Carbonate rock reservoir space analysis method

The invention discloses a carbonate rock reservoir space analysis method. The method comprises the following steps: a, creating a sequence stratigraphic framework domain; b, creating a tectonic-basin burial evolution history grillwork domain; c, creating a fluid system grillwork domain to obtain a fluid type and characteristics formed by modifying and adjusting a carbonate reservoir space; in combination with the steps a and b, obtaining the sequential sequence relation of the fluid type to carbonate reservoir space development, transformation and adjustment; and d, through a three-domain analysis method, finally obtaining geological backgrounds of different structures, deposition and the like, a reservoir space development mechanism and main control factors, so that favorable reservoir space distribution is obtained, and a favorable reservoir development area is indicated. The method can effectively guide carbonate rock oil and gas exploration and development area selection and well position deployment under
