Oil storage device capable of achieving freezing through freezing pipes and construction method thereof

Abstract

The invention discloses a construction method of an oil storage device capable of achieving freezing through freezing pipes. The construction method comprises the specific steps that an appropriate geographic position is selected, a main body structure is constructed through reinforcing steel bars, and a fiber concrete space enclosing structure is formed from high-pressure jet grouting fiber cement; a working well is dug; freezing pipes are inserted to the periphery of the fiber concrete space enclosing structure; a refrigerant is introduced into the freezing pipes for freezing soil, and frozen oil with the high strength and good sealing performance is formed; deep-stratum soil is dug away, and an oil storage space is formed; the inner side of the fiber concrete space enclosing structure is paved with waterproof roll, and the upper soil body layer of the oil storage space reinforced through high pressure spouting; and hydraulic oil is injected through high pressure, and sealing is carried out. The invention further discloses the oil storage device capable of achieving freezing through the freezing pipes. The problems of excessive spending and explosion caused by storage in deep-layer soil in the prior art are solve, implementation is convenient, adaptability is good, safety and reliability are high, and no pollution is produced.

Description

technical field [0001] The invention relates to an oil storage device and a construction method thereof, in particular to a freezing tube oil storage device and a construction method thereof. Background technique [0002] With the rapid development of my country's economy, the demand for oil and gas is also growing rapidly. Domestic oil and gas resources are far from meeting the needs of consumers. In order to meet the needs of oil supply, respond to emergencies, stabilize oil prices, and ensure the security of the national economy, my country is stepping up the construction of a national oil strategic reserve system. Oil reserves can be divided into land storage tanks, offshore storage tanks, underground storage tanks, underground water-sealed caverns, etc. in terms of storage facilities. Most traditional storage devices are inconvenient for canning. It is labor-intensive and prone to deposition and solidification during storage, which is not very convenient for this sto...

Problems solved by technology

Although there have been some successful cases of similar projects in foreign countries, due to various reasons, there is no effective way to learn the core technologies of some cavern construction, resulting in the construction of related projects in our country is still in the exploratory stage

[0006] Nowadays, the use of underground caverns to store oil is a new type of oil storage technology. Generally, stone caves are dug in places with stable groundwater. Steel oil tanks are placed in the caves and a layer of glass fiber reinforced plastic is required on the outside for protection. , but this kind of material cannot be placed in deep places, and the cost is expensive, so the above problems need to be solved urgently
