Chinese Patent Publication (Announcement) No. CN2193426, published on March 29, 1995, discloses a hydraulic well testing vehicle, which consists of a special vehicle modified by adding a closed compartment to the chassis of a truck and a well logging device. The winch of the device is driven by the output power of the vehicle transmission, which is characterized in that the transmission system of the winch is a hydraulic transmission system, that is, a power take-off is installed on the side of the automobile gearbox, and the power is directly drawn from the gearbox; Drive the hydraulic pump of the hydraulic transmission system through the coupling mechanism; then the hydraulic motor drives the winch through the coupling mechanism; the hydraulic transmission system adopts the integrated block hydraulic distributor. strong
With the rapid development of oil production in oil fields, this control system can no longer meet the needs of modern production in oil fields
