a mandrel adapted to be connected to the drill pipe; means rotatably supported on said mandrel including an impact member mounted for movement toward the casing relative to said mandrel; said means having means for resisting rotation relative to the casing; and interengaging means on said mandrel and impact member operable upon rotation of the drill pipe and mandrel for repeatedly and consequently causing movement of said impact member into impacting engagement with the casing.
Claim 3
Dependent Claim
35 words
The well tool of claim 3 wherein biasing means urge said impact member toward said impacting engagement with the casing and said interengaging means causing a biasing movement and then release of said impact member.
Claim 4
Dependent Claim
28 words
The well tool of claim 3 wherein said means for resisting rotation relative to the casing comprises an axially extending leaf spring bowed outwardly to engage the casing.
Claim 5
Dependent Claim
29 words
The well tool of claim 5 wherein said impact member is movable toward casing and impacting engagement diametrically opposed to the engagement of said leaf spring with the casing.
Claim 6
Dependent Claim
113 words
In a well tool for radially jarring a casing located at a remote depth in a well through the use of a drill pipe, comprising: a mandrel adapted to be connected to the drill pipe; a support body rotatably mounted on said mandrel and having means for engaging the casing for resisting rotation of the support body relative to the casing; and impact member mounted on said support body for movement toward the casing relative to said support body; and interengaging means on said mandrel and impact member operable upon rotation of the drill pipe and mandrel for repeatedly and sequently causing movement of said impact member into impacting engagement with the casing.
Claim 7
Dependent Claim
35 words
The well tool of claim 7 wherein biasing means urge said impact member toward said impacting engagement with the casing and said interengaging means causing a biasing movement and then release of said impact member.
Claim 8
Dependent Claim
158 words
In a well tool for radially jarring a casing located at a remote depth in a well through the use of a drill pipe, comprising: a tubular mandrel adapted to be connected to the drill pipe and positioned within the casing; a support body rotatably mounted on said mandrel and having means for engaging the casing for resisting rotation of the support body relative to the casing; an impact member mounted on said support body for movement of said impact member toward the casing relative to said support body; means resiliently urging said impact member toward the casing relative to the support body; and interengaging means on said mandrel and impact member operable upon rotation of the drill pipe and mandrel for repeatedly and sequently first moving said impact member away from the casing in opposition to the urging of said resilient means and then releasing said impact member for rapid movement into impacting engagement with the casing.
Claim 9
Dependent Claim
33 words
The well tool of claim 9 wherein said means for engaging the casing and resisting rotation comprises and outwardly bowed leaf spring mounted on said support body to extend axially of the casing.
Claim 10
Dependent Claim
32 words
The well tool of claim 10 wherein said leaf spring is positioned on said support body for engaging the casing directly opposite the location of impacting casing engagement by said impact member.
Claim 11
Dependent Claim
55 words
The well tool of claim 9 wherein said support body comprises two axially spaced members rotatably mounted on said mandrel with said impact member positioned therebetween, and parallel mating slideways are provided on said impact member and two members for allowing said movement of the impact member and preventing relative rotation among the three members.
Claim 12
Dependent Claim
28 words
The well tool of claim 12 wherein said slideways are perpendicular tO the axis of rotation of the mandrel for causing radial impacting movement of said impact member.
Claim 13
Dependent Claim
73 words
The well tool of claim 12 wherein said resilient means for urging the impact member comprise a plurality of spring rods positioned on both sides of said three members relative to the movement of said impact member and extending longitudinally between and mounted on said two support body members, and means connecting said spring rods to said impact member whereby movement of said impact member away from the casing biases said spring rods.
Claim 14
Dependent Claim
36 words
The well tool of claim 9 wherein said means for engaging the casing for resisting rotation comprises means resiliently urging the support body into engagement with the casing on the same side as the impacting engagement.
Claim 15
Dependent Claim
38 words
The well tool of claim 9 wherein said impact member has a large curved face for engaging the casing for impacting and said face has ports therein for allowing fluid movement therethrough to avoid resistance to the impact.
Claim 16
Dependent Claim
56 words
The well tool of claim 9 wherein said interengaging means comprise a longitudinally extending rib on said mandrel and cam on said impact member with said cam positioned to be engaged by said rib to move the impact member away from the casing and to release the impact member as the rib rotates passed the cam.
Claim 17
Dependent Claim
143 words
In a method for compactly placing a material externally of a liner in a well bore through a port collar in the liner using a drill pipe with vibrating devices thereon, comprising steps of: positioning the casing in the well bore with the drill pipe extending into the liner with the casing vibrating devices positioned within the liner; manipulating the drill pipe to open the port collar to connect the drill pipe in fluid communication with the exterior of the liner; pumping the material down the drill pipe to and out through the port collar into the surrounding annulus; rotating the drill pipe during said pumping for actuating the vibrating devices to vibrate the liner and enhance the complete filling of the annulus; manipulating the drill pipe to close the port collar; and removing the drill pipe and vibrating devices from the well.
Claim 18
Dependent Claim
78 words
The method of claim 18 wherein multiple space zones in the well bore are to be filled with such material and a port collar is provided adjacent each zone, including the steps of successively moving the drill pipe from a position opposite one zone to other zones after placing the material and closing the port collar at said one zone and then opening the port collar opposite said other zone and successively repeating the method at each zone.
