Full-Scale Tests Prove it Practical to 'Drill' Holes with Coiled Tubing Using Only Acid; No Motors, No Bits.

摘要

This paper details the results of a test program designed to show that acid can be used to construct clean, defined wellbores in carbonate rocks. The results show that with the correct choice of nozzle layout, acid strength and jetting pressure, holes can be constructed at commercially attractive rates.
