Abstract
The invention provides a control method of interlayer rock salt cavern building with water solution in an underground oil and gas storage, which overcomes the defects and shortcomings of total collapse risks caused by pressure surge of the conventional single-well oil pad water solution process which cannot control the shape of the cavern in the interlayer rock salt, is applicable to interlayer rock salt cavern building with water solution in the underground oil and gas storage, easily controls the shape of the cavern, reduces the risks of pressure surge caused by total falling of the interlayer and improves the cavern building efficiency. The control method is characterized in that by utilizing the expansion and disintegration of the mud shale interlayer under wet-dry cycling condition and adopting the cavern building method with water solution of cycling injection by fresh water and dry air, the gradual dropping of the mud shale interlayer is accelerated, the cavern building efficiency is improved, the shape of the cavern can be controlled through adjusting the cycling injection time interval, and the storage collapse caused by total falling of the interlayer is avoided.
Description
Technical field rock salt underground oil and gas bank is made the chamber technical field
The current rock salt underground oil and gas of background technology bank is built storehouse individual well lubricating pad water soluble method commonly used, by dual string combination, successively molten drench from bottom to top, the water-soluble chamber of making of direct circulation.This method is for salt dome type stratum, molten chamber form with easy formation design, the good advantage of molten chamber roof stability, but for containing stratiform rock salt with dissection stratum, interlayer has preferably continuity more, certain thickness is arranged, be water-fast mud shale, traditional individual well lubricating pad water soluble method can not dissolve when running into interlayer, has limited border, molten chamber, can not form the molten chamber form of design, when the free face of interlayer bottom surface stripping one fixed width, whole interlayer has the danger of whole inbreak, and easily mineralization pressure is exciting, causes whole cavity unstability to be caved in.
Therefore, current individual well lubricating pad water soluble method commonly used can not satisfy and contains interlayer rock salt underground storage to the cavity proterties control demand with stability.
Summary of the invention the invention provides and a kind ofly overcomes traditional individual well lubricating pad On The Deliquescentt Technics can not control molten chamber form in containing the interlayer rock salt, the pressure excitement causes the shortcoming and defect of total collapse risk, be applicable to contain the water-soluble chamber of making of interlayer rock salt underground storage, molten chamber easy to control form, reduce the danger of the whole inbreak mineralization pressure of interlayer excitement, improve make chamber efficient contain the water-soluble chamber control method of making of interlayer rock salt underground storage.It is characterized in that utilizing the expansion and disintegration of mud shale interlayer under the drying and watering cycle condition, adopt fresh water and the dried air circulation of making an uproar to annotate the water-soluble cavity method of making of adopting, accelerate progressive the dropping of mud shale interlayer, improve and make chamber efficient, can annotate the time interval of adopting by the adjustment circulation simultaneously and control molten chamber form, avoid the whole inbreak of interlayer to cause bank to cave in.
Contain the water-soluble main technical schemes of making the chamber control method of interlayer rock salt underground storage and be divided into three part formations: contain interlayer rock salt underground storage feature, make the chamber device, make chamber control technique.Containing interlayer rock salt underground storage is characterized as: in the salt rock stratum 2 that contains mud shale interlayer 3 of overlying strata 1 was arranged, the underground oil and gas bank designed molten chamber form 11; Making the chamber device is protection tube 6, ascending pipe 5 and extraction pipe 4; Making chamber control technique is: inject protective agent 9 in protection tube 6, inject infusion 8 in the ascending pipe 5, extraction production 7 in the extraction pipe 4, infusion 8 are that fresh water and dry air alternately inject, and production 7 is bittern or wet air.
Basic principle and technology: mineralogical composition and water according to the mud shale interlayer in the rock salt stratum are managed characteristic as can be known, essential mineral in the mud shale interlayer is clay mineral, wherein montmorillonite and chlorite have Expansion and disintegration, under the ambient conditions of alternation of wetting and drying, has stronger water sensitivity characteristic, montmorillonite and chlorite mineral expansion and disintegration cause the mud shale structural deterioration, thereby gradual slabbing disintegration occurs to be destroyed, promoted that the progressive of mud shale interlayer drops, improved and made chamber efficient, the risk of also having avoided the whole inbreak of interlayer to cause bank to cave in, simultaneously can be by adjusting the molten chamber alternation of wetting and drying time, control mud shale interlayer drop speed and rock salt dissolution velocity, thus molten chamber form controlled.
Contain the water-soluble main technical schemes of making the chamber control method of interlayer rock salt underground storage and be divided into three part formations: contain interlayer rock salt underground storage feature, make the chamber device, make chamber control technique.
Containing interlayer rock salt underground storage is characterized as: in the salt rock stratum 2 that contains mud shale interlayer 3 of overlying strata 1 was arranged, the underground oil and gas bank designed molten chamber form 11.
Making the chamber device is protection tube 6, ascending pipe 5 and extraction pipe 4; From boring, be lowered to protection tube 6, protection tube 6 built-in ascending pipes 5, ascending pipe 5 built-in extraction pipes 4.
Making chamber control technique is: inject protective agent 9 in protection tube 6, inject infusion 8 in the ascending pipe 5, extraction production 7 in the extraction pipe 4, infusion 8 are that fresh water and dry air alternately inject, and production 7 is bittern or wet air.
Description of drawings 1: overlying strata; 2: the salt rock stratum; 3: the mud shale interlayer; 4: the extraction pipe; 5: ascending pipe; 6: protection tube; 7: production; 8: infusion; 9: protective agent; 10: actual molten chamber form; 11: design molten chamber form; 12: mud shale interlayer joint fissure
The specific embodiment 1. is used to pierce design bank bottom forming hole in the salt rock stratum 2 that contains mud shale interlayer 3 of overlying strata 1 is arranged.
2. from boring, be lowered to protection tube 6, protection tube 6 built-in ascending pipes 5, ascending pipe 5 built-in extraction pipes 4.
3. in protection tube 6, inject protective agent 9, inject infusion 8 in the ascending pipe 5, extraction production 7 in the extraction pipe 4, infusion 8 is the injection that hockets of fresh water and dry air, production 7 is bittern or wet air.Loop alternately to annotate and adopt, cause mud shale interlayer 3 expansion and disintegrations, produce more mud shale interlayer joint fissures 12, the mud shale interlayer is progressive to drop, improve and to make chamber efficient, adopt the time by adjusting alternately to annotate, control mud shale interlayer drop speed and rock salt dissolution velocity, thereby control molten chamber form, the risk of avoiding the whole inbreak of interlayer to cause bank to cave in.
