Be provided with sealing device in intermediate, to be that the seal of truncated cone-shaped and reverse frustoconic is nested by cross section constitute sealing device, is fixed with thread bush in the outside, end of seal; On leading screw, be fixed with the stroke contact.
The utility model is simple in structure, and is easy to use, and test data is accurate, can test 450 with interior big or middle hole diameter, especially can test the small-well-diameter of 118; The utility model can upper and lower reciprocal retest layering hole diameter and data such as little resistance, test to and testing expense all can reduce about 50%, can avoid simultaneously the down-hole to meet the generation of accidents such as card, help safety in production, the utlity model has stable and reliable for performance, characteristics such as maintenance easy accessibility are a kind of desirable loggers that improves the well logging project and improve the well logging economic benefit.
Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.
Fig. 1 is a main TV structure cross-sectional schematic of the present utility model;
Fig. 2 is the plan structure enlarged diagram of mechanism for testing of the present utility model;
Fig. 3 is a sealing device structure enlarged diagram of the present utility model.
With reference to accompanying drawing, the utility model is mainly by joint 1, motor bin 4, intermediate 9, mechanism for testing 10, spring case 12, balance bunker 13 and protective sleeve 16 are formed by connecting threadably in turn, mechanism for testing 10 is mainly by pole plate 18, armed lever 19, pole 20 and pull bar 25 are formed, when joint 1 is used to log well and other instruments, equipment interconnection, in motor bin 4, be provided with attaching plug 2 and motor 3, motor 3 is connected with leading screw 6 by adapter sleeve 5, the other end of leading screw 6 is connected with screw 7 threadably, screw 7 is connected as a single entity with drive rod 8, the other end at drive rod 8 is provided with extension spring seat 22 and splicing sleeve 26, be set with extension spring 27 outside the drive rod 8 of between, splicing sleeve 26 links into an integrated entity with the intermediate 9 of outside, drive rod 8 can be gone up therein, following motion, be hinged with pull bar 25 on the splicing sleeve 26, on intermediate 9, be fixed with armed lever 19, be provided with the pole plate 18 of three contacts of tool at armed lever 19 and 25 on pull bar, on armed lever 19, be fixed with pole 20, the other end of pole 20 is fixed on the extension spring seat 22, and pole 20 is provided with pole extension spring 21; Be provided with potentiometer 28 and push rod 23 in spring case 12, be set with stage clip 24 outside the push rod 23, an end of push rod 23 contacts with potentiometer 28, and the other end contacts with the top of armed lever 19.
In intermediate 9, the outer setting of drive rod 8 has sealing device 11, this device is seal 29 nested the forming of truncated cone-shaped and reverse frustoconic by cross section, and the material of seal 29 is a polytetrafluoroethylene (PTFE), has been fixed with the thread bush 30 of fixation in the outside, end of seal 29.On leading screw 6, be fixed with stroke contact 17, in balance bunker 13, be provided with balance pipe 14 that keeps the internal and external pressure balance effect and the plug 15 that is used for output signal.
The utility model is except that logging operation, and mechanism for testing all is in closure state.The process of closed mechanism for testing is as follows: starter motor 3, motor 3 drives leading screw 6 by adapter sleeve 5 and rotates, drive screw 7 and drive rod 8 simultaneously vertically towards deviating from the motor drive direction motion, extension spring 27 this moment, extension spring seat 22, pole extension spring 21 and pull bar 25 etc. move vertically with drive rod 8, the active force that overcomes compression spring 24 heads into push rod 23 in the spring case 12, simultaneously armed lever 19 is pushed receipts and come on the intermediate 9, bump 17 outages of stroke contact this moment.Because extension spring 27 and pole extension spring 21 are not done work, and 3 in motor promotes compression spring 24, and motor load is light, electric current is little when closed.
When opening mechanism for testing, motor 3 drives leading screws 6 by adapter sleeve 5 and rotates, and drives screw 7 simultaneously and drive rod 8 is done axially-movable to motor drive direction together, and extension spring 27 this moment, extension spring seat 22, pole extension spring 21 and pull bar 25 etc. are with drive rod 8 motions; Compression spring 24 resets and by push rod 23 armed lever 19 jack-up is flared to maximum, bumps 17 outages of stroke contact.Because extension spring 27 and pole extension spring 21 are not done work, and armed lever is opened by compression spring 24 jack-up, motor load is also little when closed when opening.
During well logging, to make up instrument puts to well build-in test position with cable, by transmission mechanism mechanism for testing is opened, compressing spring this moment opens by push rod drive armed lever, make pole plate 18 and armed lever head 31 be close to the borehole wall, variation along with cable lifting and hole diameter, under the effect of pole spring, extension spring and compression spring, make pole plate and armed lever head open, shrink with the borehole wall automatically, promote the motion of potentiometer slide bar by push rod, the back is treated to the ground computer can obtain hole diameter and little resistance curve with this signal feedback.
