CONT-ROLLING APPARATUS FOR DRILLED WELLS Application led September 23, 1931..

My invention relates to`controlling apparatus for drilled wells and more particularly to such devices which are used -for capping said well, such as oil, gas or water wells, which are usually ditiicult to close because of heavy gas pressures encountered at deep horizons, and when unable to close, resulting in exceedingly heavy damage, to the well and the surrounding properties, further, in case of violent overflow, such well is very difficult to bring under control, or when on fire, in many instances such a well must be left burning, until the gas pressure subsides.

It accordingly is an object of my invention to provide a simple means of capping a well, when it is coming-in, to withstand the heavy gas pressure, which at times exceeds 1000 pounds per square inch, and also to withstand the acute corrosive and abrasive ac tion caused by sand and mud being forced through the connections, under such a pressure.

A further object of my invention is to provide safety means, which may be if desirable, associated with the well casing, thus preventing gushers to spout the liquid emanating from said well all over the ground, and lconsequently preventing the blow-out, reducing the fire hazards, providing the positive control during all drilling operations, also easy and safe casing capping.

An other ob]ect of my invention is to provide safe and simple means forworking upon the well when under pressure or lowing, whereby the so called Christmas tree apparatus may be easily attached to said well casing, which is for the purpose of divertingthe fluid from said well into pipe lines or tanks, as the case might be.

Further objects and advantages as will hereinafter more fully appear, I attain by the construction described in the specification and illustrated on the drawing, forming a part of my application.

Reference .is had to the accompanying drawing in which the similar reference characters denote similar parts.

Describing my invention more in detail, said invention comprises of a capping apparatus which is connected to the well casing having the top capping members in position,

ready foi` instant use, mounted upon guides or rails, and equipped with a shut-olf valveand the by-pass passage, equipped with the' control valve.

The shut-off valve, is arranged in such a manner, whereby the Huid tubing may be easily manipulated, extended or taken out of said casing, having a head attached to the last section of said tubing, to which the Christmas tree apparatus is attached, and which is held in position, upon the head casing by means of the self adjustable clamp.

More particularily said invention comprises of a head casing 2, which is attached to the pipe casing 3, positioned under the derrick platform 4, supported by columns 6; the pipe casing 3, is connected permanently to the male flange plate 8, having dove-tail sides 10, and adapted to receive the female ange plate 12, of said head casing 2, which is guided in place by means of angle guides 14, and having the body 16, equipped with an opening 18, which may be if preferred, associated with a control valve 20, to divert the flow of the fluids Within said head casing 2.

The upper section of the body 16 of said casing 2, is also equipped with a valve seat 22, which is to receive the valve plate 24, which is hinged as at 26 and held in place by means of a shaft 28, keyed as at 30, having the packing gland 32 and the plug 34, associated therewith to prevent the leakage, also said shaft 28, is connected to a wheel 36, which is used for manual operation of said valve plate 24; and for emergency, I have equipped said valve plate 24 with a set of springs 38, which are for the purpose of closing the well automatically, in the event sudden pressures are encountered, thus preventing blow-out and fire.

The male plate 8 and the female plate 12, are also equipped with a latch 40, shown in Figs. 1 and 4, respectively, which is controlled by means of a line 42, and which may be of I any desired length in practice most adaptable; slidin said plate 12 over said plate 8, is accomplis ed by means of aline 44 attached to the hook 46 and operated by means of a winch 48, preferablypositioned at a safe distance of the well (see Fig. 1.) and when said plate 12 is in position, the latch 40 in place, held tight by means of the line 42, then the bolts 50 are being placed in sockets 52, tightened by means of nuts 54, and in the meantime the valve 20 may be opened to relieve the pressure within said well, and said valve plate 24 held in seat 22 by means of springs 38 prevents said fluid under pressure froml emanating upwardly.

When the well is capped, the next main operation is to place within the well casing 3 the fluid tube 56 comprising a plurality of sections and the screen, not shown) and to the last tube section 56 I ave connected a locking head 58, adapted to receive a nipple 60 to which the male flange plate 8 may be attached and which is slideably associated with the female flange plate 12 as hereinbefore described.

Said male plate 8 may be, if desirable, equipped with a gear rack 62 held in mesh with a gear 64, which is mounted upon .a bearing 65 of the female plate 12, having a ratchet 66 and the pulley 68 associated therewith, and operated by means of a line or chain 70 which extends a considerable distance from said well, or it may be attached to the columns 6 as shown. (Fig. 1.

The plate 12, is connected to the Christmas tree apparatus 72 (shown in dotted lines Fi 1.) and is held in position by means of guides 74 and the hangers 76; (see Figs. 1, 2 and 4).

Said locking head 58 and the upper body section 16 of the casing 2, isprovided with the tapered sections 78 and the straight cut sections 8O which are adapted to receive the clamp 82, made of two parts, which is hinged as at 84 and held in place by means of locking bolt 86, as shown.

Vhen desirable, said nipple 60, may be connected to a standard flange connection 8S and the Christmas tree apparatus 72 may be connected to a flange 90, which is slideably positioned upon a circular track 92, thus permitting said apparatus 72, to be easily located over the flange connection 88, and locked in position.

While I have thus described my invention with great particularity, I wish 1t to be understood that the same is only illustrative and may be modified throughout a wide ral e; I accordingly do not propose to be limite to the exact details of construction shown and described, but reserve the right in practice to make any and all modifications which may come within the scope of the appended claims.
