The method of construction of the dumps

 

(57) Abstract:

The invention relates to methods for the production of works in hydraulic engineering, to methods of construction of places for disposal of oil and gas in well drilling and operation of wells. The method of construction waste, including the designation of the boundaries and configuration of land drainage, filling or mineral alluvium soil, waterproofing technological platforms, external obalovanie on the periphery of the technological platform, the disposal of waste production and consumption are carried out at the sites between the outer and inner obalovanie, which is constructed around the provisions of liquidated wells. The method allows efficient use of land resources, reduce harmful effects on the environment. 1 Il.

The method of construction of the dumps relates to methods for the production of works in hydraulic engineering, in particular to a method of construction of landfills for disposal of production and consumption of oil and gas recovery.

A known method of construction of the polygon, which consists in the territory, where the base are clay and hard splink the 1999, S. 430).

However, this method has significant drawbacks.

For the construction of the landfill would need to find a new land that is associated with certain costs of finding an appropriate place for future land use and construction, landfill disposal of production and consumption. In addition, alienated land that could be used for agricultural purposes. This way of constructing polygons unacceptable for wetlands in Western Siberia, where the underlying upper horizons of clay and heavy loamy soils are absent.

Closest to the proposed method is created upstream of artificial reason (see UDC 622,692.23.072 Kolomeitsev such as the Construction of foundations for well drilling in Western Siberia. Survey information. Ser. "Oilfield construction. - M.: VNIIEM, 1981, S. 17-18) with the subsequent construction of polygons in accordance with SNiP 2.01.28-29 "polygons for the neutralization and disposal of toxic industrial waste."

However, this method has a significant disadvantage in the fact that for its implementation it is necessary to make the polygon. In other words, the implementation of this method requires a relatively large cost.

The aim of the invention is the efficient use of land resources, reducing the cost of construction of disposal sites harmful effects on the environment.

This objective is achieved in that the disposal of waste production and consumption are carried out at the sites between the outer and inner obalovanie, which is constructed around the provisions of liquidated wells.

The drawing shows the circuit implementation of technical solutions.

The scheme consists of entrance 1 on sectional pad 2 with external obalovanie 3, the provisions of liquidated wells 4, around which were built the internal obalovanie 5.

The method is implemented as follows.

For landfills for waste pick sectional area 2, which are provisions liquidated wells 4. Build internal obalovanie 5 of the mineral soil. Depending on the distance between the provisions of liquidated wells 4 internal obalovanie 5 do around each position eliminated wells 4 or one the first pad 2 through the entrance 1 and placed on a well pad 2 between the inner 5 and outer obalovanie 3. Pad pad 2 if necessary, divided into parts, each of which fill waste separately.

The beneficial effects of the present technical solution is in the rational use of suitable land for the purpose and previously allotted land to the company, reducing the cost of construction of landfills waste, harmful effects on the environment.

The method of construction waste, including the designation of the boundaries and configuration of land drainage, filling or mineral alluvium soil, waterproofing technological platforms, external obalovanie on the periphery of the platform, characterized in that the disposal of waste production and consumption are carried out at the sites between the outer and inner obalovanie, which is constructed around the provisions of liquidated Skagen.

FIELD: oil industry, particularly oil-field construction, namely to built storage pit adapted for oil-drilling waste storage.

SUBSTANCE: method involves digging out ground; erecting banking; forming waterproofing screen of film material with weld seams; connecting polymeric adhesive strips to back film side transversely to weld seams facing outwards so that space between strips is not more than 3 m and strip ends extend over outer screen surface, wherein the waterproofing screen has ample size; securing one end of waterproofing screen on pit edge by shackles and covering thereof with ground along the full pit edge; gradually laying unstrained waterproofing screen on pit bottom and side walls to reach opposite pit edge so that weld seams face outwards; loading screen edges across the full width and forming pleat at pit edge along the full perimeter thereof; securing the pleat with ground; fastening free edges of laid waterproofing screen along the full pit perimeter with shackles and covering thereof with ground; folding free screen edges in two in shackle installation areas and placing cantledge on pit bottom along the full perimeter thereof; placing textile protective screens over rocky ground zones. The waterproofing screen dimensions may be determined from given relation.

EFFECT: increased liquid product storage reliability.
