Description

The utility model relates to the field of pipeline transport, in particular to the transportation of oil or oil products, or water in permafrost areas over long distances.

A known pipeline system for transporting liquids, in particular petroleum products in countries with a cold climate, comprising a pipeline installed inside a closed linear structure having a base plate at ground level, also two supporting elements and a roof resting on them. At the same time, funds are provided to maintain a certain temperature of the transported liquid (see French application 2522779 A1, IPC 7 F17D 1/08, 09/09/1983).

This pipeline system requires the construction of an enclosed linear structure, its heating, which significantly increases the cost of transporting liquids, makes it impossible for large distances, has a harmful environmental impact, and it is not possible to dismantle the system and transfer it to another area of use.

Also known is a piping system for pumping oil in the permafrost region, adopted as a prototype, containing an oil pipeline located inside a pipeline for pumping natural gas, which insulates the pipeline with warm oil, preventing the permafrost from melting (US patent 3735769, IPC 7 F17D 1 / 14. May 29, 1973). Moreover, the pipeline system contains pumping stations, temperature sensors and a control device that determines the gas flow rate, ensuring the temperature of the outer surface of the pipeline system not higher than 0 ° C.

This pipeline system has virtually no harmful environmental impact on the permafrost layer, but has a complex pipeline design, requires a large amount of natural gas, which is not always possible. Moreover, it does not allow for the dismantling of the system and its transfer to another area of use.

Closest to the claimed utility model is a pipeline system for transporting oil, oil products, or water, described in the patent of the Russian Federation No. 29117 U1, IPC 7 F17D 1/14, 04/27/2003).

The pipeline system for transporting oil, or oil products, or water contains a starting point with a first pumping station connected via an initial piping and piping with retaining pump units to at least one flow tank for oil or oil products and to a water source, the first pumping station equipped with two or three pumping units, one of which is reserve, while the first pumping station is connected via a collapsible pipeline with intermediate pumps stations with strapping to the final point where the sampler is installed, and at least one tank for collecting oil or oil products with a volume corresponding to at least a half-day supply, a settling tank for collecting a mixture of oil or oil products with water with a volume of at least 100 m ³ and a reservoir or container for receiving the fresh water, the collapsible tubing is made of a steel pipe with an inner diameter of 100 to 250 mm, interconnected connection type "bell" and assigned to earth and / or on logs made of logs, as well as laid underground or above ground when overcoming artificial or natural obstacles, moreover, in the collapsible pipeline at the pipeline crossings through streams, streams, swamps, lake contours, intersections of roads and driveways, valves for emergency blocking are installed, and on the ascending sections of the route

collapsible piping and in the piping of pumping stations installed check valves and trap inserts for receiving separators, and at intervals of 15-20 km, due to the degree of wear of the material of the devices, intermediate nodes for receiving and starting separators are installed. The system can be additionally equipped with pump-heating and / or thermal stations, and the volume of the supply tank for oil or oil products at the starting point is at least 2 hours guaranteed supply.

The objective of the utility model is to reduce the cost of creating a pipeline system that provides reliable, leak-free transportation of oil, or oil products, or water over long distances (several hundred kilometers) in natural climatic conditions, such as permafrost, as well as ensuring its economical assembly without using welding in the field, and transportation, with the possibility of dismantling the system and transferring it to another area of use.

This technical result is achieved due to the fact that the pipeline system for transporting oil or oil products or water contains a starting point with a first pumping station connected via an initial piping and pipelines with backup pumping units to the source of pumped oil or oil products or to a water source. The first pumping station is connected via a collapsible pipeline with intermediate pumping stations with strapping to the end point, in the strapping of which a sampler is installed, and at least one tank for collecting oil or oil products with a volume corresponding to at least a half-day supply is placed, while a collapsible pipeline is assembled from elements of a collapsible pipeline, which are made of low-alloy steel pipes with a length of a multiple of 0.15 m and with a nominal diameter of 100 mm, or 15 0 mm, or 200 mm, closed

to each other by means of a “bell” -type connection and installed on the ground and / or on log linings, and in case of overcoming artificial or natural obstacles laid underground in protective cases, moreover in a collapsible pipeline at pipeline crossings through streams, streams, swamps , lakes, crossings of roads and driveways, valves for emergency shutdown are installed, and check valves and trap inserts are installed on the ascending sections of the collapsible pipeline and in the pipings of pumping stations and for receiving separators. The system can be additionally equipped with pump-heating and / or thermal stations, while the volume of the supply tank for oil or petroleum products at the starting point is at least 2 hours guaranteed supply.

