Absolutely NO. Do not use section breaks as page breaks. You absolutely don't want 3000 sections in your document. I would say you also don't want all those hard page breaks either.

The advice to put that information in a footer and allow the content to flow across pages is still the BEST recommendation for you UNLESS you need the result to exactly match the pagination, formatting etc of the original PDF - in which case, why bother converting to Word.

If your point of bringing the content into Word is to allow you to clean it up and reformat the content, then you should do it as efficiently as possible. The "4 lines on every page of 3000" in your original question SOUNDS AND LOOKS like it should be in the footer which is why it was recommended to you. If you choose not to do that, then please explain how your finished document should be different to the source PDF?
