Strain Gauge Pressure - Wellbore Temperature (PTC43C-A)

Pressure-Temp-CCL PTC43C Tool is mainly used for depth correction and leakage detection. This tool integrates three parameters of Pressure, Temperature & CCL, and can be connected with other GOWell logging tools for combination logging. This tool is available in memory mode. 

 

DESCRIPTION

PTC43C is mainly comprised of the reference power supply circuit, MCU control circuit, CCL circuit, Pressure processing module, transmission circuit, and wellbore temperature circuit.

Pressure Measurement Principle

 

The pressure section adopts piezoresistive pressure which produce different resistance according to pressure. 

 

Wellbore Temperature Measurement Principle

Wellbore temperature measurement circuit uses a PT100 platinum thermal resistor which is linearly responsive with the ambient temperature. 

 

CCL Measuring Principle

 

CCL section is made up of induction coil, magnetic steel and amplifier. The induction coil is located between the four magnetic steels. When the tool meets the casing collar while it’s moving in the casing, the magnetic field strength in the coil changes correspondingly to the change of the magnetic flux surrounding magnetic objects in order to generate induction voltage. 

Pressure-Temp-CCL PTC43C Tool is mainly used for depth correction and leakage detection. This tool integrates three parameters of Pressure, Temperature & CCL, and can be connected with other GOWell logging tools for combination logging. This tool is available in memory mode.
