Definitions
- the present inveniton relates to the production of oil and gas from a well, and more particularly, relates to apparatus and a method for hanging a casing in a casing head whereby the casing is positively locked in the casing head prior to cementing the casing in the formation.
- a further object of the present invention is to provide 3,279,539 Patented Oct. 18, 1966 a casing hanger assembly having hydraulically actuated locking means to hold the sealing element seat after setting pressure has been released.
- Another object of the present invention is to provide a casing hanger assembly having pressure equalizing means to prevent premature setting of the seal between the casing and the casing head by pressure differentials to which the casing hanger assembly may be subjected during the cementing operation.
- FIG. 1 shows the casing hung according to the present invention within the casing head showing the casing head and tubing head mounted in a well;
- FIG. 2 shows in partial cross section the casing hanger locking and sealing apparatus
- FIG. 3 shows in partial cross section the casing hanger running and setting tool used in conjunction with the present invention
- FIG. 4 is a view, partly in section and partly in elevation, of a form of the present invention modified for hydraulic setting of the casing hanger seal, showing the casing hanger as it is carried in the hole by the running and setting tool and landed against the indexing shoulder in the casing head;
- FIG. 5 is a view, partly in section and partly in elevation, showing the relation of the apparatus of FIG. 4 at the point directly after the cementing operation is carried out showing the plugs in place in the landing collar.
- FIG. '6 is a view, partly in section and partly in elevation showing the relation of the apparatus of FIGS. 4 and 5 after the setting ball is dropped through the setting string and pressure is applied to set the packer;
- FIG. 7 is a view, partly in section and partly in elevation, showing the relation of the apparatus of FIGS. 4-6 as the setting tool is released from the casing hanger and is being removed from the hole.
- our present invention involves a means for hanging the casing 60 within a casing head 61 by locking the casing down on a shoulder 79 within the casing head with a spring loaded dog 80, after which the casing can be cemented into the formation prior to setting the packer 94 so that the cement returns may be circulated through the annulus 81.
- the expression casing head as used herein refers to any well member in which a casing is landed or hung, including a casing hanger mandrel where multiple casings are hung one within another.
- the packing element 94 is then extruded to seal off the annulus 81 without making an additional trip into the hole, that is without retrieving the running tool and then running a setting tool to position packing or sealing means.
- a casing hanger mandrel 62 is installed on the upper end of the casing string 60 equipped with a conventional shoe and collar (not shown) on and near the bottom thereof.
- the casing hanger running and setting tool 63 shown in FIG. 3, is then inserted in the easing hanger mandrel 62 with the lugs 64 of the setting nut 66 entering the splines 68 of the casing hanger drive sleeve 92 and the running and setting tool lowered into the casing hanger mandrel '62 on a drill pipe (not shown) until the bearing race 72 rests on top 74 of the mandrel of the casing hanger mandrel 62.
- the floating nut 76 of the running and setting tool which nut is connected thereto by interengaging longitudinal splines, is threaded into the casing hanger at 78 by rotating the drill pipe to the left.
- the running and setting tool 63 to the left moves the setting nut upwardly, the longitudinal spacing of nut 66 and the number of turns required to move nut 66 up to the position shown are such that the floating nut 76 engages the casing hanger at 78 before the setting nut 66 reaches the shoulder as shown in FIG. 3.
- Tool 63 is a running tool for the casing string and because of one advantage of applicants invention, this tool may also serve as a setting tool since an additional trip into the casing head with a setting tool to set packing means may be obviated. Thus, it has been found advantageous to design therunning tool 63 to perform the setting function, although the casing hanger may also be run and the packing means set with a separate tool.
- the casing hanger with a casing string attached thereto and running and setting tool inserted therein, is lowered into the well through the blowout preventers (not shown) on the drill string until the dogs 80 are below the shoulder 82 of the casing head 61, as shown in FIG. 2.
- the casing hanger 62 is then locked down into the casing head 61 since the spring loaded dogs 80 prevent the casing hanger mandrel 62 from moving upward past the shoulder 82 of the casing head.
- the casing is positively locked down prior to cementing before packing oif the annular opening 81 between the casing hanger mandrel 62 and the casing head 61 with the packing rubber 94, so that cement returns may pass through the annular opening 81 and circumferentially spaced slots 83 without provision for an additional outlet or port collar below the casing hanger to provide for the expulsion of cement returns from the casing annulus.
- the shoulder of the casing hanger mandrel which seats on internal shoulder 79 of the casing head, may be any type of interrupted shoulder.
- the casing string is then cemented in the formation by pumping cement through the drill string (not shown) and through the running and setting tool 63 in the conventional manner.
- Pump down plug 84 may thenbe run through the drill pipe with mud and into the position shown in the bottom of the setting tool of FIG. 3 so that the plug 84 engages the liner wiper plug 86, as shown in FIG. 3. thus releasing the liner wiper plug 86 having the pump down plug 84 lodged therein so that the plugs move down the casing to engage the landing collar (not shown)with which they act as a back pressure valve, and effectively pack off the casing after the cement is in place.
- the purpose of the pump down plug is to separate the cement from the mud with which the cement is chased.
- the packing element 94 is extruded between'the casing hanger mandrel 62 and the casing head 61 by first disengaging the fioating nut 76 from the casing hanger mandrel 62 by rotating the drill pipe (to which the running and setting tool 63 is threadably engaged) to the right. Further rotation of the drill pipe (running and setting tool 63) to the right after the floating nut 76 is released from the casing hanger, drives the setting nut 66 which engages splines 68 downwardly toward the lower shoulder 75 of the top sub.
- extrude means that the packer or sealing element, e.g. packer 94, is mechanically compressed to form a fluid-tight seal between two members, e.g. casing head 61 and easing hanger mandrel 62. After extruding packer 94, the casing is hung and sealed in the casing head 61 and the casing hanger running and setting tool 63 may be withdrawn from the casing hanger on the An increase in mud pressure shears pin 88,
- An addition-a1 casing may be hung in an identical manner within the casing hanger mandrel 62..
- a tubing head as, for example, that shown in FIG. 1, may then be latched or fastened to the casing head and a tubing hung therein through the casing hanger mandrel 62 in any conventional manner,-such as that set forth in our copending application, Serial No. 310,203 filed September 20, 1963 for Tubing Head Apparatus and Method.
- the casing hanger assembly shown in FIGS. 1-3 and described above requires rotation to set the packer which packs off between the casing hanger and the casing head in which it is landed.
- the barge may become misaligned with the well bore and it is sometimes difficult to rotate the setting tool string from the.
- FIGS. 4-7 The modification shown in FIGS. 4-7 is particularly useful in applications Where the above-mentioned difficulty may be present.
- FIGS. 4-7 show generally a hydraulic setting means for the-packing element of a casing hanger which is set after the casing hanger has been locked in place in the casing head and after the casing has been cemented into the formation so that cement returns may be circulated through the annulus, as mentioned in conjunction with the description of FIGS. l-3.
- the apparatus of FIGS. 4-7 also involves a hydraulically actuated locking means that holds the packing element set after setting pressure is released and a novel pressure equalizing means that prevents premature set of the packing element by pressure differentials involved in the cementing operation.
