Abstract
The present invention relates to a drilling water-dissolving exploiting method for soluble salt type salt bed mineral resources. The present invention integrally arranges production wells on the positions of salt bed fixed points not dispersedly distributed on the surfaces of salt beds, uses the all-around exploitation of large-area salt beds, and does not uses basic methods in which separate exploitation by dividing wells and well groups is carried out or exploitation is communicated after the separate exploitation by dividing wells and well groups. The exploiting method can greatly save exploiting construction, reduce cost, increase efficiency and increase exploiting rate; the exploiting method is favorable for salt containing combined exploitation with multiple salt beds and the exploitation of salt beds with large exploiting inclination angle and complicated structure. The present invention is used for exploiting potassium salt beds, rock salt layers, natural alkali, mirabilite beds, etc.
Description
The present invention is a kind of drill well water mixeding mining method of lyotropic salt class salt deposit mineral reserve, is that a kind of improved salt deposit drilling well hydromining is communicated with water-soluble method.The present invention is suitable for producing potassium salt layer, halite layer, trona and chuco etc.
From the water-soluble mining codes of the inorganic salt deposit of underground mining is very much popular now in the world.
The salt deposit mineral reserve drill well water mixeding mining method that now grows up in the world, a water-soluble method in molten chamber (individual well convection current method, lubricating pad method etc.) for the individual well exploitation, one is the water-soluble method of connection of the higher well group connection exploitation of efficient.
Individual well convection current method, i.e. the method that disclosed of John Higgins (Higgins) because efficient is low and yield poorly, is now seldom used.
The water-soluble method of the connection of well group connection exploitation also proposed in the disclosed patent document of John Higgins.Because this method has improved efficient, now generally adopt.This method is exactly the water-soluble method of existing connection.
The water-soluble method of existing connection also has following two problems:
(1) dispersed placement producing well on the face of salt deposit, exploitation engineering is too huge.
(2) salt deposit divides well group to cut apart exploitation, and being limited in scope of connecting dissolution can not be given full play to the positive role that is communicated with hydromining, stays between well group simultaneously and much do not adopt surplus ore deposit.
The objective of the invention is to solve above-mentioned two problems, avoid the branch well group to cut apart exploitation, realize that the complete connected sum of large tracts of land salt deposit is exploited comprehensively, thereby improve production efficiency greatly, save exploitation engineering, improve recovery ratio.
Method of the present invention is:
(1) from some place, the salt deposit structure end, produces the salt of whole salt deposit.
Principle constantly floats for the clear water of injection, and the dissolving salt deposit forms and is bittern, and bittern constantly sinks to salt deposit structure bottom again and is produced.
(2) if the part of exploitation salt deposit is then selected the salt that the place produces this entire portion salt deposit from this part salt deposit structure end.
The part salt deposit of being exploited should be the above salt layer segment of a certain height of this salt deposit.The salt deposit subsurface contour of this height is at the bottom of the structure of this part salt deposit.Point at the bottom of the suitable structure that a bit promptly can be used as this part salt deposit at the bottom of the structure of this part salt deposit.
(3) be arranged in producing well set on the salt deposit structure end point place or on the part salt deposit structure end point place.
(4) also can be arranged on the arbitrary fixed point of the salt deposit place salt to producing well set with the updip salt deposit of producing this fixed point.
(5) for obtaining better effect, water injection well should be arranged in the salt deposit updip direction of producing well, is preferably arranged on the salt deposit countertendency of producing well, is preferably arranged on the salt deposit countertendency of producing well of inclination angle maximum.
(6) for obtaining better effect, producing well should be arranged in by on salt deposit fixed point or the salt deposit subsurface contour by salt deposit or part salt deposit structure end point, if the salt deposit structure end is a point, then producing well should be arranged near on the salt deposit subsurface contour of putting at the bottom of this structure.
Be an embodiment of the inventive method below:
Be provided with a salt deposit, little, the closed syncline structure, the northern wing is steep, Nan Yihuan.
The producing well set is arranged on wedged bottom point place, specifically is arranged near putting on the salt deposit subsurface contour of the wing by north to wedged bottom, well spacing can be about 50 meters.
Water injection well is arranged in the northern wing, on the salt deposit countertendency of producing well, can be about 100 meters apart from producing well.If also need another water injection well, then be arranged in and arrange the same direction of previous water injection well to extend out, can be about 100 meters from previous water injection well.If also need water injection well then by that analogy.
Producing well and water injection well are communicated with Splitting Method or dissolution method.
The invention has the advantages that:
(1) the present invention arranges less producing well at salt deposit fixing point place upper set, arranges in addition less water injection well, has so just greatly simplified exploitation engineering.
(2) the present invention can further improve recovery ratio to the comprehensive connecting dissolution of large tracts of land salt deposit, comprehensively exploitation. The degree of enhanced oil recovery can be close to 100%.
(3) the present invention is communicated with recovery well fully from start to finish and takes the comprehensive connection exploitation of large tracts of land salt deposit, can give full play to the positive role that is communicated with hydromining. This just for greatly improve production efficiency and greatly reduce Ground Operation, ground surface works has been created condition. This point is a cardinal principle of the present invention and basic advantage.
(4) water injection well of the present invention is arranged on the salt deposit countertendency of producing well, can make distance weak point, the salt deposit discrepancy in elevation of water injection well and producing well big. The two is conducive to be interconnected apart from short, and the salt deposit discrepancy in elevation greatly then is conducive to fall to the bittern of producing well and top clear water is separated. And be conducive to clear water and rise rapidly and enlarge the scope that dissolving is communicated with, the bittern rapid decrease is in producing well. The result who arranges like this, production effect is fabulous.
(5) the present invention is conducive to link up interlayer and is communicated with owing to very big in the scope of underground connecting dissolution, can be that the division of many salt deposits separate zone production level is bigger, less to saliferous, merges exploitation to enlarge many salt deposits, and minimizing exploitation engineering amount improves production efficiency.
(6) the present invention utilizes salt deposit structural deformation condition consciously, to bring into play and to utilize underground hydromining to move both vertically, not only can exploit better mild, simply constructed salt deposit, and more favourable exploitation inclination angle is big or the salt deposit of complex structure.
Claims (7)
1, a kind of drilling well hydromining of lyotropic salt class salt deposit mineral reserve is communicated with water-soluble method, water injection well is communicated with underground with producing well, thereby constantly inject clear water and output bittern and realize the circulation exploitation, feature of the present invention is that producing well set is arranged on the salt deposit fixed point place, and realizes that thus the complete connected sum of large tracts of land salt deposit exploits comprehensively.
