DRILLING PARAMETER RECORDER Russian patent published in 2007 - IPC E21B44/00 E21B47/22 

FIELD: automatic control systems specially adapted for well drilling operations used for drilling and operation of wells, blast-holes and for other procedures.

SUBSTANCE: recorder comprises body with electronic unit and power supply unit arranged in the body. Electronic unit includes microprocessor with executive program, x and y plane accelerometer, nonvolatile memory microcircuit, calendar time timing means, temperature sensor and data input-output port, which provides data output and input in computer with the use of communication interface. Microprocessor output is connected to the first input of nonvolatile memory microcircuit. X and y plane accelerometer is linked to the first microprocessor input, calendar time timing means is communicated with the second microprocessor input and temperature sensor output is connected to the third microprocessor input. Temperature sensor input is connected to power supply unit. Input and output of data input-output port are linked to microprocessor. Input of data input-output port is connected to power supply unit. Calendar time timing means input, the forth microprocessor input and accelerometer input are linked to the second nonvolatile memory microcircuit input.

EFFECT: increased accuracy and information content due to recording of new parameters, hydraulic downhole motor rotation speed, vertical tool vibration, temperature measurement and data binding to calendar time with high accuracy and decreased size.
