Description
Technical field
The utility model relates to engineering investigation equipment, and particularly a kind of wire line coring boring is not carried and bored special-purpose packer permeability test embolism.
Background technology
In the engineering investigation work, it is a kind of drilling technology very efficiently that wire line coring creeps into.In drilling process, after core is full of core barrel, need not propose big core-drilling, but be passage with the drilling rod, by means of special-purpose fishing tools such as ropes, the core in the pipe rises to outside the hole in the core being stored in the drilling process.Because this method does not need all drilling rods are risen to outside the hole, so greatly reduced the time of drilling, has reduced labour intensity significantly yet.This technology is at mineral products, and industries such as coal, oil have obtained using widely, have obtained significant effect.
But the Hydraulic and Hydro-Power Engineering exploration is owing to the singularity of himself, and the wire line coring drilling technology does not obtain excellent popularization, and main cause is water conservancy and hydropower exploration need carrying out usually packer permeability test on-the-spot in-situ tests such as (being a test section with 5m generally); Existing water-pressurizing test method is lowered to setting-out embolism and water filling conduit after normally after examination section is crept into end drilling rod all being proposed boring again, tests then, and therefore, this test routine and method are difficult to the advantage that the performance wire line coring creeps into.Creep into the advantage of not carrying wammel in order to bring into play wire line coring, many surveying unit adopt and creep into 30m, carry wammel then, do packer permeability test with two embolisms, and whether the embolism that this method is difficult to check the bottom are difficult to guarantee the quality of packer permeability test fully by shutoff.If can be in conjunction with the characteristics of water conservancy and hydropower exploration, design a kind of packer permeability test embolism of not carrying wammel, just can address the above problem, thereby in the water conservancy and hydropower exploration engineering, will be the technical matters of desired solution in the industry well this efficient drilling technology graft application of wire line coring.
Goal of the invention
At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just provides a kind of wire line coring boring and does not carry the special-purpose packer permeability test embolism of brill, can effectively solve embolism fully by shutoff, guarantee the quality of the hydraulic testing, do not put forward the advantage problem of brill to give full play to wire line coring.
The technical scheme that the utility model solves is, comprise core pipe, steel sleeve and high pressure capsule, the high pressure capsule is made up of the top high pressure capsule and the bottom high pressure capsule that are contained on the core pipe outside, top high pressure capsule and bottom high pressure capsule are linked together by steel sleeve, the air hole gland is equipped with in high pressure capsule end, top on the core pipe, bottom high pressure capsule and O type circle is arranged on the core pipe with the sliding bolt gland, extension spring is equipped with in sliding bolt gland outside on the core pipe end, extension spring is equipped with spring bottom set bolt through spring pretension regulation cock.
The utility model is simple in structure, and is novel unique, long service life, and cost is low, and result of use is good, is the innovation on the engineering investigation equipment.
Description of drawings
Fig. 1 is the semi-section front view of the utility model structure.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
By shown in Figure 1, the utility model comprises core pipe, steel sleeve and high pressure capsule, the high pressure capsule is made up of the top high pressure capsule 2 and the bottom high pressure capsule 5 that are contained on the core pipe outside, top high pressure capsule and bottom high pressure capsule are linked together by steel sleeve 4, air hole gland 1 is equipped with in high pressure capsule end, top on core pipe 3, bottom high pressure capsule and O type circle 6 is arranged on the core pipe with sliding bolt gland 7, extension spring 10 is equipped with in sliding bolt gland outside on the core pipe end, extension spring is equipped with spring bottom set bolt 9 through spring pretension regulation cock 8.
In order to guarantee result of use, on the described steel sleeve 4 evagination step 11 is arranged, there are rotatable joint and the suspension ring 12 that place outside the air hole gland 1 described core pipe 3 ends.
By said structure as can be seen, the utility model is:
(1) the embolism center is the core pipe of one whole through hole, and the core tube outside is the high pressure capsule.The high pressure capsule is divided into up and down two parts, and lower diameter is all less than the internal channel (the minimum place of passage is step in the drill bit) of core plugging notifying mechanism of rope core drilling.Top and the bottom link to each other by steel sleeve, process a bigger step on the steel sleeve, make it not play position-limiting action by step in the drill bit.Simultaneously this steel sleeve can guarantee that capsule expands up and down, synchronization telescope during release, and cut by drill bit can prevent that capsule from expanding the time.
(2) the capsule bottom is the prestressed extension spring of scalable, and effect is to help to restore fast after the embolism release.
(3) embolism top is suspension ring and rotatable joint.Effect is to use the rope of getting core to hang embolism.
When (4) using this embolism, connect the sebific duct of inflation usefulness earlier, with rope embolism is transferred in the hole then, be sitting on the interior step of drill bit, utilize the nitrogen cylinder air feed, embolism is expanded, sealing drilling rod and part are holed.
(5) after test was finished, release proposed embolism, continues to creep into.
The utility model compared with prior art has following useful technique effect:
The utility model is through test and the practical application in the exploration engineering of " the ancient virtuous key water control project in the Yellow River ", the sufficient proof embolism can be transferred to the desired position very smoothly, the air bag expansion rate is big, radially can expand into 100mm from 50mm, can effectively distinguish shutoff drilling tool inwall and boring. Can avoid contacting with the drill bit blade when embolism expands, eliminate the destruction of drill bit blade to the embolism capsule. Can restore to the original state fast after the embolism release, be easy to lift to the face of land. The long service life of embolism, low price is fit to the water pressure test in borehole requirement that the employing wire line coring creeps into very much, is the innovation on the exploring equipment.
