Description

The present invention relates to systems for suppressing oil fires during drilling or fires of other liquid substances. When using this invention, the release of burning material is stopped, so that the oil drill pipe (s) is blocked with the possibility of re-opening these pipes.

Three different methods of extinguishing an oil fire are known.

Water is injected into the fire; at the same time, the fireman, covered by a protective device, approaches the fire and tries to manually close the valve of the oil pipe. This method is dangerous and requires a lot of water, which is not always available at the fire site.

By exploding a well with burning oil, the oxygen consumption in the surrounding area increases so much that the fire suffocates from a lack of oxygen. After that, valves and other broken equipment can be replaced. This method is very dangerous.

By drilling a new wellbore in the same oil well with a burning oil pipe and pumping water into it, the oil discharge is replaced by the water discharge, and the fire goes out. This operation is costly and time consuming, and its success cannot be guaranteed. In addition, its implementation is dangerous.

The main parts of the proposed installation are: a hydraulic cylinder, a piston, a drilling cylinder, a clogging cylinder, a drill, a box clamp, a hydraulic motor or other engine, a blocking valve, a hydraulic reservoir with pipelines and a pressure accumulator, and an automatic control and monitoring system. The essence of the invention lies in the fact that each oil and / or gas drill pipe, in accordance with its size, encloses its own drilling installation. A drilling installation is understood to mean a drilling and plugging mechanism necessary to close one gas or oil drill pipe.

Several drilling rigs can use a common energy source with its hydraulic reservoir. In conditions of underwater drilling, for example, on oil drilling platforms on the high seas, pressurized water can be sent to its own mechanism for use in the system. To create pressure, an explosion can also be made inside the massive cylinder with pistons at both ends, and this pressure is directed through a separate central reservoir or directly into the hydraulic reservoir. Pressure can also be diverted from an oil or gas drill pipe under the drilling unit through a drilled shaft and a joint fixed to it. The required number of drilling units can be installed, for example three.

The proposed system is designed to contain an oil and / or gas fire and, thus, prevent the destruction of large oil and / or gas drilling equipment. This installation can be mounted on under construction, already built and even on burning oil and / or gas drilling systems. Since this equipment is installed remotely and has automatic control, an oil fire does not pose a threat to people when the equipment is pre-installed on an oil drilling system and its installation on a burning system does not entail the need to be in close proximity to the fire ; on the contrary, it is installed underground. Thus, the advantage of this invention is that this equipment and method is safe and allows you to save the environment and money, as well as oil or gas.

The invention is described in detail below with reference to the accompanying drawings, in which FIG. 1 is a cross-sectional view of an apparatus in a state in which a first drill cylinder is in motion;

FIG. 2 is a cross-sectional view of the apparatus in a state in which the first clogging cylinder is in place;

FIG. 3 is a cross-sectional view of the apparatus in a state in which all three clogging cylinders are in place;

FIG. 4 is a cross-sectional view of a hemispherical cylinder;

FIG. 5 shows a local section in the transverse plane of a conical cylinder with a grinding surface;

FIG. 6 shows a local section in the transverse plane of a conical cylinder with a protruding blade;

FIG. 7 shows a mounted installation and a local section in the transverse plane of a hydraulic reservoir; the drawing does not show the structure of the underground cavity in which the installation is located;

FIG. 8 shows in detail a box clip and a locked blocking valve;

FIG. 9 illustrates an embodiment in which a drill cylinder and a plug cylinder (which, however, are not shown in the drawing) operate from one side of an oil and / or gas drill pipe, and use an oil seal to guide said cylinders and seal the cut weld. In the drawing, the oil seal on the right side is not tightened.

As can be seen from FIG. 1, 2 and 3, the essence of the invention lies in the fact that on the right side of the oil and / or gas drill pipe and the plugging cylinder there is the same pushing and / or rotating mechanism as on the left side of these oil and / or gas drill pipes. In addition, as follows from the drawings, it is advisable that the drilling rigs, acting one after the other, were placed on opposite sides of the oil and / or gas drill pipes, so that sequentially performed drilling, as well as blocking, began on the opposite sides of these pipes. If three or more drilling rigs are placed around these oil and / or gas drill pipes, they can be placed so that each starts from its own direction, different from the others, thereby minimizing the resulting force acting on the pipes when drilling and plugging .

