- This invention relates to methods and apparatus for use in oil and gas wells, andmore'particularly, for deep gas well Completions where long strings of tubing, high pressure and temperatures, huge stimulation treatments and high-production rates give rise to unusual problems. i
- the present invention involves the location in a borehole of upper and lowerpacker bore receptacles, each having packer bores so that such packer bores straddle an earth strata for the production of hydrocarbons-
- the receptacles are cemented. at their locations and the earth strata intermediate of the receptacles is-placed into fluid communication'with a bore of tubular pipe or casing connecting thereceptacles.
- Thepacker bores of the receptacles are closed off with packing means associated with a string of tubing to form an enclosed volume between the packer bores of the upper and lower receptacles and the bore of the connecting pipe or casing.
- the enclosed volume has its ends defined by the cross-sectional areas of the packer bores inthe upper and lower receptacles exclusive of the cross-sectional area of such string of tubing.
- Well treating fluids under pressure are introduced through the upper packing means to said enclosed volume where the cross-sectional areas of the upper and lower receptacles are adjusted relative to one another to have substantially equal areas thereby balancing the upper and lower areas and equalizing the upward and downward forces on the string of tubing within the enclosed volume.
- the apparatus includes a packer bore receptacle assembly which has upper and lower packer bore receptacles.
- Packer means including an upper packer sealing assembly and a lower packer sealing assembly are constructed and arranged for a sliding and sealing reception respectively in the packer bores of the upper-and lower receptacles.
- the sealing assemblies are coupled toone another and spaced-apart by a section of tubing so that when the upper packer sealing assembly and the lower packer sealing assembly are slidingly and sealingly received in the respective packer'bores that upper and lower cross-sectional areas are defined.
- the coupling of various parts herein described can be by any sectional area whereby the effective areas ofthe upper and lower cross-sectional areas are substantially equal.
- FIG. 1 is aview in vertical cross-s'ection through earth formations and a well bore, and-illustrative of wellcompletion systems according to the present invention
- v 1 FIG. 2 is a diagrammatical view illustrating acentral concept of the present invention.
- FIG. 1 a wellcompletion system is illustrated in vertical cross-section through a producing well which traverses earth formations.
- the borehole 10, which is drilled through the earth formations typically has sections ll, 12, and 13 of different diameter where the bore size decreases as the depth of the well increases.
- two horizontal zones A and B of earth formations are illustrated from which it is desired and-intended to separately and independently produce hydrocarbons or 'gas.
- a first tubular assembly which is called casing is disposed between. the earths surface and to a selected strata depth, and the annulus .15 between the casing and the borehole section 10 is cemented in a well-known manner.
- a liner 16 which is simply a tubular assembly telescopically received by the casing 14 and which extends below thecasing to a lower or deeper strata depth.
- the liner 16 is attached to the lower end of the casing by a suitable, well-known cone and slip locking arrangement 17.
- the cone and slip arrangement typically permits insertion of the liner through the casing to the desired location. Actuation of the slip and cone arrangement anchors the linerto the casing.
- the annulus 18 between the liner l6 and the borehole section 12 is also suitably cemented.
- a packer bore receptacle assembly 19 (sometimes called PBR assembly) which is a tubular assembly telescopically received by the liner l6 and which extends below the liner 16 to the bottom of the borehole section 13.
- the PBR assembly to the lower end of the liner 16.
- the hanger arrangement '20 can be hydraulically or mechanically set in any conventional manner. Likewise, the hanger arrangement can be located above or below a bore 22 of the PBR assembly 19 or can be entirely eliminated if the assembly is set on'the bottom of the hole.
- Cement is also disposed in the annulus 21 between the borehole section 13 and the packerbore receptacle assembly 19. As illustrated, when the casing 14, liner 16, and packer bore receptacle assembly 19 are installed in the borehole, the annulus from the bottom of the hole to the top of the hole is filled with cement which effectively prevents migration of gas and fluids between formations and to the earth s surface.
- a flow conduit for hydrocarbons is provided.
- a perforating device such as a shaped-charged gun (not shown) or the like, is lowered through the conduit and used to perforate the earth strata section A and the earth strata section B, either conjointly or separately so that the earth formations are opened up through perforations to the interior of the conduit.
- a packer bore receptacle assembly 19 has upper and lower packer bore receptacles respectively with bores 22 and 23 which are polished and have a uniform diameter along their lengths.
- the upper and lower packer bore receptacles are coupled to one another by a tubular casing or pipe 21A and spaced apart so that the bores 22 and 23 are arranged to strad die the earth formation strata B.
- the bores 22 and 23 may be suitably coated with teflon" or any other suitable preparation to protect the surface of the bores.
- a perforating means places the earth strata B into fluid communication by means of perforations 24 with the bore 41 of the PBR assembly 19 intermediate of the packer bores 22 and 23 of the upper and lower receptacles.
- a casing or-pipe 23A which has a bore wall tubing 28.
- the lower seal assembly 27 includes a series-of annular chevron rings of packing material 29 disposed between upper and lower back-up flanges 30 and 31. The outer diameter of the chevron rings 29 is somewhat greater than the internal diameter of the polished bore 23.
- the chevron rings 29 are sufficiently resilient to allow their compression when inserted into the bore 23 so that the compression of the chevron rings provides a resilient force and extremely tight fluid seal with respect to the internal diameter of the bore 23.
