The phrase "a preliminary method" is correct and usable in written English.
It can be used when referring to an initial approach or technique that is intended to be a starting point for further development or research.
Example: "In our study, we employed a preliminary method to gather initial data before refining our approach."
Alternatives: "an initial technique" or "a preliminary approach".
