  • Page 2: General

    1.0 GENERAL The AM5K Wireline Measuring Device is a compact and lightweight device for measuring both wireline depth and tension. The device is designed to be mounted to the spooling arm of a wireline unit. It is unique to other measuring devices in that it measures both depth and tension on wireline cables from .190”...

  • Page 3: System Description

    2.0 SYSTEM DESCRIPTION DEPTH MEASUREMENT: The AM5K Measuring Head uses dual spring-loaded measuring wheels to measure the amount of wireline moving to and from the borehole. The measuring wheels are coupled to one or two optical encoders that transmit electrical signals via a cable to the hoistman’s panel and/or logging computer.

  • Page 4: Operation

    OPERATION SPOOLING ARM INSTALLATION – OVERHEAD SPOOLING ARM Install the measuring head on to the spooling arm by using the top adapter mount assembly to mount to an overhead spooling arm. The mount is designed to mount with a standard U-joint yoke. MOUNTING YOKE AM5KA Measure Head RevL...
  • Page 5 Make sure that the head can freely sit on the wireline. If the mounting arrangement will not let the head travel up and down freely and if the cable puts a upward or downward force on the measuring head, this force will cause an offset to the tension measurement which will result in an incorrect tension reading.
  • Page 6 SPOOLING ARM INSTALLATION – ASEP SPOOLING ARM Use this mount if the measuring head is to be installed on a unit with an ASEP Autospooler. The mount is installed on the horizontal bar. The head is pinned to the mount and can be easily removed by removing the pins. Parent Item Number: AM5KA243 KIT MOUNTING AM5K ASEP OH ARM Component...

  • Page 8 CABLE INSTALLATION To install cable, first open the wheels by shifting the red release handles. Next, remove the push pin, and hinge the head open. Lifting up on the wireline cable makes it easier to remove the push pin. The cable can now be inserted or removed. Close the red release handles to tighten the wheels against the wireline.
  • Page 9 CABLE REMOVAL UNDER LOAD 3.4.1 If under load, the load will need to be removed from the device prior to removing the retaining pin. A “C-clamp" or a nylon "ratchet strap" can be used to remove the load. 3.4.2 Install a C-Clamp across the top and bottom frames as shown in the drawing below.
  • Page 10 CHANGING CONFIGURATION BETWEEN OPEN HOLE AND CASED HOLE A measuring head configured for open hole will typically contain a magnetic mark detector and a 2 encoder. Cased hole operations rarely require a magnetic mark detector and typically use only one encoder. If the head is configured for open hole, no changes are required to run it on a cased hole unit.
  • Page 11 3.6.2 To install the deep grooved tension wheel, a modified load pin is available that is calibrated to so the K factor of 1 be used. 3.6.3 The deep grooved tension wheel can be used with a standard load pin. If it is, the Load Cell K factor must be changed to compensate for the reduced bend angle of the cable (refer to 3.6.1) 3.6.4 The Load Pin and grooved tension wheel can be ordered from Kerr...
  • Page 12 SYSTEM OPERATION Determine cable size to be used – .490" to .190” Since the wireline cable actually bends around the tension wheel, the bend radius of the wireline cable will affect the tension measurement. These corrections are automatically made in the 5762XA Kerr Hoistman's panel by selecting the proper cable size using the menu.

  • Page 13: Maintenance And Repair

    MAINTENANCE AND REPAIR PRE-JOB CHECK Each time the system is used perform the following steps: Verify that the AM5K is properly and securely attached to the spooling arm. Several different mounting kits are available for different types of spooling arms. Verify that the depth measuring wheels are clean and that no groove has been worn into the measuring wheel surface.
  • Page 14 MONTHLY MAINTENANCE Visually inspect the interiors of the electrical connectors for the encoders and electronic load axle for dirt and evidence of insulation breakdown. Clean or replace as necessary. Install dust caps on the connectors if the cables are removed. Manually rotate each wheel by hand to verify its condition.

  • Page 16 ASSEMBLY / DISASSEMBLY PROCEDURES 4.4.1 MEASURING WHEEL, SHAFT, AND BEARING REMOVAL Either measuring wheel can be removed from the measuring head. First shift the red release handle to move the wheel away from the frame. Next remove the encoder with its adapter. On the later model heads, the wheels (item 22) are keyed onto the shaft and can be removed simply by removing the screw holding the wheel to the shaft (item 85).
  • Page 17 4.4.3 ELECTRONIC LOAD PIN REMOVAL The electronic load pin is held in place by one retaining ring on the outer end of its shaft. Remove the retaining ring. The load pin can then be removed from the mounting frame. 4.4.4 BACKUP DEPTH MAGNETIC PICKUP REMOVAL AND INSTALLATION The backup depth magnetic pickup is mounted to the encoder adapter.
  • Page 18 Use a screw driver to capture the end of the spring (see photo). The end cap and the pin can now be removed (see Photo) AM5KA Measure Head RevL Sep 2007 Page 18 of 50...
  • Page 19 Use a hook to pull the spring out far enough to remove the screwdriver (Careful not to bend the spring). Remove the floating encoder assembly. Repeat for the other side. Remove anti-rotation screw (if equipped). Remove snap ring and pull out sliding shaft. Remove the wheel assembly.
  • Page 20 Insert a 3/16” x 1/2” long roll pin into the hole. Do not use a longer roll pin as it will put the wheel into a bind. AM5KA Measure Head RevL Sep 2007 Page 20 of 50...
