Description

Technical field:

[0001] The present invention relates to the technical field of petroleum exploration and development, and in particular to a remote control device for the calibration of a density logging instrument. Background technology:

[0002] When calibrating the lithologic density instrument, the instrument probe, radioactive source, scale block, and scale piece are required to be parallel in the longitudinal direction and coplanar in the transverse direction, and to be in close contact during counting and measurement. The instrument design and manufacturing manufacturer recommends that the instrument be placed vertically for calibration. However, due to the conditions of the calibration workshop and the difficulty in developing and arranging calibration auxiliary equipment, horizontal placement of the scale is also allowed by the instrument manufacturer. Therefore, in daily use, the horizontal placement method is adopted.

[0003] Lithologic density instruments are radioactive logging instruments. Normal operation requires the installation of a Cs137 gamma source. Calibration requires the installation of the same radioactive source used for logging to ensure measurement accuracy. The calibration process requires repeated pressure application and depressurization of the calibration device, as well as the installation and removal of calibration reference objects. The instrument also requires monthly calibration, exposing operators to high doses of ionizing radiation for extended periods, posing a serious threat and hazard to their health. Manual operation, improper calibration device design, and a loose fit between the radioactive source and the object being measured can all lead to deviations in measurement results. Furthermore, for instruments between 3 and 5 meters in length, inconsistent front and rear bracket heights or forces can cause the instrument to tilt, resulting in a loose fit between the instrument and the object being measured, further contributing to deviations in measurement results. Summary of the invention:

[0050] The 6-scale density logging tool is divided into four steps:

[0051] Calibration step 1: The instrument motion servo motor 17 drives the instrument motion screw 21, which in turn drives the density logging instrument 6 to move to the right, sending the density logging instrument 6 into the aluminum block 11 and ensuring that the probe of the density logging instrument 6 is positioned inside the aluminum block 11. According to the position of the tail of the density logging instrument 6, the auxiliary horizontal lifting mechanism 10 on the left side of the aluminum block 11 is operated to move upward, and the auxiliary horizontal lifting mechanism 10 in the middle is operated to move upward. The servo electric cylinder 19 is controlled to move the follower nylon wheel 18 upward, so that the density logging instrument 6 is closely attached to the inner wall of the aluminum block 11, and the density logging instrument 6 is kept horizontal from side to side, thereby increasing the calibration accuracy of the density logging instrument 6. The tightening mechanism in the aluminum block 11 is controlled to push up the density logging instrument 6, so that the probe of the density logging instrument 6 is closely attached to the inner wall of the aluminum block 11, thereby increasing the calibration accuracy.

[0052] Calibration step 2: After completing step 1, release the pressure in the tightening mechanism in the aluminum block 11, the auxiliary horizontal lifting mechanism 10 on the left side of the aluminum block 11, and the auxiliary horizontal lifting mechanism 10 in the middle. After the density logging instrument 6 falls back downward, operate the plate motion servo motor 22 of the magnesium plate motion assembly 23 to drive the plate screw 24, thereby driving the magnesium plate 8 to move rightward, and send the magnesium plate 8 into the aluminum block 11, between the density logging instrument 6 and the inner wall of the aluminum block 11. Operate the auxiliary horizontal lifting mechanism 10 on the left side of the aluminum block 11 to move upward, and operate the auxiliary horizontal lifting mechanism 10 in the middle to move upward, control the servo electric cylinder 19, and adjust the position of the follower nylon wheel 18 to make the density logging instrument 6 close to the magnesium plate 8, the magnesium plate 8 close to the inner wall of the aluminum block 11, and keep the density logging instrument 6 horizontal, thereby increasing the calibration accuracy of the instrument. The tightening mechanism in the aluminum block 11 is controlled to push up the density logging instrument 6, so that the probe of the density logging instrument 6, the magnesium plate 8 and the inner wall of the aluminum block 11 are closely fitted together, thereby increasing the calibration accuracy.

