Inclined shaft core fissure orientation method

The invention relates to the field of the exploitation and development of oil and gas fields, and in particular relates to an inclined shaft core fissure orientation method. The method is characterized by comprising the following steps: on the basis of drilling data, calculating well deviation information of a coring interval, calculating the real attitude of a rock stratum according to earthquake data, determining an apparent dip of the core fissure and an angle between the fissure apparent inclination and apparent inclination of the rock stratum according to the core data, designing an inclined shaft core fissure orientation concept on the basis, deriving a corresponding algorithm, and realizing the accurate orientation of the core fissure. By adopting the method, the problem that the inclined shaft core fissure cannot be orientated can be solved, the inclined shaft core fissure orientation accuracy is improved, and the practical value on multiple aspects such as accurately determining the permeation rate advantageous direction of a reservoir stratum of the oil and gas field, the relative position relation of a water filling well and an oil recovery well, direction of ancient stress field in the crack generation period, reasonable layout and development of well networks can be realized.
