SU3355A1 - Method and device for collecting oil products thrown out by fountains and extinguishing them in case of fire - Google Patents

Description

The proposed invention aims to dispose, if possible, when a fountain is drilled from a borehole, products thrown out by it and not resorting to violent measures, like throwing a well with sand and stones, to tame the fountain stream without interrupting its debit, and at the same time eliminate possible The causes for the occurrence of a fire. The proposed method of collecting petroleum products thrown out by the fountains consists in enclosing the flowing well in an air-impermeable drilling rig, which is equipped with a device for withdrawing products. The proposed device turns a drilling rig into. a vessel with impenetrable walls, connected with a bore and, above all, a receptive material, absorbable by a fountain of which, the material gradually, when filling the LINE, forms: a hydrostatic pillow,

drowning jet of the fountain, at which it is done gradually and smoothly, without jolts, violating the correctness of the outflow of oil from the well.

FIG. 1 shows a vertical axial section of a drilling rig and a well in a plane perpendicular to the direction of the working drive; FIG. 2 is the same along the drive; in FIG. 3 is a plan of the drilling rig and its top view and in FIG. 4 shows a section along AA of FIG. 2 and the plan of the working floor (the position of the balancer is indicated before and after preparation: the tower for well flow). FIG. 5-7 shows the proposed modification of the device, namely: in FIG. 5 is a plan of the working floor P with a borehole, an engine room M and a boiler room K (O-window); FIG. , 6 is a front view of the Hia of FIG. 5 (3-gadget. O: -windows), and in FIG. 7-section of the oil rig and well along the drive (5 - tower, b - block for rods, 8 - valve. 9 - pipe, 72 - tower hole, 13 - part of balance bar).

The well is laid in a hole, the bottom and sides of which are riveted of sheet iron; in the center of it; there is a xc-mut 2 with casing liners and a shaft tube 3; at the ground level, the well of hole 7 is fastened with a frame of beams 30, on which a light seed field is placed for working on a key. In the walls of the well, closer to its top, there is an opening 4, from which a pipeline (not shown) extends to the settling basin, normally blocked by a breakdown at the settling basin. Outside the perimeter of the well / beam 30 are connected by a crown 3L forming a crown of the working floor of the oil rig. On this crown are the pillars 29, connected by a superstructure of beams 28, in the center of which the tower itself rises: a tower1 5 of the required height. In the cross-section, the bottom of the tower corresponds, with a certain omission, to the shape of a well 7; and in the vertical direction, the bottom is this prismatic to a certain height, further the tower is narrowed up by the Pyramid of the Cusps. Inside the prismatic part of the tower 5 is suspended, with a gap, a prize, a matte box 27, open at both ends; lero sizes must fit exactly the size of the well. The lower edge of the 27 is planed and: when lowered, it enters the groove 23 around BeipxHero, cutting the walls of the well. Along the upper edge of the box 27 t is the outer, facing downward edge of the rim 25, which, when lowered, falls into the inner groove 26, has along the bottom edge of the tower 5. Height of the box; 27 strictly corresponds to the distance of the lower edge of the tower 5 from the upper edge of the well. Box 27 is suspended inside the prismatic part of TOWER 5 on tal by means of m ropes or chains, which are dispensed from the machine hut (not shown). tower 5 is provided with a unit 6 for pulling the rods and other works; under the unit, for the maintenance of it, there is easy clearance of the regiment 7; above the unit, the tower is closed by the double valve 6. Outside, starting from the very top of the tower 5 and up to the upper structure 25 down, there is no drain pipe 9. communicating with the inside of the tower through the windows 72 at different levels locked by corresponding gate valves 32. topping 28, laid in the ground and leading to the settling basin (not shown), for a distance where the fire of a burning fountain cannot threaten. Inside the bottom of the tower, iB the working floor, is the balance bar 13, for which the drilling rig 24 is arranged; in the tail part of the balance bar, the walls of the working floor | Zha, to it on the axis J8 is suspended a connecting rod 20, receiving movement from the crank 33, using a belt, chain or cable from the engine room at the tower. Balancer design. 13, as applied to this case, is visible in FIG. 2 and 4. A chain or bar of a drilling tool, using an appropriate pear, is clamped in the metal sockets of the inner cheeks of the balance bars, pulled together by a yoke 14 with a cable attached to it. 15 across the unit (not shown), sent from there to the machine hut. The tail part of the balance bar 13, behind its swing axis / 7, expands with a spring 16 W and an axis 18 of the hanger suspension, being pulled at the end by a chain 79 that is also lowered or pulled from the machine hut. The engine 6aipaK is located at a safe distance from, in the event of a FontaZa fire. In cases where the machine 24 could prevent the gardener 27 from lowering, the latter is supplied with an appropriate accessory, closed from above: m 22 (Fig. 2), of proper dimensions, when lowering turning on the machine inside, as in this case, 27 is provided with an appropriate shield 27 constituting the continuation of its wall above the accessory chute 22 to close the formed hole BI of the prismatic part of the tower 5, or the same

