Casing Collar Locator (CCL)

The Casing-Collar Locator (CCL) is crucial for depth control in cased-hole logging, essential for correlating depths between cased-hole and openhole logs.

It utilizes a coil-and-magnet setup with a downhole amplifier, detecting collar enlargements in the casing via magnetic field distortions.

This generates a voltage spike known as a collar “kick,” recorded at the surface. CCLs operate in wireline or slickline modes, with real-time slickline tools converting spikes to tension changes for immediate surface detection.

Coiled-tubing applications use pressure spikes transmitted through fluid for detection due to weight constraints.

Tractors in deviated wells can also provide depth control by producing a CCL during operations.

Description

Casing Collar Locator (CCL)

The probe is composed of a coil and four magnets, the magnets are divided into two groups and are installed at the upper end and the lower end of the coil respectively, so that the coil is in a constant magnetic field, when the instrument passes through the joint hoop, the magnetic field lines are rearranged, the coil is in a changing magnetic field at this time, so that an alternating current signal is induced in it, the electrical signal is amplified and converted into frequency, this frequency is counted by the single-chip microcomputer on the instrument, and is sent to the telemetry short section when the telemetry short section is addressed, and then sent to the ground by the telemetry short section code through the cable. This completes the measurement of the casing ferrule.