[0053] Calibration step three: After completing step two, release the pressure in the tightening mechanism within the aluminum block 11, the auxiliary horizontal lifting mechanism 10 on the left side of the aluminum block 11, and the auxiliary horizontal lifting mechanism 10 in the middle. After the density logging instrument 6 falls back downward, operate the plate motion servo motor 22 of the magnesium plate motion assembly 23 to drive the plate screw 24, thereby driving the magnesium plate 8 to move leftward and move outside the aluminum block 11. Control the instrument motion servo motor 17 to drive the instrument motion screw 21, thereby driving the density logging instrument 6 to continue to move rightward, sending the density logging instrument 6 into the magnesium block 13 and ensuring that the probe of the density logging instrument 6 is positioned within the magnesium block 13. Operate the auxiliary horizontal lifting mechanism 10 in the middle and the auxiliary horizontal lifting mechanism 10 on the right side of the magnesium block 13 to move upward. Control the servo electric cylinder 19 to move the follower nylon wheel 18 upward, so that the density logging instrument 6 is closely attached to the inner wall of the magnesium block 13 and the density logging instrument 6 is kept horizontal, thereby increasing the calibration accuracy of the instrument. The tightening mechanism in the magnesium block 13 is controlled to push up the density logging instrument 6 so that the probe of the density logging instrument 6 is closely attached to the inner wall of the magnesium block 13, thereby increasing the calibration accuracy.

[0054] Calibration step four: After completing step three, release the pressure in the tightening mechanism in the magnesium block 13, the auxiliary horizontal lifting mechanism 10 in the middle, and the auxiliary horizontal lifting mechanism 10 on the right side of the magnesium block 13. After the density logging instrument 6 falls back downward, operate the plate motion servo motor 22 of the steel plate motion assembly 16 to drive the plate lead screw 24, thereby driving the steel plate 15 to move leftward, and send the steel plate 15 into the magnesium block 13, between the density logging instrument 6 and the inner wall of the magnesium block 13. Operate the auxiliary horizontal lifting mechanism 10 in the middle to move upward, and operate the auxiliary horizontal lifting mechanism 10 on the right side of the magnesium block 13 to move upward, control the servo electric cylinder 19 to adjust the position of the follower nylon wheel 18, so that the density logging instrument 6 is close to the steel plate 15, the steel plate 15 is close to the inner wall of the magnesium block 13, and the density logging instrument 6 is kept horizontal, thereby increasing the calibration accuracy of the instrument. The tightening mechanism in the magnesium block 13 is controlled to push up the density logging instrument 6, so that the probe of the density logging instrument 6, the steel plate 15 and the inner wall of the magnesium block 13 are closely fitted together, thereby increasing the calibration accuracy.

[0055] After completing step 4, the pressure in the tightening mechanism within the magnesium block 13, the auxiliary horizontal lifting mechanism 10 in the middle, and the auxiliary horizontal lifting mechanism 10 on the right side of the magnesium block 13 is released. After the density logging instrument 6 falls back downward, the plate motion servo motor 22 of the steel plate motion assembly 16 is operated to drive the plate screw 24, thereby driving the steel plate 15 to the right, so that the steel plate 15 moves outside the magnesium block 13. The instrument motion servo motor 17 is controlled to drive the instrument motion screw 21, thereby driving the density logging instrument 6 to the left, so that the density logging instrument 6 moves out of the magnesium block 13 and the aluminum block 11. The clamping cylinder 4 is controlled to move the power nylon wheel 5 upward, and the servo electric cylinder 19 is controlled to move the follower nylon wheel 18 downward, so that the density logging instrument 6 falls onto the movable support 1 and the auxiliary support Ⅰ7.

In the remote control room 35, the control cabinet 34 can be operated to perform calibration operations on the density logging instrument 6, thereby reducing the time workers are exposed to radioactive sources and reducing radiation damage.
