Description

BACKGROUND OF THE INVENTION

1. Field Of The Invention

This invention is directed to a control head flow diverter for a wellbore system and, in one particular aspect to a remotely controlled flow diverter whose interior apparatus is non-manually removable.

2. Description of Related Art

There are a variety of control head flow diverters in the prior art. FIG. 7 shows a typical prior art control head flow diverter F that is secured on top of a typical blow out preventer ("BOP") stack (not shown). The head F has inner mechanisms, structures and apparatus, including a rotatable spindle S whose top is connected to a kelly and whose bottom is connected to a metal ring M and a movable or collapsible seal R. Bearings B facilitate rotation of the spindle S. Bolts L and T releasably secure the internal apparatus including the spindle S to a main body A of the head F. Flow enters the head F from below through an opening O. In response to the pressure of this fluid, the seal R closes to stop flow through the top of the spindle S and flow is then diverted out an exit port E. To remove the internal apparatus from the head F, the bolts L which initially extend into a J slot on the spindle preventing its rotation are manually removed, freeing the spindle for rotation and removal. Bolts T secure various parts together. This requires personnel at the location of the head F which is usually beneath a floor of a drilling rig.

There has long been a need for an effective, efficient and easily removable control head flow diverter. There has long been a need, recognized by the present inventors, for such a control head that does not require the manual manipulation of bolts to remove the control head from a BOP stack. There has long been a need, recognized by the present inventors, for a remotely controlled and remotely removable control head flow diverter.

SUMMARY OF THE PRESENT INVENTION

The present invention, in certain embodiments, discloses a control head flow diverter with a main housing within which internal apparatus is releasably held by one or more remotely controlled mechanisms which do not require manual manipulation for release of the internal apparatus from the main housing; although such manual manipulation is possible. The internal apparatus includes a seal element (e.g., but not limited to an element like the element R in FIG. 7) for diverting flow from a typical exit up through a spindle of the internal apparatus to an alternate housing exit port.

In one aspect the internal apparatus of the flow diverter has a series of lugs that releasably enter slots in the main housing. To prevent movement of the internal apparatus to a position that allows it to be removed from a top opening of the main housing, one or more remotely controlled side cylinders mounted on the exterior of the main housing each has an end projectable into the housing and into a slot, thus preventing removal of the internal apparatus until the cylinder ends are retracted. The slot may be any desired shape and may, in one aspect, have a vertical portion and an inner communicating horizontal portion.

Upon selective retraction of the side cylinder ends, rotation of the internal apparatus is permitted to a position in which it is freed so the lugs may move upwardly in a vertical portion of the slot, and the internal apparatus may be lifted out from the main housing. One or more remotely controlled torque cylinders, in certain aspects of the invention, are on a mounting plate on which the internal apparatus is mounted and the torque cylinder(s) is/are selectively activated to rotate the internal apparatus, thereby positioning the lugs for upward vertical movement in the vertical slot portion. The or each torque cylinder, preferably, has a downwardly projecting portion that rides in a corresponding track on a plate on the main housing. When the internal apparatus is removed from the main housing, the plate with the torque cylinders remains on the main housing.

In certain aspects the side cylinder(s) and/or torque cylinder(s) are remotely controlled while in other aspects any of the cylinders may also be manually manipulated for selective removal of the internal apparatus up through the main housing.

DESCRIPTION OF EMBODIMENTS PREFERRED AT THE TIME OF FILING FOR THIS PATENT

FIGS. 1A-1F show a control head flow diverter ("head") 10 with a main housing 12 having a top opening 14, an interior 16, a side flow port 18, and a bottom opening 19.