When the installation starts to work, the pressure from the pressure accumulator 10 is discharged into the hydraulic reservoir 11, under the pressure of which the hydraulic motor 8 and the valve begin to act. Oil flows into the hydraulic cylinder 1, which pushes the piston 2, and this piston pushes the drill 5 and the drill cylinder 3 forward. After the cylinder 3 passes through the oil drill pipes 7 to a sufficiently large distance, the mechanical check valve gives the command to return the drill 5 and cylinder 3, and then instructs the clogging cylinder 4 to clog. The cylinder 4 may also be located behind the cylinder 3, in which case movement in only one direction is necessary. If necessary, after the operation of all drilling rigs, a blocking valve may be closed. This action is carried out hydraulically or using explosives. Clogging cylinders only push or, in addition, still rotate by rotating engines, for example, for grinding. During or after plugging, an extinguishing agent, such as liquid nitrogen, may be additionally introduced into the gas or oil drill pipe under pressure. It is introduced through an opening cut in an oil or gas drill pipe by a device such as cylinder 3. All this can be done without using electricity by means of power control, in which the initiated action can no longer be stopped. The equipment is fixed around the oil pipes using a box clamp 6 and is supported at the base. Due to the fact that the pipes of various sizes are sealed separately, the fall of the upper pipes is prevented. An oil drilling system can be brought back into service by installing retaining rings on cut pipes and removing plugs.

For blocking an external oil or gas drill pipe, the apparatus described below generally with reference to FIG. nine.

In addition to the parts described above, the invention also includes an oil seal 14, a tightening device 15, locking locks 16, a sliding bearing 17 (for example, a strip of chromium), a seal 18 in which oil is under pressure, a locking groove 19 and a housing groove 20. That end the gland 14, which is facing the oil or gas drill pipe, has the shape of the outer wall of this pipe and is made very sharp. In addition, the gland is installed in place by tightening by means of a bearing 17 and a tightening device 15 provided with an external thread interacting with the internal thread of the installation housing 12. Tightening can be done manually during installation or by an automatic mechanism after the installation starts. Around the gland tension device 15, a locking groove 19 is formed, into which locking locks 16 are pressed, pressed against the housing 12 under the action of a spring or under liquid pressure, when the gland tension device is inserted to the required depth. In addition, a housing groove 20 is formed in the installation case 12, which, in addition to the stuffing box tensioner, is designed to prevent loosening of the stuffing box 14 when it reaches a fixed depth. The purpose of the gland 14, which is installed in place by tightening, which is very sharp at the end facing the oil or gas drill pipe 7, and which is made of very hard material, is to seal the sealed seam of the oil or gas drill pipe 7, drilled and sealed, and the direction of movement of the drilling-plugging unit 34 moving within it. The seam between the oil seal 14 and the shaft 13 is sealed by means of a seal in which the oil is under pressure. When drilling, the drilled parts of the oil or gas drill pipe 7 remain in the drilling-plugging unit 3-4.

Monitoring and control of the valve can be carried out:

1. Using well-known methods of process control and automation.

2. By electrical measurement of changes in the magnetic field of the system by means of sensors. These changes can be caused, for example, by a change in the following values: flow, current direction, temperature, pressure, flow stability. Changes in the magnetic field are recorded due to changes in several resistances that are directed by the transistor and integrated by the computer, while the valve is controlled by the limit values encoded in the computer. If the valve is installed under water, the environment surrounding the valve and changes in it can also be controlled in this way. In addition, data on any other observations, such as the threat of terrorism, can be transmitted to the control and management terminal.

3. By analyzing and establishing values, such as temperature, pressure, rotation speed and feed rate, as well as their changes using sensors mounted on the end of the drill and on the shaft.

To control the valve, you can use:

1. Independent control of the valve with power transmission: closing the valve requires only one command.

2. Direct control or control via hydraulic valve.

3. Pneumatically actuated hydraulic valve. These actions can be performed manually or automatically; and in the latter case, the system begins to act as a result of the fuse of the autonomous closing system. As measured values, you can use temperature, gas composition, pressure, flow, vibration, mechanical and electrical methods and other similar values that automatically give instructions to the valve when a person does not have the opportunity to give them.

The following sensors can be installed on the valve to indicate the operating status of the valve.

1. The pressure sensor in the hydraulic reservoir, indicating the beginning of the valve and showing the working pressure of the oil.

2. A meter that displays the amount of oil and indicates the distance of movement:

- the amount of oil entering the cylinder indicates the distance of movement;

- The pressure sensor on the back of the cylinder indicates that reverse movement is working.

3. The pressure sensor in the clogging cylinder indicates clogging.

4. A sensor indicating rotation of the drill is located on the drill shaft.

5. A sensor located on the tip of the drill can measure the prevailing values.

These values are used in automatic data processing to form a picture on the computer terminal that describes in detail the operation of the valve.
