Description

The pressure of the drill water test automatic test approach is not carried in wire line coring boring
Technical field
The present invention relates to the engineering investigation method, the pressure of the drill water test automatic test approach is not carried in particularly a kind of wire line coring boring.
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 carry wammel, but be passage with the drilling rod, by means of special-purpose fishing tools such as ropes, the core in the core barrel in being stored in the drilling process is risen to outside the hole.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 because the singularity of himself, the wire line coring drilling technology does not obtain excellent popularization, water conservancy and hydropower exploration need be carried out various physico-mechanical propertieses tests and hydrogeological test usually, and wherein packer permeability test (5m is a test section) is that the in-situ testing method used always is to obtain hydrogeologic data.Usually water-pressurizing test method is to creep into end and drilling rod after whole the proposition, is lowered to setting-out embolism and water filling conduit again in the hole section, tests then; This test routine is difficult to the advantage that the performance wire line coring creeps into, this experimental technique can not accurately reflect the pressure in the setting-out examination section simultaneously, if can be in conjunction with the characteristics of water conservancy and hydropower exploration, the packer permeability test automatic test technology of wammel is not carried in design, just can well can obtain high-precision test figure simultaneously with this efficient drilling technology graft application of wire line coring to the water conservancy and hydropower exploration engineering.
Summary of the invention
At above-mentioned situation, for overcoming the defective of prior art, the present invention's purpose just provides a kind of wire line coring boring and does not carry the pressure of the drill water test automatic test approach, can effectively solve the pressure in the accurate mensuration packer permeability test section, give full play to the advantage problem that wire line coring is not proposed brill and the automatic test of packer permeability test.
The technical scheme that the present invention solves is, packer permeability test embolism and port seal at first are set, hole on rock by drilling machine again, when boring reaches test length, take out core, to carry on the hollow drill in the boring, and then hang the packer permeability test embolism with the inflation sebific duct, communicate in inflation sebific duct and the packer permeability test embolism, and the packer permeability test embolism packed in the hollow drill, the seal capsule on packer permeability test embolism top places in the hollow drill, the seal capsule of packer permeability test embolism bottom stretches out outside the drill bit of hollow drill bottom, place in the boring, then, to inflate sebific duct and nitrogen cylinder connects, upper-lower seal capsule inflation to embolism, closed hollow drilling rod and boring, afterwards, the pressure transducer of test section and the flow sensor of boring outside are connect on the packer permeability test comprehensive tester through cable, and by the port seal hermetically-sealed cable, then by water pump by port seal and hollow drill internal channel to the boring section setting-out that separates, and according to packer permeability test rules image data, after the data acquisition, the embolism release, carry to the face of land, continue drilling test then.
The present invention is simple to operate, practical, can fully play wire line coring and creep into the advantage of not carrying brill, with wire line coring and packer permeability test and automatically test well be fused to together, can significantly improve the exploration quality and the efficient of water conservancy and hydropower medium-length hole, effectively reduce labour intensity.