The figure shows a diagram of a pipeline system for transporting oil or petroleum products or water.

The pipeline system for transporting oil, oil products, water contains a starting point with a first pumping station connected via an initial piping 1 and pipelines 2 with retaining pump units 3 to at least one flow tank 4 for oil or oil products and to a water source 5, which can be used by any body of water or a river with clean water.

The first pumping station is equipped with two or three pumping units 6, 7, 8, one of which, for example, is 8-standby, while the first pumping station is connected via a collapsible pipeline 9 with intermediate pumping stations 10 with strapping (not shown in Fig. ) to the final point, in the piping of which a sampler 11 is installed, and at least one tank 12 for collecting oil or oil products with a volume corresponding to at least a half-day supply, a settling tank 13 for collecting a mixture of oil, or oil ucts with water of not less than 100 m ³ and a container or reservoir 14 for receiving pure water, wherein the collapsible conduit

9 is made of low-alloy steel pipes with a length of 0.15 m and with a nominal diameter of 100 mm, 150 mm or 200 mm, closed together by a bell-type connection and installed on the ground and / or on the liners (not shown in Fig.) from logs about 2 meters long and about 20 cm in diameter, and also laid underground while overcoming artificial or natural obstacles, moreover, in the collapsible pipeline 9, valves for emergency shutoff are installed after about 5 km (not shown), and on ascending sections of the national team track On the collapsible pipeline 9 and in the piping of the pumping stations, check valves and trap inserts for receiving separators (not shown in Fig.) are installed, and in the middle of the route an intermediate receiving / starting unit for separators is installed (not shown in Fig.). The system can be additionally equipped with pumping and / or thermal stations (not shown in FIG.). The volume of the supply tank 4 for oil or petroleum products of the starting point is at least 2 hours guaranteed supply.

Preliminarily, thermal and hydraulic calculations are carried out for the pipeline system, allowing to determine the required number and location of pumping stations and heat pump stations on the pipeline route 9. providing optimal conditions for its operation. On the "hot" collapsible pipeline 9 it is possible to install three types of stations: thermal, pumping and pumping and heating, while any combination of them is practically possible.

Pump installations of the starting point of the pipeline system are used to ensure the supply of water to the pipeline 9 for filling, pumping and hydraulic testing; the supply of 9 oil or oil products to the pipeline; displacement of oil or oil products by water and water by oil or oil products by direct contact or using separators. At the outlet of the pumping station, the technological piping of the paraffin sediment removal unit should be mounted.

Separators are intended for the separation of two grades of oil during their sequential pumping, as well as for the separation of oil and water or oil and air when emptying the pipeline 9 from oil. For these operations, a polyurethane foam separator is provided, and for cleaning the pipeline 9 from contamination after installation, an elastic cuff separator is used, consisting of two sealing cuffs molded from gas-oil-resistant rubber together with the core connecting them. The separators are provided with a radioactive isotope, and their movement through the pipe 9 is controlled by a radiometer.

Installation of the collapsible pipeline 9 is carried out from low-alloy steel electric-welded straight-line pipes, a cone is welded to the ends of the pipes, and a bell, or two bell, or two cones are welded on the other side. In addition, elements are used in the form of squares, the length of which is also a multiple of 0.15 mm, having a different angle, and at the ends there is a cone on one side and a bell on the other. In the socket there are large and small annular grooves. A rubber o-ring is installed in the large annular groove, and a microporous rubber lining and a steel locking ring in the small groove. The microporous lining is installed under the locking ring to create a coaxial position of the locking ring with respect to the socket and protects the cavity of the small annular groove from dirt and other items.