This penetrates inside the sleeve 27, isolating the machine 24 outward from the interior. Tipari (e bye-ning) to block 6 is arranged to remove the towers, preferably screw-shaped.

At the first signs of the fountain, from the machine hut, the action on the rope 75 is pulled off the yoke / 4 from the rocker, followed by weakening the chain 79; due to the stitching of the shackle, the load of the drilling tool chain falls at the base of the shaft pipe 3, and the balancer bar, under the action of spring expansion 76, will begin to slide sideways, which is not disturbed by the shape of the axes / 7 and 75: with the connecting rod 20 falls to the floor; then, due to the reverse tension of the chain 79 from the hut, the spring 76 finally radiates the balance bar arm, as shown by the dotted line in FIG. 4. In this position, they do not interfere with the movement of box 27 and its appendage 22, which descend from the same machine hut from the hoists, garden up to the groove 23 of the upper part of the well 7. Thanks to this, the fountain's stream will be enclosed in a tower, where accumulate ejected oil, quickly fill well 7 and rise above the mouth of the casing. The gases, entrained by the fountain stream, accumulate at the top and, having reached the extreme low pressure, open the valve 8 and escape to the atmosphere, if there is no need to dispose of them. In the case when the jet takes out solids, its first pressure blows off shelf 7, and, in extreme cases, the roof of the valve is 8. The tower, filled with oil, acts, however, soothingly on the fountain; when the oil inside it reaches a known level, the plug, plugging the mouth of the ebb-hole pipe 4, pops up under pressure or; removed by hand, and oil begins to flow into settling basins; if the inflow from the wells is so rapid that the level in risers rises, then the speed of this rise is regulated by opening the hatches -72 of the drain pipe 9 until the oil flows through the top of the tower into the discharge pipe,

which, however, rarely happens. If, in this case, the gases were ignited, then, due to the absence of air inside the tower and behind the blocking of his way there, the fire would have stopped very soon by itself.

In the proposed modification, according to FIG. 5, 6 and 7, the lower part of the tower, the working floor, in addition) is a superstructure accommodating the machine, a machine with a balance bar, but without a steam boiler, which can stand nearby, in another room - a stoker, and the steam boiler in The moment is isolated from the external atmosphere, approximately, by dropping a roof cover from the roofing iron, which reduces the salinity to the boiler of the atmosphere. The grate is made so that it carries all the fuel along with it, i.e. the fire, into a deep ashpot, filled constantly to the limit with water, where the fire goes out, and the boiler will slowly cool down. The additional superstructure above the machine is firmly and tightly connected to the working floor of the tower, presented as one unit; according to the technical conditions, the engine room is fenced off from the working floor by a bulkhead with openings for belt and other gears, for the balancer, etc. In case of fire, the window O with external valves 3 can be lowered both from the place and from the distance. The iron tower is provided with holes 72 through which it is possible, in the case of a fountain of extraordinary power, to cut large stones. With such a device, a coupling 27 with blocks and ropes and a forked balancer with blocks & no are needed.
