Abstract
The present invention relates to an oil-field logging tool-obstruction-meeting guide centralizer. The described centralizer includes at least a group of movable slide blocks, three groups of upper and lower centralizing arms and reset spring, the lower centralizing arms are movably connected with upper centralizing arms by means of hinge, and respectively fixedly connected with centralizer self-body by means of fixing hinge.
Description
One, technical field: the present invention relates to a kind of oil reservoir logging instrument, particularly a kind of interference happening guiding centralising device that utilizes the logging operation that the rigidity propulsion method carries out.
Two, background technology: along with deepening continuously of oil field development, particularly used since the insert pump oil recovery, oil pumping rod centering device is own through becoming the indispensable instrument that recovers the oil in the oil field.And most instruments are often irregular because of the borehole wall in the domestic and international existing oil pumping rod centering device well logging process, have situation such as projection depression etc. to cause downhole instrument to be hampered, and gently then can't normally finish logging tasks, and are heavy then may damage logger by pressure.
Three, summary of the invention: purpose of the present invention is exactly the above-mentioned defective that exists at prior art, provides a kind of and can make the interference happening guiding centralising device of logger by the tight point smoothly.
Its technical scheme is: comprise centralizer, wherein, at the front end of centralizer elastic guide glue awl is set, described centralizer comprises having one group of movable slider (11) at least, three groups of upper and lower righting arms (7,10) and back-moving spring (8).
Better technical scheme is that described righting arm (10) down and last righting arm (7) flexibly connect by hinge (9), and fixedlys connected with centralizer body respectively by fixed hinge (6).
Effect of the present invention is: the present invention can be when the instrument front end be hampered, automatically increase the centralizer size, change the position of instrument front end in well, thereby separate resistance smoothly, separating again can be under the effect of spring after the resistance, automatically recover reset condition, thereby improve well logging timeliness and success rate, also guaranteed the safety of logger to a certain extent.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the invention will be further described:
Guide head is installed in guider foremost by fairlead 14, link with movable slider 11, movable slider 11 is in connecting rod 3 activities of the effect lower edge of resistance, compression spring 8 promotes righting arm 10 down, last righting arm 7, under the effect of the effect of hinge 9 and fixed hinge 6, righting arm 7,10 struts about making, and after removing when being hampered, spring 8 promotes movable sliders 11 and drives upward 7 times righting arms of righting arm, 10 recovery original diameters.
Can adjust initial diameter by adjusting gag lever post 12.Top connection 1 links to each other with the top logger by threaded collar 15, and " O " RunddichtringO 2,13 plays the effect of sealing anti-rotation, and stop pin 5 prevents from owing to the effect of righting arm connecting rod 3 and top connection 1 to be broken away from.
Claims (2)
1, a kind of interference happening guiding centralising device comprises centralizer, it is characterized in that: the front end at centralizer is provided with elastic guide glue awl, and described centralizer comprises having one group of movable slider (11) at least, three groups of upper and lower righting arms (7,10) and back-moving spring (8).
2, interference happening guiding centralising device according to claim 1 is characterized in that: described righting arm (10) down and last righting arm (7) flexibly connect by hinge (9), and fixedly connected with centralizer body respectively by fixed hinge (6).