The execution of the pipeline from low-alloyed steel pipes with a length of 0.15 m makes it possible to exclude additional corrosion protection and to ensure any length and installation scheme, having previously determined the required number of pipe sizes of the desired length in accordance with the terrain. At the same time, there is no need to cut and weld pipes in the field, and to assemble from pipes manufactured and tested (controlled) in the factory.

This provides the possibility of axial mobility of the constituent elements of the pipeline.

When the internal diameter of the collapsible pipeline 9 is less than 100 mm, the hydraulic resistance significantly increases, which requires the installation of additional intermediate pumping stations 10 and worsens the economic performance of the system, and the use of the pipeline 9 with an internal diameter of more than 200 mm does not allow its installation and dismantling with a type connection “Bell”, since the weight of pipes, the length of which, as a rule, is 6 m, does not allow carrying out these works in permafrost conditions.

The lining for pipes made of logs with a diameter of about 20 cm is explained by the fact that the pipeline system is intended for use in permafrost areas, that is, in the forest-tundra zone, where the diameter of trees rarely exceeds 18-20 cm, so the use of logs of the specified diameter is economically justified, since trees of pipeline route 9 can be used for this. At the same time, this height of the linings provides a quick and significant snow cover of pipeline 9. which ensures the preservation of its thermal balance, and 2 Three times the length of the logs practically does not allow the pipes to sink into the ground in the summer.

Laying of the pipeline 9 on slopes with a transverse slope of 8-11 is carried out by cutting and adding soil in order to create a working strip (shelf), with a transverse slope of the slope of 12-18 ° necessary to set up ledges to prevent slipping of the soil, with a slope above 18 ° the shelves should be provided only due to soil cutting.

In mountainous areas, when laying two or more parallel threads of pipeline 9, separate shelves or laying of threads on one shelf are provided, but the distance between the threads is maintained at least three meters.

Underground laying of pipeline 9 is allowed in exceptional cases, when bypassing settlements, industrial and agricultural enterprises, airfields, railway stations, sea and river ports and marinas, in fire hazardous areas.

At the crossings of the pipeline 9 through watercourses, streams, swamps, on the bypasses of lakes, at the intersections of roads and paths, valves for emergency blocking are installed, and at the intersections with the migration routes of animals and driving reindeer, arched crossings are installed.

For tight separation of sections of the pipeline, wedge gate valves are used.

The non-return valves are used to prevent the pumped liquid from moving in the opposite direction when pumping and unloading pipelines from excess hydrostatic pressure on the ascending sections of the route, as well as in the piping of the pumping stations for automatically disconnecting the pressure and suction lines when starting up the pumping stations and automatically letting the pumped liquid pass the station at her sudden stop. The design of the check valves provides the opening of the full cross section of the pipeline 9 and the passage of the dividers.

At the end point of pipeline 9, a piping is equipped with a sampler that allows you to take separators, take samples from the stream, separate and send clean oil or oil products to tank 12, a mixture of oil and water to tank 13, and also send them to a tank or reservoir 14 - clean water.

Inserts - traps for receiving separators, as well as an intermediate unit for receiving and starting separators are intended for receiving and starting separators during sequential pumping of products and emptying of the pipeline 9.

After the assembly of the pipeline system, it is tested, tested for strength and tightness.

The supply of oil or oil products or water to the pumping units 6, 7. 8 of the first pumping station from the tank 4 or the water source 5 is provided by booster pumping units 3 with electric drive through pipelines 2, and then through the intermediate pumping stations 10, the pumped liquid through pipeline 9 arrives at the final point where, depending on the nature of the pumped liquid, reservoirs 12 or 13 or a container or reservoir 14 are used.

The indicated volumes of the capacities of the initial and final points of the pipeline system make it possible to ensure its reliable operation without interruptions in supply.

If necessary, for example, when the oil well is depleted, the pipeline system together with the pipeline 9 can be dismantled and moved to another active well.
