Definitions
- the present invention concerns running and cementing pipe in subsea formations and, in particular, running and cementing in the subsea floor the first pipe string (structural pipe) run in an offshore well drilling operation.
- a temporary guide base is lowered on guide lines from the surface of the water and placed on the ocean floor.
- An opening through the center of the guide base is positioned over the site of the well to be drilled and serves as a re-entry means to the well site.
- a string of drill pipe having a drill bit on the lower end thereof is then lowered through the opening in the guide base and a hole is drilled into the ocean floor to the setting depth of the structural pipe string.
- the guide lines are used to guide the drill string to the opening in the guide base.
- the drill pipe is removed from the drilled hole to the water's surface.
- Structural casing is then lowered through the opening in the temporary guide base and into the drilled hole, guided by the guide lines, on drill pipe by means of a suitable running tool connected to the lower end of the drill pipe and releasably connected to the structural casing.
- a permanent guide base is attached to the upper end of the casing pipe.
- the present invention overcomes these problems by allowing the structural casing string to be cemented in place prior to releasing it from the drill pipe running string thereby eliminating the need for drilling a hole prior to running the structural casing string. Further, the invention eliminates the need for running a temporary guide base. This feature makes this invention also advantageous for use in normal, firm bottom water locations. Considerable rig time is saved by eliminating the running of a temporary guide base when running pipe in either type location.
- the apparatus for running and setting large diameter (structural) pipe in accordance with the invention includes a jet shoe which is connected into the end of the large pipe.
- the shoe comprises a cylindrical member which contains an inner receptacle provided with an upper seat, a polished bore, a check valve and a chamber.
- a plurality of open-ended jet tubes connect to the chamber at their upper ends and extend to the lower end of the shoe at their lower ends.
- Nozzles are located in the ends of the tubes which are arranged to facilitate washing formation away from in front of the shoe to form the hole for the large pipe.
- the receptacle and the tubes are cemented in place in the shoe with the upper end of the receptacle and the lower end of the tubes forming continuous flow paths through the valve.
- a stinger sub is connected to the lower end of a smaller diameter (drill) pipe.
- the stinger contains seals, is insertable into the receptacle and seals off against the polished bore of the receptacle.
- the smaller pipe also contains a closure member which re leasably and sealingly engages the upper end of the larger pipe string.
- a permanent guide base is also connected to the upper end of the larger pipe string.
- the smaller pipe also contains a bumper sub, a telescoping section, for spacing-out purposes.
- the clo sure member may be provided with an opening to which a hose is connected for measuring at the surface pressures within the larger pipe.
- the method in accordance with the invention includes the steps of lowering the larger pipe string on the smaller pipe string from the water's surface to the ocean floor and pumping fluid through the smaller pipe string and out through the jet shoe connected to the lower end of the larger pipe string while lowering the pipe strings until the predetermined setting depth for the larger pipe string is reached. Cement slurry is then pumped through the smaller pipe string and the jet shoe to cement the larger pipe string in place. The smaller pipe string is then disconnected from the upper end of the larger pipe string and removed to the water's surface.

- Fig. 9A is a vertical cross-sectional view of the uppermost end of the structural casing showing the drill pipe and closure member arranged within the structural casing and a permanent guide base attached to the upper end of the structural casing;
- Figs. 10, 11 and 12 illustrate the steps of running and cementing the structural casing in the ocean floor.
- Figs. 1 and 2 illustrate a jet shoe 10 formed by cylindrical housing 10a which contains an inner centrally located tubular receptacle 11, the inside diameter of which forms a polished bore 12.
- the upper end of receptacle 11 forms a seat 12a.
- the lowermost end of receptacle 11 forms an outlet chamber 13 containing openings 14 to each of which is connected a jet tube 15.
- the tubes are preferably arranged in a concentric ring pattern.
- the tubular receptacle and tubes are maintained in place by cement 10b.
- Three of the outer ring tubes 15a are curved to a vertical end and three of the outer ring tubes
- each jet tube 15 con tains a nozzle 16 which is insertable and held in place by a snap ring 17.
- Receptacle 11 also contains a back pressure ball check valve 18. The ball seats on a seat 19 to close off upward flow of fluids through the valve.
- the lower end of a drill pipe 25 is threaded into a drill pipe sub 26 which is provided with a stinger 27 shown positioned in receptacle 11.
