Description
Technical field
The invention belongs to borehole survey correlative technology fields, and in particular to a kind of Novel centralizer of borehole logging.
Background technique
Drilling refers to the operation processed and portalled on solid material with drill bit, teaches the drillman in investigation and prospecting here
Make, and the auxiliary tool that needs of drilling and part emergency measure method, in geological work, usually with drilling machine to underground
Drilling at diameter it is smaller and with certain depth wellhole be known as drill, borehole survey is the important of Geophysical Logging
Component part plays extremely important work in terms of drilling quality detection, drilling orientation, mineral resources assessment, shaft building
With especially drillhole inclination survey technical application makes drillhole inclination survey technology to engineering construction and construction engineering test aspect in recent years
Research and application are paid more and more attention, and boring positioning measurement (hole position survey) will be drilled by design requirement
Position, which is surveyed, to be set to (preliminary survey stage) on the spot and corrects stake according to repetition measurement behind smooth drilling machine airport, when restoring to determine smooth airport
The bore position (repetition measurement stage) being destroyed and measurement drill center (sealing of hole mark center or casing top surface after probing
Center) plane coordinates and elevation (surveying the stage surely) etc. measurement work, and centralizer be belong to cementing tool, it is simple to manufacture,
Structure is beautiful, and firm and durable, uprighting force is big, overcomes the deficiency that desoldering easily occurs for former welded type centralizer, is that one kind can guarantee
The centralizer of well drilling and cementing quality, centralizer can be divided into two major classes, elastic centralizer and rigid centralizer (soft righting according to pattern
Device and hard centralizer), hard centralizer, maximum drawback be easy to cause probe card hole (being stuck in hole) and scrap, and its
The ability for adapting to different pore size is weaker, and volume is larger, and soft centralizer is essentially laminated structure, and really centralizer is with hole wall
Point contact, though this structure does not easily cause card hole phenomenon, and it is actual the reason of weak material and point contact with hole wall
Centering effect is simultaneously bad, and especially hole has its own strength of inclination that can not can not restore shape itself, keeps probe placed in the middle, and every
Kind drilling, every kind of probe must all match different centralizers, and versatility is not all right, and the centralizer in field at present, can not solve
Probe certainly in the irregular situation of hole wall is placed in the middle, using any of the above centralizer, all be easy to cause probe in drilling (well
In) shake.
Existing borehole logging is had the following problems with centralizer technology: more used in existing drilling (in well) measurement
Number be hard centralizer and soft centralizer, hard centralizer, maximum drawback be easy to cause probe card hole (being stuck in hole) and
It scraps, and its ability for adapting to different pore size is weaker, volume is larger, and soft centralizer is essentially laminated structure, really helps
Positive device and hole wall are point contacts, though this structure does not easily cause card hole phenomenon, weak material and with the point contact of hole wall
Reason, actual centering effect is simultaneously bad, and especially hole has its own strength of inclination that can not can not restore shape itself, makes to visit
Head is placed in the middle, and every kind of drilling, every kind of probe must all match different centralizers, versatility is not all right, and field is helped at present
Positive device, the probe that can not solve in the irregular situation of hole wall is placed in the middle, using any of the above centralizer, all be easy to cause
It pops one's head in the shake of drilling (in well).

The open-work 2 on probe fixation hole 8 and bottom fixed board 1 on top fixing plate 7 is circle, and the circumferential area of open-work 2 is big
In the circumferential area of probe fixation hole 8, in this way when needing to install probe on centralizer, visited because the area of open-work 2 is greater than
The area of head fixation hole 8, so that probe smoothly can pass through open-work 2 during installation and be installed to probe fixation hole
8 inside.
The working principle of the invention and process for using: after the present invention installs, when in use, it is necessary first to which three are helped
Positive brush 5 assembles, and is specially installed on brush board 13 the fixinig plate 11 with hairbrush 10 is fixed by snap, then assembling
Good righting brush 5 connects by the way that the left intermediate plate 6 and right clamping piece 3 that connect on brush board 13 and bottom fixed board 1 and top fixing plate 7 are fixed
It connects, particularly brush board 13 is inserted into the centre of every group of left intermediate plate 6 and right clamping piece 3, then by three fixing screws 4 brush
Plate 13 is connected and fixed with left intermediate plate 6 and right clamping piece 3, this makes it possible to quick and firmly righting brush 5 is installed, so
Other two righting brush 5 is installed on other two groups left intermediate plates 6 and right clamping piece 3 in the same way afterwards, and righting brush 5 is adopted
Size needs are determined according to the size in aperture, then then need probe to be connected on the novel centralizer, first
Open-work 2 of the probe on bottom fixed board 1 is then passed through the probe fixation hole 8 on top fixing plate 7, and top fixing plate
The quickly position to two spies quickly is visited in above one of probe in the position that probe fixation hole 8 on 7 is placed, in addition more special work
The needs of condition are also possible to adjust, and then the centralizer for being connected to probe, which is extend into inspecting hole, can carry out using and this is helped
The length of hairbrush 10 on the righting brush 5 of positive device determines the pore diameter range that the centralizer adapts to, and the height of hairbrush 10 determines
The length contacted with hole wall, to solve the adaptability problem of pore size, also solve soft centralizer and hole wall
Point contact so which is connected probe be provided with good centering effect, and hairbrush 10 length it is longer with
Hole wall contacts, it is equivalent to the smooth degree for being mathematically weighted and averaged hole wall, Gu it can preferably adapt to hole wall variation, and protects
Card probe is not shaken, that is, realizes the detection of rough hole wall structure, particularly prefabricated pile, and because righting brush 5 is solid
Surely be connected to top fixing plate 7 and bottom fixed board 1 on inward wall, and only need the probe on top fixing plate 7 solid
Determine the versatility that hole 8 cooperates different probes that series probe can be realized, and the probe of oneself of currently all producer has
One standard has oneself a common interface, we then can at least guarantee one at fixation hole 8 of popping one's head in using this interface
