Abstract
The utility model relates to a cable core-taking air-pressure type water-pressing embolism, which belongs to the equipment for a water-pressing test in cable core-taking drilling technology. An upper joint is threadedly connected with a water inlet joint; the water inlet joint is threadedly connected with an air bag upper joint; an O-shaped sealing ring I is provided between the water inlet joint and the air bag upper joint; one end of an air pipe is connected with the upper joint, and the other end is connected with the water inlet joint; the water inlet joint is threadedly connected with a core pipe; two ends of a high pressure capsule are respectively connected with the air bag upper joint and the air bag lower joint by compression joint; the high pressure capsule forms an air chamber with the outer side of the core pipe; the air bag lower joint is slidingly connected with the core pipe; and an O-shaped sealing ring II and a dustproof ring are provided between the air bag lower joint and the core pipe. The cable core-taking air-pressure type water-pressing embolism is advantageous in that the structure is novel, the core-taking effect is good, the production efficiency is high, the drilling cost is low, and the failure rate is low.
Description
Technical field
The utility model belongs to the equipment that carries out packer permeability test in the wire line coring drilling process.
Background technology
Water pressure test in borehole is the hole section that will hole and isolate certain-length with embolism, and to this hole section setting-out, confirms a kind of original position permeability test of rock mass Penetration Signature according to the relation of pressure and flow.
It is that a kind of need not carrying bored and can directly be obtained the advanced drilling method of rock core that wire line coring creeps into.Compare advantage such as it is effective to have a core of getting, and production efficiency is high, and drilling cost is low with common drilling method.
Water conservancy and hydropower geologic prospect boring will be done packer permeability test mostly; Use traditional setting-out embolism to propose boring to drill rod boring tool; The superiority that wire line coring creeps into can't be brought into play, so this advanced person's of wire line coring drilling technology can not obtain promotion and application in the water conservancy and hydropower probing.
Summary of the invention
The utility model provides a kind of wire line coring vapour-pressure type setting-out embolism, proposes the problem that the core effect is got in the boring influence to drill rod boring tool when getting core with solution.
The technical scheme that the utility model is taked is: top connection is threaded with water supply connector; Water supply connector is threaded with the air bag top connection, and " O " RunddichtringO one is arranged between water supply connector and air bag top connection, and tracheae one end is connected with top connection, the other end is connected with water supply connector, and water supply connector is connected with the core pipe thread; High pressure capsule two ends respectively with air bag top connection, air bag lower sub crimping, high pressure capsule and the core pipe outside forms air cavity, air bag lower sub and core pipe are slidingly connected, and " O " RunddichtringO two and dust ring are arranged between air bag lower sub and the core pipe.
The advantage of the utility model is: novel structure, and it is effective to get core, and production efficiency is high, and drilling cost is low, and failure rate is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The working method of the utility model is: through wire line coring drilling rod, drilling tool with the setting-out vent plug down to test section, air bag partly is exposed to outside the drilling tool.With air pump or welding bottle air feed, pressure gas is given the inflation of high pressure capsule from high-pressure rubber pipe through top connection 1, tracheae 3, air bag top connection 4, and air bag expands test section and drilling tool inboard are sealed simultaneously.Press water is through drilling rod, and the opening of water supply connector 2, core pipe enter into the packer permeability test section and carry out packer permeability test.High pressure capsule 5 is the novel capsule of nexine folder reticulate texture steel wire, and burst pressure is greater than 24MPa, and expansivity can reach 300%, has solved low, the explosive problem of common setting-out capsule compressive resistance effectively; Open design are adopted in water supply connector 2, and water directly gets into the core pipe through the opening of drilling rod through water supply connector 2 and carries out setting-out, need not to insert special water pipe, and is simple in structure; High pressure capsule 5 long 1.5m, once inflation seals drilling tool and hole wall simultaneously, simplifies the structure.
