The definition below is one definition given by the service company, Schlumberger:
"A conceptual model for a style of hydrocarbon accumulation used by explorationists to develop prospects in a basin, region or trend and used by development personnel to continue exploiting a given trend. A play (or a group of interrelated plays) generally occurs in a single petroleum system."
Wikipedia has a somewhat different answer:
In geology, a petroleum play, or simply a play, is a group of oil fields or prospects in the same region that are controlled by the same set of geological circumstances.
From both definitions, it is clear that the play is a logical grouping of hydrocarbon accumulations based on geological considerations.
See links. You may find considerable more discussion by conducting an internet search. Also, the definition is dependent on the context in which it is used.
