Abstract
The invention provides a 3.5-millimeter load-bearing exploration cable logging device. A crawler-belt traction device is arranged on the middle upper portion of a traditional anti-spray tube. Power of the crawler-belt traction device is exerted by a hand wheel through belt pulleys to drive a belt. Tension of the chain crawler-belt traction device is achieved through an upper eccentric bushing, a lower eccentric bushing and an eccentric bushing which is arranged opposite to and corresponding to the upper eccentric bushing and the lower eccentric bushing. The 3.5-millimeter load-bearing exploration cable logging device overcomes the defects of an existing load-bearing exploration cable logging device, enables the cable to be descended into a well smoothly, saves working hours, and eliminates pollution of well liquid to the environment.
Description
Technical field
The present invention is the oil field cable unit, is specially adapted to 3.5 millimeters millimeter charge bearing detecting cable downhole devices.
Background technology
The bearing detection millimeter charge bearing detecting cable downhole device of existing conventional structure, usually inner at lubricator, hang in the instrument lower end and add that weight linear meter realizes.Because the common 2 meters left and right of lubricator, limited by pipe aperture, that increases the weight of to do is very thick, therefore the instrument counterweight can not meet instrument and the cable needs of going into the well, therefore in order conveniently to go into the well, it is very tight that cable seal plug below pulley just can not be adjusted ground, to such an extent as to cause leaked liquid in well, causes ground pollution.That is to say, the sealing of cable seal plug is too tight, and liquid has not been revealed in well, and the cable seal plug is larger to the resistance that cable is subject to, and instrument and counterweight are just drawn motionless cable, under cable not well.Otherwise leakage has too large, contaminated environment.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art and a kind of 3.5 millimeters charge bearing detecting cable downhole devices are provided.
The technical solution adopted in the present invention is: 3.5 millimeters charge bearing detecting cable downhole devices, and inner at lubricator, to hang in the instrument lower end and add weight linear meter, ball valve is the water injection well in oil fields head valve, interface thread is end interface on the water injection well in oil fields head valve.Crawler has been designed at upper middle part at traditional lubricator, and the power of crawler drives belt by handwheel by belt pulley and applies.
The top eccentric bushing of the tensioning of chain crawler and lower eccentric bushing, and eccentric bushing corresponding to upper eccentric bushing and lower eccentric bushing opposite consists of.
Device is placed in the cavity of circular tube structure.
Compared with prior art, advantage of the present invention is: overcome the defective of existing bearing detection millimeter charge bearing detecting cable downhole device, cable is gone into the well smoothly, save man-hour, eliminate well liquid pollution on the environment.

The specific embodiment
Describe embodiments of the invention in detail below in conjunction with accompanying drawing.
3.5 millimeter charge bearing detecting cable downhole device is inner at lubricator, hangs in the instrument lower end to add weight linear meter, ball valve 6 is the water injection well in oil fields head valve, and interface thread 7 is end interface on the water injection well in oil fields head valve.
Embodiment 1:
As shown in Figure 1 and Figure 2: crawler 4 has been designed at the upper middle part at traditional lubricator 16, for the ease of making, this device is placed in the cavity of circular tube structure 3.The power of crawler 4 is carried on belt pulley 13 by belt pulley 14, belt 15 by handwheel 9.
In order to prevent that crawler 4 and cable from skidding, the tensioning of crawler belt is top eccentric bushing 11, with lower eccentric bushing 12, and eccentric bushing corresponding to upper eccentric bushing 11 and lower eccentric bushing 12 opposites consists of, like this in the situation that chucking power is inadequate, can adjust eccentric bushing 11, with lower eccentric bushing 12, and upper eccentric bushing 11 and eccentric bushing corresponding to lower eccentric bushing 12 opposites change in 4 pairs of cable 19 chucking powers of crawler.
Embodiment 2:
As shown in Figure 3, Figure 4: crawler 4 has been designed at the upper middle part at traditional lubricator 16, for the ease of making, this device is placed in the cavity of circular tube structure 3.In order to prevent that crawler 4 and cable from skidding, the tensioning of crawler belt is top eccentric bushing 11, with lower eccentric bushing 12, and eccentric bushing corresponding to upper eccentric bushing 11 and lower eccentric bushing 12 opposites consists of, like this in the situation that chucking power is inadequate, can adjust eccentric bushing 11, with lower eccentric bushing 12, and upper eccentric bushing 11 and eccentric bushing corresponding to lower eccentric bushing 12 opposites change and add the power of holding.
Operating physical force is added to above crawler 4 by gear 10 gears 8 by handwheel 9, gives downward pulling force of cable, makes cable in the situation that be subject to the larger resistance of cable blowout control plug 2 and can go into the well smoothly in the same old way.
