The method as shown in fig. 1 may be performed by an apparatus for identifying a marine carbonate beach phase reservoir, and the apparatus may be the apparatus for identifying a marine carbonate beach phase reservoir as shown in fig. 2. And the specific device of the device can be set according to the actual requirement, and the embodiment of the application is not limited to this. For example, the device may be a computer, a server, or the like. Specifically, the method as shown in fig. 1 includes:
and S110, identifying a top-bottom interface of the three-level sequence according to seismic interpretation, field outcrop or drilling logging data. Wherein the top-bottom interface comprises a top interface and a bottom interface.

Optionally, for field outcrop, the top-bottom interface of the stratum is available, and the change of the stratum relative to the sea level can be determined by observing the change of lithology, namely, the rise and fall of the sea level can be reflected. For example, it is deepwater sedimentary mudstone; as another example, a bird's eye configuration with shallow water deposits, and the like.

Specifically, under the condition that global sea level changes can be generally reflected by changes of carbon and oxygen isotopes of whole rocks and relative changes of sedimentary water bodies in the sedimentary stratum forming process can be represented by a specified logging curve, the change curve of the carbon and oxygen isotopes of the whole rocks in the field and the specified logging curve can be put together for comparison, and if the trends of the two curves are consistent, the three-level sequence is determined to be controlled by the global sea level changes; if the three-level sequence is inconsistent, determining that the three-level sequence is controlled by the dual-effect influence of global sea level change and regional structure movement.
