Lead Pattern

Application
Lead pattern is used as a fishing tool in petroleum industry, for detecting the status of fish-top, inside diameter and shape of the casing.

Advantages
The lead pattern is a one-piece, cone-shaped fishing tool. Its unique design prevents the pattern from dropping off during drilling, and thus helps raise the fishing efficiency.

The do's and don'ts
1. The diameter of lead pattern should be 48mm smaller than the inner diameter of casing.
2. Pattern under pressure of 0.5-1 t/inch, for only one time.
3. Handle the lead carefully for transport and storage.
