4 This invention relates to oil well drilling equipment for use under water.
It is an object of the present invention to provide an apparatus for use in drilling wells under water and particularly for reworking wells after the original drillingrig, derricks and the like have been removed and which can be readily floated to the location of the well, easily submerged over the well and as distinguished from the usual drilling equipment will withstand high winds and waves.
Another object of the present invention is to provide oil drilling equipment adapted for use under water which has adequate working space and wherein the lowered ballast tank has derrick equipment attached to an upper ballast tank by which the lowered ballast tank over the oil well can be hoisted vertically so that the tower will be extended upwardly through the upper ballast tank and the equipment conditioned for transport and location over another well site.
Other objects of the present invention are to provide undersea oil well drilling equipment which is of simple construction, easy to transport and install, of durable and sturdy construction, and efllcient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is an underwater elevational view of the equipment installed over an oil well site.
Fig. 2 is a cross-sectional view of the enclosure equipment taken on line 22 of Fig. 3.
, Fig. 3 is a top plan view of the enclosure "equipment looking into the upper end of the vertical pipe and upon the top faces of the ballast tanks, the view being taken generally on line 3-3 of Fig. 2.
Fig. 4 is a transverse cross-sectional view taken on line 4-4 of Fig. 2 and looking in the direction of the arrows thereof.
Fig. 5 is an enlarged fragmentary and crosssectional view, in elevation, taken on line 55 of Fig. 2 and showing the safety chambers.
Fig. 6 is a transverse cross-sectional view taken on line 66 of Fig. 5.
Fig. 7 is a transverse cross-sectional view of the slush pit and taken on line 'l-| of Fig, 8.
Fig. 8 is a cross-sectional view, in elevation, of the slush pit taken on line 8-8 of Fig. I.
Fig. 9 is a fragmentary and cross-sectional view of a hose fitting used in connection with the lowered ballast tank adapted to be submerged and rested upon the bottom of the sea over an oil site and through the bottom of which the drilling, cleaning and other operations are performed. To gain access to the bottom land, there is provided a trap door 22 which can be lifted to expose the land surface or a previously formed oil well where the equipment replaces the original drilling rig. Fixed to and extending upwardly from the lowered ballast tank 2| is a large pipe 23 providing a caisson which is formed in sections connected together and added one above the other as the ballast tank 2|. is submerged and lowered from upper ballast tank 24. Both of the ballast tanks are of ring formation and the upper ballast tank 24 may fit the interior of the lower ballast tank. In the bottom of the lower ballast tank are two winches 25 and 26 connected respectively by their ropes 21 and 28 with the bottom of the upper ballast tank at opposite sides of the pipe 23. The winches 25 and 26 are supported at one end upon a bearing block 29 and upon the other end by a bearing sleeve in the lower end of the pipe 23. Within the bottom of the pipe 23 is a detachable driving gear element 32 which is connected through face plates 33 with the winches and can be removed after the ballast tank 2| has been properly located over the oil well site. A driving motor 34 with a pinion 35 serves to drive the element 32. This equipment can likewise be removed from its location to provide adequate working space at the bottom of the pipe 23.
In the bottom of the pipe 23 is a door 36 which enters a safety chamber 31, Figs. 5 and 6, which is air conditioned and which will provide an escape for workmen should large volumes of gas be let loose from the well. A hose 38 connects this chamber 31 with the surface of the water and by means of this hose air or oxygen can be pumped to the chamber. To give double assurance to the workmen, asecond chamber 39 is provided on the end of the chamber 31 and access is had to it through a door 40. This chamber 39 is likewise connected to the surface by a hose 4|. This chamber 39 has an escape door 42 through which the workmen may take to the water or leave the chamber 33 when the ballast tank is raised to the surface. Likewise the workmen may enter the bottom end of the pipe 23 by way of the escape doors. Other access and egress is had with the lower end of the pipe 23 from the opening in the top of the pipe as indicated at 43. or side doors 44 by way of a ladder 45. The ends of the pipe sections 23 at the openings radially inwardly flanged as indicated at 46 so as not to interfere with the sliding movement of the pipe 23 through the upper ballast tank 24. The flanges 45 are connected together in a watertight manner by bolts 41.
With the lowered ballast tank raised, the tanks and the pipe are easily floated to the oil well site. Thereafter the lowered ballast tank is dropped to the bottom by releasing the winches 25 and 26 and by causing the ballast tank 2! to take on water in its annular chamber 48. The pipe 23 is slid downwardly through the tank 24. The ballast tank 2! has a double bottom surrounding the pipe 23 into which water from the chamber 48 is extended as indicated at 49. The chamber 48 is connected by an airline 5| to a supply boat 52 standing by as indicated in Fig. 1.
Also working with this equipment is a slush pit barge 53, Figs. 1, '7 and 8, having a slush pit opening or chamber 54 and air chambers 55 and 56. The air chambers 55 and 56 are disposed at opposite ends of the barge and are connected respectively by air holes 51 and 58 to supply boat 52. Valve fittings 59 are connected to the air chambers 55 and 56 through which air and water can be extended at times of submerging and raising the barge 53. Hose connections 61 and 62 extend between the slush pit 54 and the pipe 23. The slush pit has fittings 63 at the side of the barge for supporting the hose 6| and 52. The connection of the hose with the pipe 23 is usually efiected after the pipe has been submerged and by a diver working under water. In Fig. 9 there is shown a specially formed fitting 65 which the diver uses for connecting the hose 6i and 62 to the pipe 23. This fitting 65 has internal threads 56 adapted to receive a plug 51 which will be accessible to the workmen within the pipe 23 after the fitting has been secured to the pipe by an annular internally threaded coupling member 58. Adequate pumping equipment can be brought to the lower end of the pipe 23 for extending the slush to the slush pit 54.
As the well is being worked, pipe casing 69 is extended down through the pipe 23 and into the well. After the well has been finally formed a head arrangement, as shown in Figs. 10 and 11, is formed thereover. The oil pipe through which the oil is brought to the surface lies internally of the casing 69 as indicated at H and is brought upwardly therethrough to have adequate outlet fittings 12 connected thereto. Over the land surface there is disposed a bottom piece I3 which has a central opening 14 through which the casing 69 extends. A packing member 15 is secured to the plate 13 and is filled with packing material 16 which is retained therein by a pressure plate TI. On the top of the casing 89 there is supported a base 18 on which can be placed a cover 19 to keep out seawater from space surrounding the fittings 12. This base is formed to receive packing material 19 and a pressure plate 8|.
With the fitting arrangement established a cement form 82 is secured to the plate 13 by bolts 83. Concrete 84 is then poured through the upper end of the cement form and allowed to set about the packing parts surrounding casin: 63 and about base It.
Ill)
It should now be apparent that there has been provided simple equipment for handling oil wells under water and that this equipment is portable. easy to install and provides adequate space and safety for the workmen.
