CABLE LENGTH AND SPEED DETERMINING DEVICE DURING PULLING AND RUNNING OPERATIONS AT WELL Russian patent published in 2019 - IPC G01B7/04 G01P3/00 

FIELD: measurement technology.

SUBSTANCE: invention relates to cable length and speed determining device during lowering and lifting operations at well. In the cable length and speed determining device during the lowering and lifting operations on the well, the device for supplying the coiled cable to the well is made in the form of a carriage with fixed rotating upper and lower rollers forming a cable supply channel, lower rollers are installed with possibility of their position adjustment relative to upper rollers, the carriage is fixed on the movable bracket by means of a swivel having the possibility of adjusting the height position relative to the bracket, and as measurement unit there used is device for contactless measurement of length and speed, fixed on swivel above device for cable supply into well, and bracket is fixed with possibility of rotation on vertically installed post with possibility of its attachment to frame structure of installation for winding and cable unwinding.

EFFECT: design of a device for simultaneous determination of the cable length and speed during descent into the well and its lifting with the possibility of its use for a cable of any standard size and complete with a unit for winding and unwinding a cable of any design.
