Description
Technical field
The present invention relates to the exploitation of underground salt mine and oil storage and transportation technology field.
Background technology
Because rock salt has good sealing, hypotonicity and damages self-healing so that deep underground salt mine turns into
A kind of main medium of countries in the world underground storage.Underground energy repository is built using rock salt to have many advantages, especially weigh
Want be it is safe, be advantageous to war preparedness, be referred to as " warehouse of height strategic security ".Stratum is built in respect to foreign countries
Warehouse in the huge thick Salt layer of simple structure is compared, and the Salt layer of China is usually that salt deposit is thin, interlayer is more, grade is low, salt
There are a large amount of water insoluble impurity in layer, its main component is the carbonate and organic remains of sand, clay, calcium and magnesium,
When building chamber using drilling solution method, these water insoluble impurity can largely be retained in underground, and these leave the insoluble matter of underground,
Also known as insoluble residue thing, certain cavity space volume can be also occupied, that causes sometimes adopts halogen channel blockage.Existing solution is done
Rule is had to upper lifting pipe post, so as to influence cavity to form and make chamber speed.Such as in sinopec Jintan gas storage, the water of salt deposit is not
Molten thing average content is 15%, and the idle space in a new molten chamber of 250,000 sides just reaches 50,000 sides, accounts for total measurement (volume) 1/5, current salt
Rock underground storage underground engineering investment individual well preliminary design expense more than 7,000 ten thousand.
China just starts in terms of rock salt underground storage construction, and rock salt underground storage insoluble residue thing is not yet directed at present
Removing carried out relation technological researching, and technology is among blank.
The content of the invention
For the problem present on, the present invention seeks to propose the salt used by a kind of suitable petroleum gas accumulating field
Rock underground storage underground insoluble matter removes system.
The present invention includes the intervalve being arranged in the production casing of underground, and the side wall of intervalve passes through connecting tube and switch valve
It is connected with the liquid outlet of drilling fluid pump, the inlet of drilling fluid pump is connected on drilling fluid pot, it is characterised in that：In intervalve
Central tube is nested with, reducing mechanism is connected by drilling tool in the lower end of central tube, connecting ascending pipe in the upper end of central tube goes out liquid
End, is connected on the exit port of drilling fluid pump by the liquid feeding end of the ascending pipe, the upper end sealing of intervalve connects on the top of intervalve
Chip recovery tube is connect, in the empty air pressure inlet of side wall connection of intervalve.
The vibratory sieve with small opening is set in the top of the drilling fluid pot, scrap collecting is set in the side of vibratory sieve
Tank, the port of export of the chip recovery tube is arranged in the top of vibratory sieve.
The present invention is another object is that propose application of the system above in the removing of rock salt underground storage underground insoluble matter：
The switch valve is closed, drilling fluid pump is opened, drilling tool is set in working order, and it is continuous in by empty air pressure inlet
Between pipe and central tube between annular chamber connection be passed through pressure-air, you can chip recovery tube the port of export obtain chip with bore
The mixture of well liquid.
Further, the mixture of chip and drilling fluid is by after the effect of vibratory sieve small opening, drilling fluid reclamation is in drilling well
In liquid pool, while solid debris are collected in scrap collecting tank.
Operation principle of the present invention is：In production pipe, central tube and the pipe flow of intervalve three, brill is noted using from production pipe is counter
Hydraulic thrust, the negative pressure pumping of intervalve formation and the reducing mechanism that well liquid is formed form the collective effects such as eddy flow, will be deposited on
Water insoluble accumulation of impurities in the larger space of shaft bottom is to around reducing mechanism（This is the key point for distinguishing oil drilling）.
Reducing mechanism smashes the water insoluble impurity for depositing in the presence of drilling tool, during due to ground drilling liquid pump, drilling fluid is passed through
Heart tube pump enters in the rock salt underground storage under, so chip after smashing is then together with drilling fluid mixed, or even forms energy
Suspend.Due to being continuously injected into for pressure-air, and the top of the intervalve in sealing is connected with chip recovery tube again, so
Negative pressure is formed in annular space chamber between central tube and intervalve, the negative pressure is then by the mixing of drilling fluid and chip in the way of pumping
Thing is carried to ground.
The present invention is simple and reasonable for structure, and operating process is simple, and continuity is good, low cost, can high-efficient cleaning except the storage of rock salt underground
Storehouse insoluble residue thing, can reach the purpose for removing salt hole air reserved storeroom underground insoluble matter with reciprocation cycle.
Further, the present invention was also carried out by vibratory sieve removing to the mixture of pumping drilling fluid out and chip
Filter sub-sieve, the drilling fluid for removing underground insoluble matter chip is collected in drilling fluid pot again, and underground is pumped into circulate, while
Solid debris are focused on.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the invention.
Specific embodiment
Structure of the present invention is middle as shown in figure 1, present system is provided with the intervalve 5 being arranged in underground production casing 6
