4. An accurate counting system: The oil logging winch is equipped with a precise counting device to ensure that the probe instrument has an accurate depth position during the lifting or lowering of the cable.
1）Oil logging winch: The cables used in logging, perforating, and other operations are wrapped around the winch drum, which is turned by the power of the automobile engine, so as to control the cable in the well at the required speed.
2）Logging cable: Conveying various downhole instruments and tools; Supply power and transmit control signals to downhole instruments; Transmit signals from downhole instruments to the surface.
3）Wellhead pulley: A device that changes the direction of a cable.
4）Tension meter: Used with the wellhead pulley, the tension of the logging cable is changed into an electrical signal and sent to the tension panel of the winch for display. Through the change of cable tension, the operation of the downhole instrument and cable can be accurately judged.
5）Cable torpedo: The purpose of cable torpedoes is to connect with various cable heads.
6）Bridle: Connecting cables and downhole instruments; it can be quickly connected and disassembled, and can ensure that the cable core is connected with the instrument wire and the insulation is good.
7）Downhole instruments: Collect downhole physical information and convert it into electrical signals for transmission to the well.
1. Swing: When lifting, the lifting hook should be used to lift, gently lift, do not collide with other parts.
2. Install: The CJ series logging wire rope winch should be installed on flat and solid ground, and the distance from the well platform should be kept to keep the Angle between the steel wire and the horizontal about 10° (elevation Angle). When it is required to be installed on the well table, a random attachment pulley must be used to maintain this Angle.

The Use of Oil Logging Winch
1. Hydraulic system oil: In the summer, L-HM46 hydraulic oil is used. In winter, L-HM32 hydraulic oil is used.
2. Oil in gearbox: In summer, L-AN68 gear oil is used. In winter, L-AN46 gear oil is used.
3. The wire is wound in the groove of the counter drive wheel, after one loop, press down on the extension with the compression wheel.
4. Preparation of the oil logging winch before use
(1) Check whether bolts and nuts are tightened.
(2) Check whether the hydraulic oil in the tank is within the range of the oil line.
(3) Check whether the lubricating oil in the gearbox is inside the oil label nut.
(4) Check whether each valve is flexible.
(5) Whether the chain tension is appropriate, otherwise it should be adjusted.
(6) Check that the counter is wound correctly.
(7) Check that the three-position four-way valve handle is in a neutral position.
(8) Check that the brakes are reliable.
(9) Check that the trimmer valve is in the minimum position.
(10）A measuring device for connecting logging wire rope winches.
5. After the inspection, prepare to drive
Turn on the power to start the motor test run, and observe whether the oil pump steering is correct, otherwise, it should be a commutated connection.
6. Start-up of oil logging winch
(1) Turn on the power to start the motor, use the motor to drive the gear pump, and run empty for 2-5min.
(2) Turn the handle of the gearbox to the desired gear, turn the three-position four-way valve to forward or reverse, and then adjust the trimmer valve to make the drum rotate from slow to fast.
(3) In order to ensure the safe use of the wire rope, the maximum hydraulic working pressure of the winch is controlled by the overflow pressure of 15.7MPa.
(4) During operation, often listen for abnormal sounds. Once found should immediately stop for inspection.
7. Stopping and reversing of logging winch.
(1）The parking of the oil logging winch can pull the three-way four-way valve to the parking position. In case of special circumstances, the brake handle can also be turned to brake.
(2）Drum reversing operation: Change the hydraulic motor steering to achieve, the fine-tuning valve is closed until the motor speed is 0, Turn the three-position four-way valve into reverse.
8. Winch shift
(1）Mechanical speed change: The Three-position four-way valve handle must be pulled to the neutral position, and the transmission handle must be pulled. To Ⅰ, Il position, in turn, to achieve variable speed. Mechanical speed changes shall not be used during operation.
(2）In each gear of the mechanical speed change, the hydraulic step-less speed change is realized by adjusting the opening of the fine-tuning valve.
Maintenance of Oil Logging Winch
The maintenance of the logging winch is the main measure to ensure normal operation and prolong the service life of the logging winch, which must be carried out carefully.
1. Current maintenance
(1) Check each connecting part and each pipe joint for oil leakage phenomenon, find out the cause, and eliminate it in time.
(2) Check whether bolts, nuts, and screws are loose, and remove any problems in time.
(3) Pay attention to whether the pressure gauge and counter work normally, if not normal should be repaired or replaced in time.
(4) Fill the gap between the loose edges of the chain and the inner and outer chains, and double-row chain coupling with oil.
(5) Hydraulic components should be kept as clean as possible to facilitate inspection and fault detection. Hydraulic components should be disassembled as little as possible. During maintenance, the environment and parts should be kept clean.
(6) When the hydraulic system has air, it may produce phenomena such as rebound, noise, and poor operation. At this time, the body parts can be repeatedly moved to discharge air multiple times. If still cannot be discharged, unscrew the tubing joint, and discharge the air.
(7) The temperature of the hydraulic system shall not exceed 90℃. Bearings such as gearbox and drum support shall not exceed 60 ° C. If there is overheating, check whether the system is blocked, whether the relief valve is faulty, and whether the bearings and gears of each part have abnormal wear.
(8) The brake handle should be flexible, find obvious damage, and timely replacement.
(9) Brake handle should be flexible, if not flexible timely maintenance.
(10）Always pay attention to the situation of wire rope or wire, find that there are broken or serious nicks, and cut off in time to avoid the phenomenon of pulling.
2. First class maintenance
After running the log winch for 50 to 100 hours, in addition to daily maintenance, the following maintenance should be carried out.
(1) Clean the fuel tank and transmission filter using clean kerosene or gasoline.
(2) Check whether the nut of the tension wheel is loose. If it is loose, adjust the chain before tightening the nut.
(3) Check the hydraulic oil transmission lubricating oil, if there is serious pollution should be released, and clean it with clean kerosene or gasoline, according to the provisions of the new oil.
(4) Add butter to each butter nozzle.
(5) Grease the lead screw of the automatic wiring mechanism.
3. Second level service
Running 500 to 1000 hours, in addition to daily and primary maintenance should also be carried out the following maintenance.
(1) Clean fuel tank and hydraulic line with clean kerosene or gasoline.
(2) Check whether the internal leakage of each hydraulic component is large, if it is found to be large, it should be repaired.
(3) Check the chain and sprocket wear, if large, should be replaced.
(4) Check the gear of the gearbox, if the abnormal wear is serious, it should be replaced.
(5）Pay attention to the double chain coupling, found abnormal wear, and should be replaced.
(6）Check the wear of the guide pin and lead screw of the automatic wiring mechanism, and replace it if there is serious wear.
Caution
1. In the use of the logging wire rope winch, attention should be paid to the value of the pressure gauge, not to exceed the recommended maximum use pressure of each grade, so as not to cause the rope to break. (I gear pressure ≤9.0Mpa, II gear pressure ≤15.7Mpa)
2. Pay attention to the amount of fuel in the tank and gearbox.
3. Do not pull the gearbox handle during the rotation of the motor to avoid damage to the gearbox.
4. Do not use the three-position four-way valve directly when the motor is rotating. The fine-tuning valve should be closed first so that the motor speed is 0, and then use the Three-position four-way valve to reverse, so as not to damage the motor.
5. In normal use, do not easily use the brake handle.
6. The relief pressure of the relief valve components has been adjusted before leaving the factory, and it is not allowed to be adjusted at will in use.
7. The pressure wheel of the counter should be moderately relaxed.
