Description
Technical field
The present invention relates to a kind of methods for extracting salt lake mining area brine, more particularly, to a kind of increase salt lake mining area halogen mining well
The method of halogen amount out.
Background technique
Salt lake mining area brine ore bed is generally divided into latent brine ore bed and pressure bittern mine according to water-bearing layer bearing features difference
Layer, wherein latent, brine ore bed buried depth is shallow, infiltration coefficient is big, watery is good, and pressure bittern ore bed buried depth is big, infiltration coefficient is small, rich
Aqueous difference, pressure bittern ore bed latent brine ore bed because thickness is much larger than, therefore its porosity and specific yield stock number are generally higher than
Top is dived brine ore bed.The main exploitation object in most domestic salt lake mining area is that superficial part is dived brine ore bed at present, but with landing
The lower large-scale drainage formula of brine is exploited, and the latent brine seam thickness in stratum is thinning year by year, and that respectively adopts halogen engineering actually adopts halogen
Ability is also successively decreased year by year, finally makes latent brine deposit depleted, and then be unable to satisfy corresponding production scale.Therefore, inside state
The recovery method for dividing mining production enterprise to have begun exploring deep layer pressure bittern ore bed.For deep layer pressure bittern (brine face
Buried depth is at 30 meters or more), it is general at present to adopt halogen by the way of deep well pump using beating vertical deep-well and set in well, but due to deep
The infiltration coefficient and specific yield of pressure bittern layer are smaller, and it is lower to go out halogen amount using individual well when the above method, same to meet
Manufacturing specification request, then need more halogen mining wells, and production cost is higher.Therefore, how to improve the infiltration of Deep Confined brine layer
Saturating and connectivity, so that the halogen amount that goes out that halogen engineering is adopted in increase is the big technical problem faced at present.
Summary of the invention
The technical problem to be solved by the present invention is to salt lake mining area can be increased by overcoming the deficiencies of the prior art and provide one kind
The method that halogen mining well goes out halogen amount.
The technical solution adopted by the present invention to solve the technical problems is: a kind of increase salt lake mining area halogen mining well goes out halogen amount
Method, comprising the following steps:
(1) vertical deep-well is built
The projected depth of vertical deep-well is determined according to halogen ore bed occurrence condition, shaft bottom should be located at the quasi- exploitation halogen ore bed of lowest part
Bottom plate below 5~8m；
(2) directional horizontal wellss are built
Since the exploitation of pressure bittern layer generally carries out from top to bottom, directional well is passed through after overlying rock along pressure bittern mine
The construction of bottom plates horizontal segment of layer I, and be connected to vertical deep-well；
(3) layer exploitation is changed
When top pressure bittern layer I go out halogen amount reduce, when manufacturing specification request is not achieved, directional well steady tilted section can be continued to
Lower deepening then continues the construction of bottom plates horizontal segment along pressure bittern layer II；Continue back production lower part pressure bittern layer by this step,
And it is connected to vertical deep-well.
Further, in step (1), the diameter of well is 800~1000mm.
It further,, should be in the full well of vertical deep-well when interlayer between halogen ore bed and unstable upper formation in step (1)
Setting of casing retaining wall in section, and sieve pore is set in halogen well section out, shaft bottom sets deep well pump halogen.
Further, in step (1), when horizontal segment goes out, halogen amount is larger (to be greater than 1000m3/ h) when, it can suitably increase by 1~2
Vertical deep-well is connected to horizontal segment.
Further, in step (2), the aperture of horizontal segment is 600~800mm, and length is 600~1000m.
Further, in step (3), the aperture of horizontal segment is 600~800mm, and length is 400~800m.
Using the present invention, can expand deep layer pressure bittern layer goes out halogen area, and increase vertical deep-well adopts halogen amount, economy effect
It is beneficial significant, also achieve the purpose that make full use of salt lake bittern resource.
Detailed description of the invention
Fig. 1 is that the embodiment of the present invention adopts halogen schematic diagram.
Specific embodiment
Below in conjunction with drawings and examples, the invention will be further described.
Embodiment 1
Referring to Fig. 1, the present embodiment the following steps are included:
(1) vertical deep-well is built
The projected depth of vertical deep-well 1 is determined according to halogen ore bed occurrence condition, shaft bottom is located at the quasi- working seam-of lowest part and holds
The bottom plate of brine layer II 3 or less 5m is pressed, the diameter of well is 1000mm；Since stratum is more stable, in this embodiment not under
Casing retaining wall；Match deep well pump halogen in vertical well lower part；
(2) directional horizontal wellss are built
The mining area is contained altogether can exploit pressure bittern layer for two layers, and when exploitation first adopts upper layer pressure bittern layer I 2；Therefore directional well is worn
More after overlying rock 4, along the construction of bottom plates horizontal segment 7 of pressure bittern ore bed I 2, the aperture of the horizontal segment is 600mm, and length is
1000m, and be connected to vertical deep-well；
(3) layer exploitation is changed
With continuing for exploitation, the halogen amount that goes out of top pressure bittern layer I is gradually reduced, and production-scale requirement is not achieved,
Directional well steady tilted section 6 is continued into downward deepening at this time, is continued after passing through the interlayer of interlayer containing pressure bittern 5 along pressure bittern layer II 3
Construction of bottom plates horizontal segment 7, see dotted portion in figure, the aperture of the horizontal segment is 600mm, length 600m, and with vertical depth
Well connection.
Using the present invention, can expand deep layer pressure bittern layer goes out halogen area, and increase vertical deep-well adopts halogen amount, economy effect
It is beneficial significant, also achieve the purpose that make full use of salt lake bittern resource.