A lower plate 22 is secured above a plate 30 to the housing 12 with bolts 24. The plate 22 has tracks 28 formed therein. A mounting plate 32 is secured on the member 26 by bolts 24. Internal head apparatus 34 is secured to the mounting plate 32 and has a spindle 59 (like the spindle S, FIG. 7) and related structures 35 that extend down into the housing 12, including a hollow cylindrical memeber 26 on the plate 22. A seal element 90 is connected to the bottom of the spindle 59 (and may be any known suitable seal element, e.g. but not limited to, that of FIG. 7). Lugs 93 project out from the spindle 59 and are movable into and out of the slots 57.

Pins 36 extending through holes 38 in the plate 32 into corresponding holes 42 in the cylinders 60 to secure the plate 32 to the cylinders 60. Locking cylinders 50 in protective shrouds 52 are mounted on the sides of the housing 12. Rods 54 of the cylinders 50 project through the housing 12. As shown, the slots 57 have a vertical portion and a lower horizontal portion into which lugs 93 are movable.

As shown in FIGS. 1A and 1B, torque cylinders 60 are movably mounted between brackets 62 which are secured to the plate 22 and the member 26 with the lower projections 44 of cylinder ends 13 movable in the tracks 28 of the plate 22.

FIG. 6C shows a mounting bracket 67 for the shrouds 52. FIG. 6D shows a plate 91 used with the bracket 67.

FIG. 8 shows schematically a control system 70 for the side cylinders 50 and the torque cylinders 60 with a suction strainer 71, a pump/motor subsystem 72, a two-position safety valve 73, a return filter 74, a relief valve 75, a three position directional valve 76, sequence valves 77 and 78, a fluid level gauge 79, a vent 80, a fluid reservoir 81, and optional flow control valves 82 which maintain the same pressure in the torque cylinders so that they apply a balanced force. Known fluid flow lines and hoses are used between the various components of the system

In one method of operation of an apparatus 10, controls, valves, and flow lines etc. of the system 70 are used. The pump/motor subsystem 72 provides and maintains pressurized hydraulic fluid pumped from the reservoir 81 to various flow lines and system components. The relief valve 75 is set at a suitable predetermined pressure. Initially the spindle and internal apparatus 34 is locked in place (as in FIG. 1F). To remove it from the main housing 12 (e.g. to "trip" out of the wellbore), the valves 73 and 76 are actuated (using, in one aspect, a control console CC remote from the system 10) so that pressurized hydraulic fluid flows to retract the ends 54 of the locking cylinders 50 (as in FIG. 1A). Fluid also flows to the valve 77 which prevents fluid, initially, from flowing to the torque cylinders 60. When fluid flow to the valve 77 reaches a predetermined pressure, pressurized fluid flows to the torque cylinders 60, extending them (as in FIG. 1A) and thereby rotating the mounting plate 32 and the internal apparatus 34 connected thereto to an unlocked position (as in FIG. 1E). The internal apparatus 34 can then be removed, e.g. with a line, drill string, or cable connected to lifting eyes 84. The pins 36 are not secured to the cylinder ends, but are movable in the holes therein and therefrom.

To reinstall internal apparatus 34, it is positioned above the main housing 12, the pins 36 are aligned with the holes 42 in the cylinder ends 13, and it is then moved down so that the pins 36 enter the holes 42 and the internal apparatus 34 then moves down within the main housing 12 of the flow diverter 10. Valves 73 and 76 are actuated and fluid flows to retract the cylinders 60 moving the apparatus 34 so that the ends 55 can be moved inwardly in the slots to block movement of the lugs 93. At this time fluid flows to the valve 78 which prevents the fluid from flowing to the locking cylinders 50 until a predetermined pressure. Then the locking cylinders 50 are actuated when sufficient fluid pressure is applied to and through the valve 78 to actuate the locking cylinders 50 and to thereby lock the internal apparatus 34 in place.

FIGS. 9A-9C show another embodiment of a system 100 according to the present invention which is like the system 10 (and the same numerals for the system 100 indicate the same parts as in the system 10), but with an entry guide 102 having slots 104 for guiding the pins 36 into the holes 42 in the cylinder ends 13.
