Definitions
- the technical field of the invention is downhole tools and methods for employing downhole tools in oil and gas wells,
- Oil and gas wells are drilled at greater depths than in the past. Extended reach wells may he drilled several miles into the earth, with a large portion of the wellbore oriented in a direction that deviates substantially from the vertical direction.
- the operation of drill strings and other tubular devices with attached downhole tools at great distances within a deviated wellbore provides significant challenges in the drilling industry.
- Sand control screens are employed in wells such as extended reach wells to inhibit entry of sand and other solid particles into the wellbore while at the same time facilitating entry of oil and gas. Screens of this type comprise a considerably heavy mass. Screens may be employed in very long sections that extend as much as one mile in length. The total weight of a screen thousands of feet in length is substantial.
- the factional forces generated between the screen and the wellbore during placement of such screens into extended reach horizontal wells poses a significant technical and mechanical challenge. In the placement of such screens, it is necessary to apply a force to the screen that overcomes the frictional forces resisting screen placement. When a wellbore deviates substantially from the vertical direction, it becomes a challenge to generate sufficient forces downhole to move the screen into the desired position within the well.
- This invention is directed to apparatus and methods useful for placing components of any type into a well. And, in one particular aspect of the invention, the invention is directed to apparatus and methods for placing sand control screens into weiibores.
- an apparatus is adapted for insertion of a component into a well having a cased hole section.
- the apparatus comprises a tool member adapted for receiving a wellbore fluid and an engagement mechanism mounted upon the tool member.
- the engagement mechanism may be configured for selective factional engagement to the cased hole section of the well.
- a piston is provided haying a first end and a second end connected to the tool member.
- the piston is configured for axial extension relative to the tool member.
- a first choke may be attached to the piston, the first choke being configured for receiving pressurized fluid and transmitting fluid force to the piston to extend the piston axially relative to the tool member.
- the apparatus includes an engagement mechanism with a slip.
- the slip is configured for movement between an inboard disengaged position and an outboard engaged position, wherein the outboard engaged position affords fractional contact between the engagement mechanism and the cased hole section to secure the tool member relative to the cased hole section.
- the apparatus may include an attachment mechanism upon the second end of the piston.
- the attachment mechanism may be configured for releasably securing the component to the piston of the tool member,
- a first choke may be removably secured to the tool member.
- the tool member may be configured for receiving additional chokes with different fluid flow characteristics.
- a force cone may be employed for receiving pressurized wellbore fluid and transferring force to the slip to actuate the slip to the outboard engaged position.
- the invention may be directed to a method for inserting a component into a well using a drill string with a tool member secured to the drill string.
- the well may have at least one cased hole section.
- a drill string is provided with an attached tool member and piston and a component secured to the distal end of the piston .
- the drill string is lowered into a cased hole section of a well.
- a fluid is pumped through the drill string to the tool member. Fluid pressure is applied to the tool member that forces, with fluid pressure, an engagement mechanism of the tool member into frictional contact with the eased hole section.
- the tool member is secured relative to the cased hole section of the well. Fluid is forced through a choke attached to the piston to generate force upon the piston.
- the piston is extended axially relative to the tool member, thereby inserting the component into the well.
- the fluid pressure may be reduced, which releases the engagement mechanism from factional engagement with the cased hole section.
- the drill string is lowered further into the well. This assists in returning the piston to a retracted position within the tool member.
- This procedure of raising pressure, followed by reducing pressure and lowering the drill siring may be repeated as many times as needed until the component (i.e. screen, perforating gun, or other device) is positioned correctly in the well, in the case of a screen, it is possible to release the screen from the piston in the proper position for well production through the screen.
- fluid pressure may be applied to the cone, the cone being configured for receiving pressurized fluid and transmitting force to the slips.
- the slips are engaged against the cased hole section of the well.
- a spring is applied to the cone and the spring is compressed during the application of pressure to the cone. The spring is relaxed upon reduction of fluid pressure to the cone.
- the screen may be released by rotating the drill string, thereby disengaging the screen. This may be accomplished, for example, by employing left-handed threads at threaded connection 58, as further discussed herein. In other applications, it may be possible to release a component, such as a screen, by applying elevated fluid pressure to break a pressure activated rupture disk, thereby releasing the component from the tool member. Other methods known in the art for releasing a component from a drill string could be used as well.
- any commonly used oilfield fluid can be employed for the application of fluid pressure in the invention, including for example, brine, hydrocarbon, water based mud, oil based mud or pseudo-oil based mud.
- a fluid loss additive that is pumped with the fluid into the welibore, through the choke, and into the formation.
- the fluid loss additive may be selected from essentially known and effective additive, including hydroxy ethylcellulose (HEC) polymers, xantham gums derived from a strain of Xanthomonus campestris (XC), polymers having sized solids, and also degradable solid polymers.
- Such a fluid loss additive may include as well calcium carbonate or a calcium carbonate-containing additive.
- the invention may be particularly useful to resolve fluid loss problems by the use of fluid loss additives, which may be transported through the choke and into the subterrenean formation.
- the ability to pump fluid loss additives during the depl oyment of the component into the welibore is a significant advantage in the use of the invention.
