Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of well logging detector device of the utility model, its main body 17 is the cylinder body structure, its underpart is installed balance weight body 15, signal receiving device 14 successively.The end of balance weight body 15 is a streamlined, can increase overall weight by changing its length, and effect all is to be convenient to the well logging detector device main body and sinks to the well logging bottom in slurry environment.Signal receiving device 14 inner sealings have three to be the wave detector that cartesian coordinate system distributes, form three-component seismometer, be used for from multi-faceted reception seismic signal, and be connected with the seismic instrument on ground by the inwall of a signal-transmitting cable 1 along main body 17 and metal hose 3.
Pushing device, pulling apparatus and metal hose 3 parts are installed in the utility model main body 17.Pushing device adopts mechanical push arm formula.Pushing device mainly comprise driver element, support arm 13 and four-bar mechanism.Driver element can be a cylinder, and hydraulic cylinder or a motor add screw mechanism, can also be the steel wire ropes.
As driver element, its terminal stationary shaft 16 that passes through links to each other with main body 17 the utility model, is installed in the main body, which is provided with two air intake openings with double acting circular cylinder 7.Two enhancing tracheae 5 one ends link to each other with double acting circular cylinder 7 air intake openings respectively, and the other end hand control valve other with being positioned over well head links to each other.
Four-bar mechanism includes push rod 8, support arm fixed block 9, support arm push rod 11, gyration block 12, push rod 8 one ends and piston rod are hinged, the other end and gyration block 12 and support arm push rod 11 are hinged, an end and support arm fixed block 9 that support arm push rod 11 stretches out main body are hinged, support arm fixed block 9 other ends are hinged in main body by bearing pin 18, gyration block 12 other ends also are hinged in main body by another bearing pin 18, and its end is the circular saw dentalation, help making the small embossment position chucking of the main body and the borehole wall.Support arm 13 is fixed on the support arm fixed block 9, and the one end is connected with the support arm fixed block 9 of four-bar mechanism with fixed pin shaft 10, and the other end is designed to the brave pawl structure of outer folding.Tiger pawl structure can penetrate in the borehole wall more easily, increases the chucking and the coupling of the main body and the borehole wall.The outer wall section of the utility model signal receiving device 14 is provided with a concave plane, and support arm 13 can be adjacent at this face just, makes its brave pawl structure not interfere with main body external cylindrical surface object outward.
As operating personnel during by the 7 back air intake openings inflations of hand control valve pair and double acting circular cylinder, gases at high pressure are finished by enhancing tracheae 5 driving double acting circular cylinders 7 and are stretched out the piston rod action, stretching out and driving push rod 8 of piston rod moved, four-bar mechanism is rotated accordingly, thereby support arm 13 is released and held out against on the borehole wall.After support arm opens in well logging, just can bleed off pulling force to wire rope 2, because the action of gravity of main body, the brave pawl of support arm 13 just penetrates in the borehole wall dearly, has more increased the coupling effect of the main body and the borehole wall.
When the situation that the inflation to cylinder 7 nose air intakes is pressurizeed, the front side gases at high pressure are pushed piston rod to rear side in the cylinder, thereby guaranteed that support arm 13 also is adjacent on the outerplanar of signal receiving device 14 firmly by the open configuration withdrawal, the result who does has like this avoided support arm 13 to open outside easily in main body is gone into the well process to run into borehole wall protruding point, and the situation that main body is blocked.
The concrete course of work is: at first regulate hand control valve and pressurising to 2 atmospheric pressure, after support arm 13 is tightened up, operating personnel only need lift wire rope 2 and main body is progressively put into well logging from well head, when main body arrives minimum test point, stop to transfer main body, can use pair enhancing tracheae inflation that is connected with cylinder 7 back air intake openings of micro air pump or gas cylinder, air pressure in pipe acquires a certain degree, piston rod promptly drives parallel motion support arm 13 is released, the operating personnel that carry wire rope 2 this moment can loosen earlier exploratoryly and on mention wire rope 2, can confirm whether support arm 13 has opened and hold out against on the borehole wall, and can feel to obtain the intensity of support arm 13 push-tights, if on lift force rate and can loosen pulling force when big fully wire rope 2, because the effect of main body gravity, comparatively sharp-pointed brave pawl structure will penetrate dearly in the earth of the borehole wall and with main body and withstand on the borehole wall tightly.
Because can there be certain deformability in gas, when test point below instrument test is intact, do not need the gases at high pressure that strengthen in the tracheae 5 are discharged, the operating personnel that are positioned at well head only need draw wire rope 2 just main body can be mentioned a last test point from next test point with strength, and the brave pawl of support arm 13 closely contacts with the borehole wall all the time, up to wire rope 2 is broadcasted pulling force, the brave pawl of support arm 13 can penetrate in the borehole wall once more owing to the action of gravity of main body again.
