Abstract
The utility model relates to an underground gas storage grotto in an anticline geologic structure and aims at providing the underground gas storage grotto in the anticline geologic structure, wherein the underground gas storage grotto in the anticline geologic structure is small in engineering investment and construction difficulties and remarkable in economical benefits, so that the underground gas storage grotto is not limited by the geologic condition of salt rocks, facilitates popularization and promotes development of compressed air energy accumulation. The technical scheme includes that the underground gas storage grotto in the anticline geologic structure is characterized in that the underground gas storage grotto is placed in rocks with the anticline geologic structure, high porosity and high permeability, the grotto is placed on the core portion of the anticline and the upper portion of the rocks of the anticline geologic structure and the lower portion of the rocks of the anticline geologic structure are saturated with injected water. The underground gas storage grotto in the anticline geologic structure is applicable to the field of the compressed air energy accumulation.
Description
Technical field
The utility model relates to a kind of compressed-air actuated gas storage cavern, the underground gas storage cavern in especially a kind of Anticline Geologic.Be applicable to the compressed-air energy storage field.
Background technology
Compressed-air energy storage is a kind of new electric energy storing technology, is the electric energy storing system that can realize large capacity and long-time power storage.It when needed, discharges pressure-air by decompressor acting generating by the unnecessary electric energy of compressed-air-storing.Compressed-air actuated gas storage cavern, although structure is fairly simple, very crucial.The common addressing in this gas storage cavern also can utilize existing or discarded mine, tunnel etc. underground, yet must guarantee the high pressure sealing of gas storage cavern.In order to guarantee the tightness of structure, can adopt the rubber back boxing, also can adopt the mode of water seal, reduce cost.
Since the underground gas storage cavern have volume large, bear the high characteristics of pressure, the gas storage cavern in the compressed-air energy storage power station of abroad having moved at present is positioned at the rock salt area mostly, utilize water filling that salt is dissolved and to form the cavity, has preferably tightness, and low cost, but must have this geological conditions.If there is not this suitable geological conditions, need artificial reconstructed or the construction gasholder, cost will increase greatly.The relevant expert in Hubei, the ground such as Qinghai, the Inner Mongol, Gansu carried out geological survey, did not temporarily find suitable geological conditions, became one of key issue of restriction China development compressed-air energy storage.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, the underground gas storage cavern that a kind of construction investment is few, difficulty of construction is little, the Anticline Geologic of remarkable in economical benefits is interior is provided, so that the underground gas storage cavern is not subjected to the restriction of rock salt geological conditions, be convenient to promote, promote the development of compressed-air energy storage.
The technical scheme that the utility model adopts is: the underground gas storage cavern in a kind of Anticline Geologic, it is characterized in that: described underground gas storage cavern be arranged on have Anticline Geologic, in the rock of high porosity and high osmosis, the cavern is located at the nuclear section of anticline, and water filling is saturated in the overlying rock of Anticline Geologic and rock stratum, bottom.
Described overlying rock and rock stratum, bottom are through grouting treatment.
Described overlying rock and rock stratum, bottom are equipped with geomembrane.
Apply curtain grouting around the described cavern.
Be provided with the turnover gas well between described Mass Near The Top of Underground Cavity and the ground.
The beneficial effects of the utility model are: 1, the utility model utilizes this Geologic Structure Feature storing compressed air of anticline, has overcome and has utilized merely rock salt as the restriction of gas storage; 2, by guaranteeing to improve the tightness of gas storage cavern to overlying rock and the water filling of rock stratum, bottom; 3, the total form takes full advantage of the physical characteristic of Geologic Structure Feature and rock stratum, utilizes degree high, cost saving, and be conducive to popularize, can provide new mentality of designing for construction and the popularization in compressed-air energy storage power station.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Under the powerful squeezing action of crustal movement, plastic strain can occur in the rock stratum, produces a series of wavy bending, is called fold.The base unit of fold is fold, and fold has two kinds of grown forms, and a kind of is to tiltedly, and a kind of is anticline.Generally be the bending that projects upwards on the anticline profile wherein, the rock stratum is outward-dipping from the center, and nuclear section is old rock stratum, and both wings are new rock stratum.The trend of anticline rock stratum is natural arch, and Stability Analysis of Structures is stressed even, and is difficult for storing underground water, constructability.
As shown in Figure 1, present embodiment is a kind of underground gas storage cavern that utilizes this special geological structure of anticline and saturated rock to come storing compressed air, cavern 1 is located at the nuclear section of anticline, and water filling is saturated in the overlying rock 2 of Anticline Geologic and rock stratum, bottom 3, to stop the leakage of air, guarantee the tightness of cavern, and play the effect of regulating cavern's volume and pressure.Between 1 top, cavern and ground, be provided with two turnover gas wells 4 in this example, can by this pass in and out gas well with air compressing to the cavern in 1 or in the cavern, discharge.
The specific implementation method of present embodiment is as follows:
1, at first carry out geological exploration, the trend of clear and definite geological structure, particularly arch structure and length, and the rock stratum attribute in the anticline are preferably high porosity, high osmosis rock;
2, according to compressed-air actuated volume and definite volume and the buried depth that stores the cavern of pressure;
3, excavation underground gas storage cavern 1 in anticlinal nucleus;
4, overlying rock 2 and 3 water fillings of rock stratum, bottom of arch structure are saturated, improve the tightness of whole gas storage cavern, prevent air leakage.
In order to guarantee the water content in the rock stratum, can be by in overlying rock 2 and rock stratum, bottom 3, being in the milk, installing geomembrane, applying the mode such as curtain grouting around in the cavern and prevent that the current in the rock stratum from losing.
