Description

The utility model relates to the oil and gas industry and can be used in the preparation of sites for the construction and arrangement of industrial and civil facilities, mainly associated with hydrocarbon raw materials.

When arranging deposits in permafrost areas, special importance was attached and is attached to the issues of engineering protection of building sites from these erosions and to the prevention of surface water from entering underground groundwater and its protection from pollution.

However, during the exploitation of hydrocarbon deposits, in particular oil and / or gas fields, in the Far North, the problem of erosion of artificial and natural fields of hydrocarbon fields and other industrial and civil facilities by storm and melt running waters was revealed.

These decisions turned out to be insufficient during the further operation of the sites since annual additional costs for the restoration of blurry sites were required. The construction of fishing facilities on weakly frozen soils required the development of additional measures to create normal natural moisture in the upper soil cover, which would ensure minimal seasonal thawing and, as a result, prevent erosion of the upper layer of the subgrade.

The technical result of the proposed utility model is to increase the reliability of the hydrocarbon production site in the Far North by reducing erosion and thawing of the subgrade.

The necessary technical result is achieved in that the hydrocarbon field in the Far North includes hydrocarbon production areas with their livelihoods, having a drainage system along their territory and / or along their perimeter in the form of drainage trays from longitudinally cut

along the entire length of pipes with a diameter of 820 1420 mm, laid on a pillow of a mixture of crushed stone with sand and intended for storm or melt water flows in gravity flow mode, which are in communication with a drainage channel along the perimeter of the mentioned sections, having branches to the landscape and made with slopes equipped with cellular panels laid on a prepared base - soil with a layer of film or non-woven synthetic material on it and filled with a heat-insulating layer of moss and / or peat-sand mixture with grass cover, while the cellular panels are equipped with all and natural to artificial slopes across all sites, and the ground posts with the drainage troughs drainage channel filled honeycomb panel hardiness sorted gravel fraction 60 100 mm mixed with sand.

In addition, gas and / or oil production sites and life support facilities, which include at least a water supply system, an energy supply system with a substation, material depots, a fire station, a shift camp, are accepted as hydrocarbon production sites;

The slopes of the platforms are equipped with Geoveb mesh panels, the drainage trays for parts of their length or along their entire length are made with through holes with a diameter of 10 25 mm.

Figure 1 shows a fragment of a General view of the site of hydrocarbon production.

Figure 2 shows a cross section of the drainage channel.

Figure 3 shows the message of the drainage tray with drainage feces.

The hydrocarbon production site includes (Fig. 1) a hydrocarbon production site 1 with their livelihoods (shown conditionally as a single site). This section has a drainage system, conventionally shown along the perimeter of the site, in the form of drainage trays 2 of longitudinally cut along the entire length of the pipes for storm or melt water flows. These trays are in communication with the drainage channel 3 with slopes 4, equipped with mesh panels. Figure 1, in addition, shows the highway 5.

The cellular panels (figure 2) are laid on a prepared base - soil 6 with a lining of a film or non-woven synthetic material 7 on it and filled with a heat-insulating layer of moss and / or peat-sand mixture with grass cover 8. In figure 2, in addition, the embankment of side 9 of the drainage channel is shown, as well as the soil of the general planning embankment 10. All natural and artificial slopes in all sections are equipped with mesh panels.

In the places where the drainage trays with the drainage channel (Fig. 3) communicate, the honeycomb panels are filled with sorted frost-resistant crushed stone 11. The drainage trays are laid on the pillow 12. The drainage trays 2 themselves can be made with through holes 13 (conventionally shown along the entire length of the trays).

The solution according to the proposed utility model was developed on the basis of existing experience in operating sites for integrated gas treatment at the Zapolyarnoye gas and oil condensate field. The solution provides protection against soil erosion of artificial or bulk and natural ground cover from the effects of wastewater.

The use of cellular panels, for example, such as "Geoveb" and a drainage system with drainage trays, a drainage channel and outlets of water flows to the relief, is provided.

Natural and artificial slopes of all sections of the hydrocarbon field are reinforced with cellular panels, for example, Geoveb panels with their obligatory filling with a heat-insulating layer of moss or peat-sand mixture with an active porous structure, fixed from erosion by grass cover and not allowing heat flow from the base of the site . In the places where the drainage trays with the drainage channel communicate, the mesh panels are filled with sorted frost-resistant crushed stone from fraction 60 rock 100 mm mixed with sand. This solution provides a cooling effect at the base of the site due to its ventilation. The temperature here is 2-4 ° C lower than the outside air. This allows you to maintain a negative temperature at the base of the site throughout the year, keeping the soil from thawing.

An additional preservation of the negative temperature regime can be a solution combining the filling of the cellular panels in the lower part with sorted frost-resistant crushed stone from fraction 60 rock 100 mm in a mixture with sand, and in the upper part a heat-insulating layer of moss or peat-sand mixture with an active porous structure, fixed from erosion by grass cover.

Trays of general storm sewage were laid on the site to divert water beyond it to protect from erosion of "bumps" by water flows in areas, overpasses of methanol facilities and the resulting erosion. The drainage trays are laid, passing into the drainage channel with slopes equipped with mesh panels.

Drainage trays are laid in places where the operation of cellular panels is difficult. Drainage trays can be concreted from below using cement-sand mortar. Along the entire perimeter, these pipes from above, on a concreted base, are covered with crushed stone mixed with sand. Through trays are cut through holes. To prevent erosion of the soil at the ends of the pipes and the exit of water, reinforced concrete heads were made.

In some places along the trays on both sides paving prefabricated reinforced concrete tiles were laid along a layer of crushed stone in a cement-sand mortar.

Drainage channels are used to collect and drain water outside the boundaries of the sites (material storage warehouse, fire station, substations). The slopes of the channels are protected by Geoveb cellular panels to the entire height along the film layer and are filled with a peat-sand mixture with grass cover.

This arrangement of the site allows several times to reduce annual costs for the permanent restoration of the upper layer of the subgrade, to protect multi-permafrost soils from thawing, to prevent soil erosion.