- the upper seal assembly 26 similarly includes annular chevron packing rings 32 disposed between upper and lower shoulders 33 and 34, and having an outer diameter somewhat greater than the inner diameter of the polished bore 22. In a similar manner, the rings 32 are sufficiently resilient so that they are compressed when inserted into the bore 22.
- the upper end of the upper seal assembly is coupled by a short section 35 of a heavy walled tubing string to a production tubing string which extends to the earths surface. With both sealing assemblies in the respective bores, fluids from the lower formation canbe passed to the earths surface via the conduit of the tubing.
- the lower packer bore 23 of the PBR assembly 19 includes an upwardly facing flange portion 37.
- the spacingbetween a downwardly facing bottom shoulder 31 of the lower seal assembly 27 and downwardly facing bottom shoulder 34 of the upper seal assembly 26 is made such that when the bottom shoulder 31 engages the flange 37, the upper shoulder 34 will preferably be spaced slightly above an upwardly facing flange 38 so that downward weight applied to the tubing string 36 is applied to the lower flange 37.
- the length of the packer bore 22 between its uppermost shoulder and the lower flange 38 can be from 10 to 20 feet with 10 to 12 feet being a popular length.
- the long" string which includes the tubing sections 36, 35 and 28, and the upper and lower seal assemblies 26 and 27 can be inserted through the well casing and lowered until the lower seal assembly 27 lands on the flange 37, at which time the lower shoulder of upper seal assembly 26 is just short of engaging the upper flange shoulder 38.
- the movement of the tubing string and location of the packer seal assemblies in the packer bores requires only vertical movement.
- the seal assemblies allow the use of maximum size internal diameters within the tubing string sections to handle higher volume fluids for stimulation of the earth formations.
- the enclosed volume 40 is defined by the bore 41 of the casing intermediate of the upper and lower sealing assemblies 26 and 27.
- the effective cross-sectional area for the lower seal assembly is designated by the symbol A
- the effective cross-sectional area across the upper assembly is designated by the symbol A
- the arrows illustrated on the areas indicate the direction of forces when hydraulic pressure is applied to the areas.
- the upper packer bore 22 is larger in diameter than the lower bore 23 and would ordinarily contain a larger cross-sectional area.
- the seal assembly 26 has an opening 42 extending longitudinally therethrough and the cross-sectional area of the opening is designated as A
- the area A is sized so that the effective cross-sectional area across'each of the packer bores is substantially equal.
- area A 1 is equal toarea A minus area A
- an enlarged bore 43 At the upper end of the opening 42 through the packer seal assembly 26 is an enlarged bore 43 (FIG. 1) which has an upwardly facing shoulder and which received the lower endof a tubular stinger 44.
- the stinger has a circumferential annular sealing device 46 so that when the stingeris disposed within the bore 43, a sealing relationship is made with respect to the seal assembly.
- the stinger 44 in turn is coupled to a short string of tubing 45 and can be inserted and removed by straight up and down motion.
- the lower zone can be acidized for example with hydrochloric acid, and flushed in a well-known manner.
- the upper zone that is, the zone between the upper and lower receptacles then can be treated with hydrochloric acid by pumping such acid down the short string and flushed in a well-known manner. Because the effective areasacross the packer seals are substantially equal, there is no net effect upon the seal assemblies tending to move them because the upwardly directed force resulting from the piston action on the upper seal assembly is counteracted by the downwardly directed force on the lower seal assembly.
- the'tubing string will alter its length because of temperature changes and thus the tubing can shorten.
- the length of the upper packer bore receptacle is long enough to permit the movement of the seals during the treatment.
- the long string perferably includes a section 28 of heavy 2 /8 in., 8.70 lbs. tubing between the seal assemblies, a section 34 of 2% in., 6.50 lbs. tubing to a location above the end of the casing 14, and then a string of tubing 36 of 3% in., 10.30 lbs. tubing to the surface.
- the short string can include 3% in. and 2% in. tubing with a stinger to seal in the bore 43. Both Zones A and B can then be independently and sequentially treated with acid without requiring any further equipment such as hold-downs or removal of the strings from the well bore.
- a method for completing a well traversing earth formations comprising the steps of:
- Apparatus for use in oil and gas wells which traverse earth formations comprising:
- a packer bore receptacle assembly adapted for cementing in place in a borehole, said receptacle assembly having upper and lower packer bores,
- packer sealing means including an upper packer sealing assembly and a lower packer sealing assembly, said sealing assemblies being constructed and arranged for a sliding and sealing reception respectively in said upper and lower packer bores, said sealing assemblies being coupled to one another and spaced-apart by a section of tubing so that when said upper packer sealing assembly and said lower packer sealing assembly are slidingly and sealingly received in said upper and lower packer bores that upper and lower cross-sectional areas are defined,
- said lower packer bore has a second polished uniform diameter extending between a third, inwardly extending shoulder and a fourth, outwardly extending shoulder, where said fourth shoulder is disposed above said third shoulder,
- said upper and lower packer sealing assemblies respectively having first and second sealing elements thereon, fifth and sixth downwardly facing shoulders, respectively located below each of said sealing elements, said sectionof tubing spacing, said fifth and sixth shoulders from one another so that upon engagement of the fifth shoulder with the third, inwardly extending shoulder, that the sixth shoulder is located above the first, inwardly extending shoulder.
- said flow conduit means includes an upper polished bore with an inwardly extending shoulder and a tubular member constructed and arranged for sliding and sealing reception into said upper polished bore and engagement with said inwardly extending shoulder.
