Description
Technical field
The present invention relates to underground water seal cave depot technical field, in particular to a kind of nature of underground water seal cave depot water curtain system
Method for supplementing water.
Background technique
Underground water seal cave depot is a kind of not lining cutting rock openings, and oil storage principle is very simple, i.e., due to being full of in palisades
The static pressure of underground water is greater than the indoor oil storage static pressure in hole, and oil product is mothballed always in one be made of palisades and crevice water
It in closed cavern space, leak out oil product will not；Simultaneously as oil is different with the specific gravity of water, You Heshui will not be mixed mutually,
Oil is placed among the encirclement of water by the principle using water than oil weight, so that being only possible to is that water seeps in hole, and oil can not be toward hole
Outer leakage, therefore, oil are in underground water always and are formed by water subfill along palisades infiltration, to reach long term storage oil product
Purpose, as shown in Figure 1.
The indoor oil in hole and oil gas leak outward along rock cranny channel in order to prevent, and people usually utilize in crack rock
Underground water realize that, to the hydraulic seal of cavern, hydraulic seal can be divided into nature water seal and artificial hydraulic seal two ways.Such as
Fruit stability of groundwater level and supply is abundant, can be used nature water seal, water seal cave depot that the American-European countries of early stage builds (including LPG,
The gas storage such as air cushion type pressure balance chamber cavern), it is all made of nature water seal mode.However, with the expansion of storage cavern scale, and to safety
With the raising of environmentally friendly reliability requirement, in the state of the art, the method that uniquely can be effectively controlled leakage is exactly artificial waterpower
Sealing.When groundwater level cannot keep it is steady in a long-term when or supply it is limited when, the underground water under natural water seal will form precipitation
Funnel, cavern top is possible to the crack passage for connection earth's surface occur, so as to cause hydrocarbon seepage.So-called artificial hydraulic seal side
Water curtain system is actually arranged in formula above cavern, and the water curtain system is usually by water curtain tunnel, water injection hole and recharge well
Composition.As shown in Fig. 2, the setting of water curtain system can farthest make all structural planes in rock mass be interconnected, is formed and seeped
Flow network, and by rock cranny seepage flow into cavern, so that the minimum point of precipitation funnel is raised to water curtain, to keep Dong Shiding
To between water curtain water injection hole absolute altitude, there are certain head pressure (related with cavern's internal pressure), that is, it is high to obtain certain water level safety
Degree, thus it is ensured that the long-term effectiveness of entire cavern hydraulic seal.Currently, underground water seal cave depot engineering both domestic and external is general
Artificial hydraulic seal is carried out all over using water curtain system.
By above-mentioned water-seal principle it is found that if moisturizing to water curtain system, precipitation funnel will gradually develop not in time, finally
Inevitably degenerate is nature water seal (i.e. water level is down to nature water seal water bit line).Therefore, key existing for water curtain system exists
In needing to carry out moisturizing in time according to the SEA LEVEL VARIATION of underground water, and in the prior art, generally use the recharge well on ground to
Moisturizing is carried out in water curtain tunnel, however, there are a serious technical problems for ground moisturizing: the water quality requirement of moisturizing is higher, leads to
Often needing could be to groundwater feed after specially treated, and needs special treatment facility, is otherwise easy to cause over the ground
The pollution of lower water environment, in addition, the water to supply water must be also sufficiently ensured, therefore the long-term fortune of current method for supplementing water
Row cost is excessively high.
In the prior art, Chinese patent CN104763449B discloses a kind of underground water seal cave depot water curtain system design side
Method, comprising steps of carrying out the design of water curtain tunnel after the completion of geology is surveyed in detail, main cavern designs and traffic tunnel is designed；Carry out water
It puts down and is designed to water curtain hole and vertically to water curtain hole；Installing intersection is done to fault belt developmental state；Water curtain roadway excavation at
After type, main cavern position soft rock mass pretreating scheme design is carried out；It all constructs and finishes in the water curtain hole in some water curtain tunnel
Afterwards, pressure water injection test is carried out to all water curtain holes in the tunnel；Closure conceptual design is done to the seepage channel of discovery.The present invention
Horizontal direction water curtain hole depth greatly reduce, drilling construction difficulty is low；It is pre- to main cavern position soft rock mass by water curtain tunnel
Slip casting advantageously ensures that construction speed, reduces construction risk；Leakage passage slip casting is blocked, can prevent or reduce main cavern to open
Underground water when digging is lost, and guarantees the water seal environment on main cavern periphery.For another example, Chinese patent application CN105545359A is disclosed
A kind of water filling conducting device in water seal cave depot connection tunnel and water curtain tunnel, comprising: sealing-plug；Tunnel is connected, in vault
Meta position has installed via hole A；Water curtain tunnel is set on the bottom plate in the water curtain tunnel positioned at the external top in the connection tunnel
There is via hole B；Waterpipe is each passed through the via hole A and via hole B, connects the connection tunnel and water curtain tunnel；It is described
The bottom end of waterpipe passes through the via hole A and extends downwardly, and length >=50cm of extension；Manhole is arranged in underground work
Journey exports on the sealing-plug of side, and the manhole uses blind plate sealing.
In addition, the utility model patent CN204457869U of Tsinghua University provide a kind of underground water seal cave depot water curtain hole from
Dynamic flood pattern, wherein collection control unit is sequentially connected in series by control line and several measurement and control units, and is arranged in collection control unit
Main control computer；Meanwhile collecting control unit and being connect by wired or wireless network with host computer；One of water pipe section in measurement and control unit
End is connect with water inlet pipe, and the other end is connect with outlet pipe；The outlet of outlet pipe passes through water filling sealing of hole embolism and underground water seal cave depot
Water curtain hole be tightly connected；In water pipe section in the measurement and control unit along water (flow) direction set gradually solenoid valve, flow sensor,
Pressure sensor；Solenoid valve, flow sensor and pressure sensor in each measurement and control unit pass through RS485 connection and collection respectively
Control the main control computer connection in unit；The utility model realizes the automatic control to water curtain hole water filling overall process, and control is quasi-
Exactness and measurement accuracy are high, and can be to charging state remote real-time monitoring.
It can be seen that the prior art can not effectively solve the long-term active moisturizing process of underground water seal cave depot water curtain system
The high technological deficiency of middle operating cost.
Summary of the invention
In order to make full use of the function and structure feature of underground water seal cave depot, while making full use of the intrinsic underground water hydrology
