Automatic pumping depth metering apparatus for oil testing operation

The utility model discloses an automatic pumping depth metering apparatus for oil testing operation in the oil field, comprising an elastic compactor 1, a pinch roller 2, a counter wheel 3, a rotational slide device 4, a rotary axle 5, a left bearing seat 6, a right bearing seat 7, a transmission axle 8, and a counter 9. The elastic compactor 1 is arranged on the pinch roller 2, and the counter wheel 3 measuring the length of the steel cord is installed on the rotational slide device 4. The rotational slide device 4 and the counter wheel 3 are arranged on the rotary axle 5. The counter 9 is connected with the rotary axle 5 through the transmission soft axle 8. The left bearing seat 6 and the right bearing seat 7 are respectively arranged on the two sides of the bottom of the apparatus, the time is saved, the labor is saved, and the depth of climbing down for drawing steel wire cord can be directly read. Without a code cord, the oil well mouth packing case is fine in sealing, the error is small, the design is reasonable, and the error in 2000 meters is smaller than (+/-) 1 meter. The accuracy of the data of the trial oil well output is not affected, and the utility model can check the height of the liquor surface in the well and master the height of the liquor surface in the pumping well.
