Abstract

A sheave wheel includes a housing; a wheel attached to the housing and configured to rotate relative to the housing; a depth and tension measurement system attached to the housing and configured to measure a parameter associated with the wheel; and a local control system attached to the housing and configured to exchange information associated with the measured parameter in a wireless manner with a ground control system.

First claim

What is claimed is:

1. A wireline system for well exploration, the system comprising:
a wireline to be lowered into the well;
a top sheave wheel configured to hold the wireline aligned and above a head of the well;
a bottom sheave wheel configured to hold the wireline aligned with a wireline truck; and
a ground control system configured to receive, in a wireless manner, a measured parameter from the top sheave wheel,
wherein the top sheave wheel includes,
a depth and tension measurement system that is configured to measure the parameter,
a processor that is electrically connected to the depth and control measurement system,
a memory that stores the measured parameter, and
a transceiver that is controlled by the processor and is configured to transmit the measured parameter, in a wireless manner, to the ground control system.

2. The system of claim 1 , wherein the top sheave wheel comprises:
a housing;
a wheel attached to the housing and configured to rotate relative to the housing; and
the depth and tension measurement system is attached to the housing.

3. The system of claim 1 , wherein the depth and tension measurement system includes a rotation measurement device that measures a rotation of the wheel.

4. The system of claim 2 , wherein the processor translates a rotation of the wheel into a length traveled by the wireline around the wheel of the top sheave wheel.

5. The system of claim 4 , wherein the wireline is attached to a gun.

6. The system of claim 1 , wherein the depth and tension measurement system includes a tension measurement device that measures a tension in a wheel of the top sheave wheel.

7. The system of claim 2 , wherein the depth and tension measurement system comprises:
a rotation measurement device that measures a rotation of the wheel; and
a tension measurement device that measures a tension in the wheel.

8. The system of claim 1 , further comprising:
a power generator attached to the top sheave wheel and electrically connected to the depth and tension measurement system and configured to generate electrical energy from a rotation of a wheel of the top sheave wheel to power the depth and tension measurement system.

9. A method for lowering a wireline into a well, the method comprising:
attaching a top sheave wheel to a crane;
placing the wireline over the top sheave wheel;
lowering the wireline into the well;
measuring with a depth and tension measurement system, which is attached to the top sheave wheel, a parameter associated with the wireline; and
transmitting in a wireless manner the measured parameter, from the top sheave wheel to a ground control system,
wherein the top sheave wheel comprises:
a processor that is electrically connected to the depth and control measurement system;
a memory that stores the measured parameter; and
a transceiver that is controlled by the processor and is configured to transmit the measured parameter, in a wireless manner, to the ground control system.
