Description
Technical field
The present invention relates to the engineering investigation method, particularly the pressure of the drill water test automatic test approach is not carried in a kind of wire line coring boring.
Background technology
In the engineering investigation work, it is a kind of very efficiently drilling technology that wire line coring creeps into.In drilling process, after core is full of core barrel, need not carry wammel, but take drilling rod as passage, by means of Special fishing tools such as ropes, the core that is stored in the drilling process in the interior core barrel be risen to outside the hole.Because this method do not need all drilling rods are risen to outside the hole, thus greatly reduced the time of drilling, also decrease labour intensity.This technology is at mineral products, and the industries such as coal, oil have been widely used, and has obtained significant effect.
But, the Hydraulic and Hydro-Power Engineering exploration is because the singularity of himself, the wire line coring drilling technology is not well promoted, 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 commonly used 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 injection conduit again in the hole section, then tests; 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 be with wire line coring this efficiently creep into technology transplant and be applied to the water conservancy and hydropower exploration engineering, can obtain high-precision test figure simultaneously.
Summary of the invention
For 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 Measurement 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, holed at 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 earth's surface, then continue drilling test.
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 together, can significantly improve exploration quality and the efficient of water conservancy and hydropower medium-length hole, effectively reduce labour intensity.