- FIG. 1 shows the tool member in a welibore
- Fig. 2 illustrates a longitudinal cross-section of the tool member in the compressed or "run in” condition
- Fig. 2A shows a close-up cross-sectional view of the engagement mechanism in the disengaged position
- Fig. 2B shows a close- up cross-sectional view of the engagement mechanism in the engaged position
- FIG. 3 illustrates the tool member as it is receiving fluid pressure, with the engagement mechanism contacting the casing of the welibore and the piston beginning its axial extension (stroke) relative to the body of the tool member;
- Fig. 4 shows the piston of the tool member in the extended position
- Fig. 5 illustrates the engagement mechanism in the disengaged position with the entire string being pushed further into the wellbore, thus contracting the piston to a return position within the tool member
- Fig. 6 shows a later step which occurs after multiple "jacking" procedures into the well, wherein the screen is now residing at the desired position for screen placement, and the tool member is uncoupled from the screen and ready for retraction from the wellbore.
- an apparatus and method for insertion of a component into a well.
- the component may be a gravel pack screen, perforating gun, or other mechanical device.
- the invention may be applied to insertion of such a component into shallow reservoirs with relatively long well sections that deviate from vertical.
- a swiveling tool may be applied between the drill pipe and the tool member.
- a swiveling tool could function to facilitate the rotation of the deployment string without rotating the tool member and screen.
- a swiveling tool is the Caledus
- SwivelMASTERTM manufactured by Caledus UK Ltd of Aberdeen, Scotland, which is a drill pipe deployed tool to aid sand control screens or liners to be run at high angles or in tortuous wells to achieve the required depth.
- a drill pipe 26 is extended into a wellbore 24 inside a casing 22 below the ground 28 (or below the mudline in the case of a well drilled into a body of water).
- a tool member 20 is attached to the drill pipe 26, and also includes a packer 30.
- a component such as a screen 32 is connected to the tool member 20.
- Fig. 2 shows a longitudinal cross-section of the tool member in the compressed or "run in” condition.
- the drill pipe 26 is secured by empaded connection 34 to the body 36 of the tool member 20.
- a force cone 42 is held by spring 40 in an open position, which allows the slip 38 to remain in the disengaged position (i.e. not in contact with the casing 22).
- Fluid cavity 48 contains pressurized fluid which acts upon the force cone 42 as farther described herein with reference to Fig. 2A.
- a choke retaining nut 44 secures choke 46 within the piston 50.
- Piston 50 is secured by threaded connection 52 to joint 56, which in turn is connected by threaded connection 58 to screen 32. Piston 50 rests against the stop 54 of the body 36.
- the axial direction is indicated by direction 60 in Figs. 2-5.
- the description set forth herein for numbered components in Figs, 2-5 apply equally to each of the Figs. 2-5, and like numerals are used for like structures.
- Fig. 2A reveals a closer view of the slip 38 in the disengaged position (as in Fig. 2). Fluid from fluid cavity 48 enters inlet 62 into vesicle 64 where it may apply force upon force cone 42. In Fig. 2.4, the pressure is low, so that the force cone 42 is held in its relaxed position by spring 40. The base 66 butts against force cone 42. A spring 68 is also in the relaxed (not sprung) position against grip plate 70, Grip plate 70 is not engaged with casing 22 in the configuration of Fig. 2 A, which facilitates the run in of the tool member 20 into the wellbore 24.
- Fluid pressure causes piston 50 to move in the axial direction 60 into the wellbore 24, which carries the screen 32 into the wellbore.
- Fig. 3 shows the position of the piston 50 as the piston 50 begins its descent into the wellbore 24, as exhibited by space 55 (see Fig. 3) which begins to form between the piston 50 and the stop 54.
- Fig. 4 shows further descent of the piston 50 and screen 32 into the wellbore 24.
- the piston of the tool member 20 is in the fully extended position, with piston 50 resting against stop 54.
- the screen 32 lias been pushed with considerable force into the wellbore 24 in Fig. 4.
- Fig. 5 illustrates a farther step in the sequence, wherein the fluid pressure has been reduced, causing the force of the spring 40 to relax, pulling the base 66 from the grip plate 70, facilitating the release of frictional engagement of the grip plate 70 from the casing 22. Then, in a next step, the drill pipe 26 is lowered into the wellbore 24 by a distance that approximates the length of the piston 50, which pushes the piston 50 back into the body 36 of the drill pipe 26, as shown in Fig. 5.
- a packer 30 may be set against the casing (see Figs. 5, 6), and then the threaded connection 52 may be rotated to release the screen 32 as shown in Fig. 6,
- the perforating gun would not be released, but would be retracted from the well with the drill pipe 26 once perforation operations are completed.
- the screen may be released by rotating the drill string, thereby disengaging the screen, as shown in Fig. 6. This may be accomplished, in one embodiment of the invention, by employing left-handed threads at threaded connection 58, wherein the rotation of the drill pipe 26 facilitates the release of screen 32.
- it may be possible to release a component, such as a screen by applying elevated fluid pressure to break a pressure activated rupture disk (not shown), thereby releasing the component from the tool member.
- Other methods known in the art for releasing a mechanical component from a drill pipe 26 could be employed in the practice of the invention.
- a fluid loss additive may be added to the fluid and provided through the choke 46 for deployment into the formation. This may assist in blocking fluid loss into the formation. It is one advantageous feature of the invention that a fluid loss additive may be provided through the apparatus and into the formation during the deployment of the apparatus into the wellbore.
- the additive may be selected from essentially known and effective additive for oilfield use.
- Such additives may include hydroxyethylcell ulose (HEC) polymers, xantham gums derived from a strain of Xanthomorms campestris (XC), polymers having sized solids, and also degradable solid polymers. Such sized solids may include calcium carbonate or salts.
- HEC is a known polymer that is used in gravel pack fluid systems.
- XC polymers are known for having good gel strength.
