Abstract
In accordance with some embodiments of the present disclosure, a method for vibration control for a wellbore logging tool is disclosed. The method may include measuring an initial output signal of the wellbore logging tool. Additionally, the method may include generating a first braking signal based on the initial output signal of the wellbore logging tool. The method may further include transmitting the first braking signal to the wellbore logging tool. The first braking signal may be designed to dampen the vibration of the wellbore logging tool.
Claims20
A method of vibration control for a wellbore logging tool, the method comprising:
- generating, by vibration of an acoustic transmitter of the wellbore logging tool, an output of an amplifier of the wellbore logging tool, wherein the amplifier is coupled to the acoustic transmitter;
- sending the output to a braking signal generator of the wellbore logging tool;
- generating a first braking signal based on the output;
- transmitting the first braking signal to the amplifier to dampen the vibration of the acoustic transmitter;
- suppressing, after the first braking signal is transmitted to the acoustic transmitter, an input signal to the wellbore logging tool for a duration of time;
- providing a subsequent output signal of the wellbore logging tool;
- determining whether a subsequent vibration of the wellbore logging tool is below a threshold;
- and
- based on the determination:
- generating a second braking signal based on the subsequent output signal of the wellbore logging tool;
- and
- transmitting the second braking signal to the wellbore logging tool, the second braking signal designed to reduce the subsequent vibration of the wellbore logging tool.
A wellbore logging system, comprising:
- a wellbore;
- a conveyance;
- a wellbore logging tool connected to the conveyance and suspended in the wellbore;
- and
- a vibration control system communicatively coupled to the wellbore logging tool, the vibration control system including:
- a processor;
- and
- a memory communicatively coupled to the processor with computer program instructions stored therein, the instructions, when executed by the processor, cause the processor to:
- generate, by vibration of an acoustic transmitter of the wellbore logging tool, an output of an amplifier of the wellbore logging tool, wherein the amplifier is coupled to the acoustic transmitter;
- sending the output to a braking signal generator of the wellbore logging tool;
- generate a first braking signal based on the output;
- transmit the first braking signal to the amplifier to dampen the vibration of the acoustic transmitter;
- suppress, after the first braking signal is transmitted to the acoustic transmitter, an input signal to the wellbore logging tool for a duration of time;
- provide a subsequent output signal of the wellbore logging tool;
- determine whether a subsequent vibration of the wellbore logging tool is below a threshold;
- and
- based on the determination:
- generate a second braking signal based on the subsequent output signal of the wellbore logging tool;
- and
- transmit the second braking signal to the wellbore logging tool, the second braking signal designed to reduce the subsequent vibration of the wellbore logging tool.
