Abstract
The utility model discloses a separate six-arm caliper microsphere and microelectrode combined logging instrument, which comprises a logging instrument body, an arm tie, a pole plate test arm, a bearing rod and etc. It is characterized in that the lantern test arm is installed on the logging instrument body over the pole plate test arm, a spring sleeve and a spring pushing rod are connected in the logging instrument body and on the top of the arm tie sequentially, a main spring is fixed in the spring sleeve, the lower end of the spring is hinged with the end of the pole plate test arm through the spring guiding rod and the tie rod, the spring tie rod is connected with the caliper leg spring sleeve hinged on the spring push rod. The utility model can measure three parameters simultaneously while testing oil well, which have such advantages as convenient application and high accuracy in measurement.
Description
One, technical field: the utility model relates to a kind of downhole testing instrument, particularly a kind of separate type six arm microballoon microelectrode hole diameter combination logging tools.
Two, background technology: at present, this three technology index of micrometer ball, microelectrode and hole diameter in the oil reservoir logging process will adopt the different measuring instrument to test separately and finish, and the testing time is long, and can not survey horizontal well, existing can not repeat logging, the shortcoming of down-hole accident easily takes place.
Three, summary of the invention: the purpose of this utility model just is to provide a kind of ball of micrometer simultaneously, microelectrode and hole diameter three technology index, and can survey instrument---the separate type six arm microballoon microelectrode hole diameter combination logging tools of horizontal well and repeat logging.Technical solution of the present utility model is: described combination logging tool mainly comprises logging instrument body, arm-tie, pole plate test arm, cramp bar, piston rod and swing pole plate, microballoon pole plate etc., and the logging instrument body above the pole plate test arm is provided with the lantern body formula test arm that is made of hole diameter leg, the secondary leg of hole diameter and pogo barrel; In the logging instrument body, the top of arm-tie is connected with spring housing, the other end of spring housing is connected with spring push-rod, be fixed with main spring in spring housing, the lower end of main spring is connected with pull bar by spring guide, and pull bar is hinged with the end of two pole plate test arm respectively; Be connected with the spring pull bar on the hole diameter leg, the spring pull bar is connected with hole diameter leg pogo barrel, and the other end of hole diameter leg pogo barrel is hinged on the spring push-rod, is respectively arranged with auxiliary spring and hole diameter leg spring in pogo barrel and hole diameter leg pogo barrel; Be connected with the test arm pull bar on the pole plate test arm, the test arm pull bar is connected with the test arm pogo barrel, and the other end of test arm pogo barrel is hinged with the spring base that is fixed on the arm-tie, is provided with the test arm spring in the test arm pogo barrel.The utility model modern design, rational in infrastructure, can once measure the three technology parameter index, be applicable to horizontal well, inclined shaft, straight well well logging, the energy repeat logging has been avoided the generation of down-hole accident, improve the well logging timeliness greatly, had easy to use, stable performance, advantage that certainty of measurement is high.
Four, description of drawings: Fig. 1 is the utility model embodiment master TV structure cross-sectional schematic.
Five, the specific embodiment: described combination logging tool mainly comprises logging instrument body 1, arm-tie 2, pole plate test arm 3, cramp bar 4, piston rod 22 and swing pole plate 5, microballoon pole plate 6 etc., be set with piston rod spring 23 on piston rod 22, the logging instrument body 1 above the pole plate test arm 3 is provided with the lantern body formula test arm that is made of hole diameter leg 7, the secondary leg 8 of hole diameter and pogo barrel 9; In logging instrument body 1, the top of arm-tie 2 is connected with spring housing 10, the other end of spring housing 10 is connected with spring push-rod 11, in spring housing 10, be fixed with main spring 12, the lower end of main spring 12 is connected with pull bar 14 by spring guide 13, and pull bar 14 is hinged with the end of two pole plate test arm 3 respectively; On hole diameter leg 7, be connected with spring pull bar 15, spring pull bar 15 is connected with hole diameter leg pogo barrel 16, the other end of hole diameter leg pogo barrel 16 is hinged on the spring push-rod 11, is respectively arranged with auxiliary spring 17 and hole diameter leg spring 18 in pogo barrel 9 and hole diameter leg pogo barrel 16.On pole plate test arm 3, be connected with test arm pull bar 19, test arm pull bar 19 is connected with test arm pogo barrel 20, the other end of test arm pogo barrel 20 is hinged with the spring base 21 that is fixed on the arm-tie 2, is provided with test arm spring 24 in test arm pogo barrel 20.
Operating principle of the present utility model is: arm-tie 2 fuses with spring housing 10 and spring push-rod 11, forms unified push rod, does pumping under the forward and reverse effect of motor.
When arm-tie 2 during to left movement, hole diameter leg pogo barrel 16 drives 15 motions of spring pull bars, pulling hole diameter leg 7 closures, and the auxiliary spring 17 in the secondary leg 8 compression pogo barrels 9 of hole diameter is realized lantern body formula test arm closure; Meanwhile, main spring 12 is by spring guide 13 and pull bar 14 pulling pole plate test arm 3 closures, and test arm pogo barrel 20 drives 19 motions of test arm pull bar and also spurs pole plate test arm 3 closures, finally realizes pole plate test arm closure.
When arm-tie 2 moved right, under the reaction force acts of hole diameter leg spring 18, auxiliary spring 17 and piston rod spring 23, lantern body formula test arm was opened and is duty; Under the reaction of test arm spring 24 and main spring 12, pole plate test arm 3 is opened, and is close to the borehole wall, is duty, realizes that the mensuration of technical indicators such as microelectrode, microballoon and hole diameter is finished.
