Description
Technical field
The present invention relates to a kind of method adopting water block device (water blockoff plug) to carry out packer permeability test, a kind of method adopting sliding hydraulic plug water block device to carry out packer permeability test specifically.
Background technology
In water conservancy and hydropower prospecting process, carrying out packer permeability test in boring is the conventional means understanding permeability of rock massf, needs to use water block device (water blockoff plug) that the packer permeability test section in boring is carried out water blockoff (water proof) during test.
Prior art is when carrying out water blockoff to the packer permeability test section in boring, need operating personnel after probing and having cleaned hole wall, first drilling rod, drilling tool are mentioned, then existing water block device (as roof pressing type expands plug, suspended hydraulic plug) is fixed on drilling rod, then transferring in boring by water blockoff equipment (including water block device and drilling rod) again, rearmost can carry out packer permeability test. Simultaneously, water block device owing to being positioned at fragmented rock body place easily occurs cannot the situation of effective water blockoff (water proof), therefore existing water block device is when fragmented rock body place carries out water blockoff, it is necessary to water blockoff equipment is repeatedly mentioned and transfers by operating personnel, to determine the final water blockoff position of water block device.
In sum, prior art is when adopting existing water block device that the packer permeability test section in boring is carried out water blockoff, and its technical scheme is more complicated, and operating personnel's labor intensity is relatively big, and work efficiency is relatively low, and the activity duration is longer, it is therefore necessary to improve.
Summary of the invention
The invention aims to overcome the weak point of background technology, and provide a kind of method adopting sliding hydraulic plug water block device to carry out packer permeability test, more convenient to operate, the labor intensity of operating personnel is less, and work efficiency is higher, and the activity duration is shorter.
To achieve these goals, the technical scheme is that the method adopting sliding hydraulic plug water block device to carry out packer permeability test, it is characterized in that: it comprises the technical steps that, step 1: after probing terminates, clean the hole wall of boring, and ready compressed water generation apparatus, pressue device and sliding hydraulic plug water block device are placed near drilling rod;Step 2: make the outfan of pressue device and the upper pressurization orifice of sliding hydraulic plug water block device, and make the end of suspension rope be connected with the upper lift ring of sliding hydraulic plug water block device; Step 3: sliding hydraulic plug water block device is enclosed within drilling rod, and make the outfan of compressed water generation apparatus be connected with the vacant end of drilling rod; Step 4: make sliding hydraulic plug water block device slide along drilling rod to bore inner by suspension rope, until packer permeability test section place place sliding hydraulic plug water block device slided in boring, meanwhile, by sliding hydraulic plug water block device, described packer permeability test section is carried out first heavily to block; Step 5: pressue device is pressurizeed to inside sliding hydraulic plug water block device by compression tube, the interior expanded film making sliding hydraulic plug water block device expands, until interior expanded film holds drilling rod tightly, and make the outer expanded film of sliding hydraulic plug water block device expand, until outer expanded film blocks the hole wall of boring, now realize heavily blocking the second of described packer permeability test section; Step 6: hold drilling rod tightly at interior expanded film, and after outer expanded film blocks the hole wall of boring, staff can carry out packer permeability test by compressed water generation apparatus.
In technique scheme, in step 4, when packer permeability test section is positioned at boring lower end, sliding hydraulic plug water block device is positioned over the top of packer permeability test section; When being positioned at boring upper end or middle part when packer permeability test section, a sliding hydraulic plug water block device is respectively placed on the top of packer permeability test section and bottom, the first water block device that two sliding hydraulic plug water block devices are respectively above, with the second water block device being positioned below, the lower lift ring of the first water block device and the upper lift ring of the second water block device is made to connect by suspension rope, by the upper pressurization orifice of the lower pressurization interface of compression tube the first water block device and the second water block device.
Compared with prior art, it has the advantages that the present invention
1., after packer permeability test completes, owing to outer expanded film can return to state when not expanding because the pressure in boring plug reduces, therefore the water block device of the present invention will not be stuck in boring, and water block device can be taken out by operating personnel very easily in boring; Simultaneously as the present invention adopts has double plugging measure, therefore the water plugging effect of the present invention is better.
2. owing to water block device of the present invention is the sliding hydraulic plug water block device that can be enclosed within drilling rod and can slide on drilling rod, therefore when the packer permeability test section in boring is blocked, the present invention has only to be enclosed within drilling rod water block device, and water block device is interior along drilling steel slip to boring. Compared with prior art, the mode that the present invention not only installs water block device is simpler, and eliminate that prior art have to carry out when installing water block device mention rig and put into the operation of rig.
3. when the water block device (sliding hydraulic plug water block device) of the present invention is positioned at fragmented rock body place, operating personnel has only to the water block device making the present invention and slides on drilling rod, and adjust the position of water block device, it is not necessary to again drilling rod is mentioned in the lump together with water block device. Therefore, when the present invention carries out water blockoff test at fragmented rock body place, it is more convenient to operate, and the labor intensity of operating personnel is less, and work efficiency is higher, and the activity duration is shorter.
