Description
Technical field
The invention belongs to be layered the technology of drawing water more particularly to a kind of water-stop applied to geothermal well bailing test, layering
Antipriming and system.
Background technique
Currently, the distribution characteristics and watery for finding out water-bearing layer are for ground water development when carrying out Hydrogeological Work
Using being of great significance.It is the complicated water storage geologic province such as multi-layered aquifer and block water-bearing section in underground water, different contains
Water layer, water level, water quality and various hydrogeological parameters are all different, and need to complete water by drilling layering bailing test
Literary geological test.Only need a drilling that can be oozed out water-bearing interval in the suction eye being located in the different depth section of stratum
Water it is independent extract, the different depth section so as to rapid and inexpensive understanding specific position stratum includes
The hydrogeological characteristics of water layer section, therefore become the technology being commonly used in Hydrogeological Work.
By design requirement in water barrier position, isolation sealing is carried out to water-bearing layer above and below drilling well, prevents water-bearing layer string up and down
It is logical to carry out layering sealing, it is an important technique in layering bailing test.Traditional sealing mode applies vehicle band tire, Huang more
Beans, kelp etc. block sealing position, since sealing position can not be monitored in underground, need operator's experience rich
It is rich, technical level is high, it is improper otherwise to may cause sealing position, degree, mentions the problems such as brill can not be normally carried out, influences layering and take out
Water test is normally carried out.Therefore subsequent to start inflation water-stop occur, lower underground is automatically recorded by the monitoring system of outfit
The situation of water variation, is monitored its plugging effect, but earth's surface inflation system, inflation must will be arranged in this kind of sealing mode
Charging circuit needed for pipeline and monitoring system etc., uncontrollable factor is excessive, especially inflation line, charging circuit danger coefficient
Height once winding, can not mention brill, hardness mentions brill and had both been likely to cause inflation line, charging cable path loss during tripping in
It is bad, and may be because and significantly disturb the damage for causing unrepairable to drilling well, consequence is difficult to handle, especially drilling depth
It is very deep, such as the geothermal well of 400m or more, for 1000m or more geothermal well more very, if winding, deal with even more difficult
It is heavy, thus while can be monitored by monitoring system using the water-stagnating effect of inflation water-stop, but thus bring
Problem but becomes the main interference factors that entire layering bailing test is normally carried out, and causes user usually because of thus bring
Consequence gives up this sealing mode, its advantage is made to have no chance to play.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of the present invention is to provide a kind of stopping applied to geothermal well bailing test

Same material, air bag 6 are also distinguished between water guide tube body 5 and plasticity protective layer 7 between water guide tube body 5, plasticity protective layer 7
Support frame 9 and elastomer 10 are set.Water guide tube body 5 and plasticity protective layer 7 are fixed by support frame 9, pass through elastomer 10 such as bullet
Spring connection facilitates the recovery of plasticity protective layer 7, bores convenient for mentioning, support frame 8 and elastomer 9 can after the disappearance of 6 expansionary force of air bag
It is multiple to be arranged, it is uniformly distributed between water guide tube body 5 and plasticity protective layer 7, the quantity of air bag 6 is preferably multiple, and such as 4,
It is distributed between a support frame 9 and 10 assembly of elastomer and 10 assembly of another support frame 9 and elastomer.The plasticity is protected
Sheath 7 is bonded setting with plastic circle 8, and is located at 8 inside of plastic circle, and the specific top and the bottom in outer surface of the plasticity protective layer 7 are equal
Sensor module 11, signal emission module are installed respectively, need to be arranged protection outside certain sensor module 11, signal emission module
Shell protects it, and sensor module 11, the quantity of signal transmitting mould are generally identical as 6 quantity of the air bag of setting, sensing
By the deformation data for acquiring plasticity protective layer, to be specially bending degree be conveyed to surface data by signal to device module 11 handles
Whether device calculates the enlarged degree of external plastic circle 8 according to the bending degree of plasticity protective layer 7, completely stifled for checking
Water, the sensor module 11 are specially gyroscope equipment.
6 memory storing gas reactant of air bag, the gas generated by gas reactant reaction, rather than inflated by earth's surface and be
System, therefore the configuration of earth's surface inflation system and its inflation line is eliminated, the preferred CO of the present embodiment2Air bag 6 is inflated, table 1 is passed through
It is found that CO2The compressed coefficient of the gas at 10MPa (1000m) is about 0.54, and theoretically 2L volume reagent can at least release
200L or more carbon dioxide, and the volume of 100L or more can be propped up under 10Mpa pressure.Bulk gas makes air bag 6, and (air bag 6 makes
Made of high-strength materials such as air tubes) expansion rapidly.CO2Critical-temperature be 31 DEG C or so, that is, temperature be higher than 31
DEG C, intensified pressure will not liquefy, therefore pass through CO2Operating environment be suitable for 400m or more depth geothermal well, especially
The geothermal well of 1000m or more.
Table 1: the compressed coefficient of carbon dioxide
It is arranged in air bag 6 for storing multiple CO2The storage space 12 of gas reactant is equipped with vent valve 13 on air bag 6,
The wireless sonar vent valve of vent valve 13 can be specifically disposed at 6 fixing port of air bag, make it that can open gas after experiment terminates