- Stinger 27 is provided with a series of spaced-apart seals 28 which seal off against the bore 12 of receptacle 11.
- the upper end 30 of a structural casing pipe 31 contains a plurality of J-slots 32 spaced about the inner wall of upper end 30 of the structural casing pipe.
- 35 includes a cylindrical member 36 containing spacedapart lugs 37 which are engageable in J-slots 32 of the structural casing pipe.
- Tubular members 38 and 39 connect into the drill pipe on each side of closure member 36.
- Tubular members 38 and 39 and bore 36a of member 36 form a continuous passageway. Seals 35a are arranged on the outer surface of closure member
- Jet shoe 10 is connected, preferably welded, to the lower end of structural casing 31, as indicated at 41.
- Drill pipe 25 includes a conventional bumper sub 25a to permit proper spacing out of the drill pipe between closure member 35 and s t inger s eat 12 a .
- a permanent guide base is mounted on the upper end of casing 31.
- Housing 10a may be a thirty inches outside diameter cylinder for use with a thirty inches outside diameter casing pipe 31.
- the tubes are preferably one and one quarter inches outside diameter.
- Six of the tubes are positioned on an eighteen inch bow circle at sixty degree spacing.
- Three of the tubes 15a on the eighteen inch bow circle are vertical and the other three tubes 15b are angled at thirty degrees (A 1 ) from vertical.
- Three of the tubes 15c are on a ten inch bow circle at a one hundred and twenty degree spacing.
- the tenth tube 15d is at the center of the shoe.
- the three tubes on the ten inch bow circle are angled at twenty degrees (A 2 ) from vertical.
- the three tubes on the ten inch bow circle are in line with the three tubes at thirty degrees on the eighteen inch bow circle.
- the center tube is vertical.
- the jet nozzles are typical, snap ring type nozzles and are inserted into one and one quarter inch diameter aluminum tubing flow paths. All of the aluminum flow paths are connected to the main flow path of the shoe in chamber 13 at or below the center line of the valve 18.
- the outlets of the six tube ring are on a nine inch radius R 1 circle.
- the outlets of the three tube ring are on a five inch radius R 2 circle.
- the outlet diameter D 1 of nozzle 16 is preferably one-half inch. All of the internal flow paths for this illustrative embodiment of the invention are rated for at least three thousand psi working pressure.
- the side of the jet shoe extends approximately two inches below the cement and outer tube ends.
- the overall length of the shoe may be 59 inches.
- the cement 10b in the jet shoe is tapered at its upper end to facili tate entry of stinger 27 of the drill pipe. All of the materials in the jet shoe are readily drillable.
- jet shoe 10 is welded to the lowermost joint of the casing string. After all of the casing joints have been connected, the string of drill pipe 25 is run inside the casing string until stinger 27 has been stabbed into receptacle 11 in jet shoe 10. Casing string 31 is kept filled with water to balance hydraulic pressures and prevent collapse of the casing string. Closure member 35 is made up on the top of the casing string 31 by engaging lugs 37 in J-slots 32. Hose 42 connects to opening 40 and extends to the water's surface for monitoring pressure inside casing 31 during jetting to detect possible leaks of drilling fluid through the bumper sub seals and/or seals 28 ori stinger 27.
- Permanent guide base 45 is connected to the top of the casing string 31 and the casing string is lowered on drill pipe 25 to the ocean floor.
- Guide lines 55 are connected to guide posts 56 which are mounted on guide base 45.
- the casing string is jetted through the unconsolidated formation sediments by pumping drilling fluid down the drill pipe and through jet nozzles 16 in tubes 15 as shown in Fig.
- the invention eliminates the shallow hole instability problems in soft, unstable ocean floor deep water locations and saves significant amounts of tangible and intangible drilling costs.
- the invention is applicable in soft bottom, locations with shallow hole instability problems and, in addition, is applicable to normal, firm bottom locations as an alternative to running a temporary guide base. Eliminating the temporary guide base saves rig time. While the invention has been described and illustrated with respect to running and cementing well pipe and, particularly, structural casing pipe it has other applications, as for example, it may be used inrunning and cementing pipe used as subsea pilings. Also, other tube patterns may be employed. For example, seven tubes, instead of ten tubes, may be used in which six outer tubes are on an eighteen inch bow circle and are angled to provide internal flow paths at forty five degrees from vertical. The seventh tube is a vertical center tube.
