Embodiments of the invention provide a method and a device for predicting space distribution of a lamellation crack. The method comprises the following steps of dividing a shale crack phase accordingto core data and lamina data; determining a logging response characteristic of the shale crack phase according to logging information; determining longitudinal distribution of the shale crack phase ona single well according to the logging response characteristic of the shale crack phase; establishing an equation by taking the longitudinal distribution of the shale crack phase on the single well as a constraint and a shale crack phase index as a target function; and predicting the space distribution of the lamellation crack according to the equation. According to the embodiments of the invention, the equation is established by taking the shale crack phase index as the target function, so that a space distribution rule of the lamellation crack can be evaluated and predicted, and reliable information is provided for shale oil and gas exploration and development, and thus the unconventional oil and gas exploration and development risk cost is reduced, and the exploration and development efficiency is improved.
Description
technical field [0001] The embodiments of this specification relate to the field of unconventional oil and gas exploration and development, and in particular to a method and device for predicting the spatial distribution of lamellae. Background technique [0002] Shale oil and gas is a very important unconventional oil and gas resource in my country. It has a wide distribution range and a huge amount of oil and gas resources. It is the main unconventional oil and gas resource that is currently being explored and developed in my country. The development of natural fractures in shale reservoirs has an important impact on the enrichment and preservation of shale oil and gas. How to evaluate and predict the distribution of shale fractures is of great significance to the exploration and development of shale oil and gas. Compared with other reservoirs, in addition to structural fractures, shale reservoirs also develop lamellation fractures, which affect the exploration and develo...
