ENVIRONMENTAL SEVERITY MEASUREMENT TOOL

摘要

An environmental severity measurement tool measures acceleration along 3 axes to determine shock and vibration affecting a downhole tool in which the environmental severity measurement tool is disposed. The environmental severity measurement tool includes a replaceable battery and electronics disposed within an external housing. A pin provides a way to ensure the environmental severity measurement tool is oriented in a known orientation. Data sampled by the tool can be downloaded from the tool to an external device through a connector port of the electronics. Software in the tool controls the operation of the tool and can he configured from an external device.

1. An environmental severity measurement tool, comprising:
an external housing, configured for disposal in a downhole tool, open at one end; a replaceable battery, disposed in the external housing; an electronics portion disposed within the external housing, comprising:
a processor, electrically connected to the battery;a connector port configured to allow connection to an external device, coupled to the processor;three accelerometers configured to measure acceleration along three axes, coupled to the processor; anda memory, coupled to the processor on which is stored software for causing the processor to:
sample measurements from the three accelerometers;calculate acceleration along three axes;store calculated acceleration data; anddownload the stored acceleration data to the external device via the connector port.
