Research on Five Dimensional Seismic Fracture Prediction Technology for Shale Oil
[Purposes]Recently,multiple shale oil exploration wells have been drilled in LN Depression,opening up a new era of shale oil exploration.In the exploration and development of shale oil,it is crucial to accurately predict fractures.Therefore,it is necessary to study fracture prediction techniques.[Meth-ods]This article focuses on the application of five dimensional seismic data,utilizing pre stack trace data in the OVT domain for azimuth offset optimization and partial stacking of trace zones.Different anisotro-pic fracture prediction methods are analyzed for shale oil,forming a set of five dimensional fracture pre-diction techniques for shale oil in the LN region.[Findings]Based on the difference in amplitude and ori-entation,the fracture prediction results can clarify the development intensity and orientation of shale oil in the LN depression of the study area,and guide the exploration and deployment of shale oil.[Conclu-sions]There are many methods for analyzing the anisotropy of five dimensional fractures in shale oil.For different geological conditions in different work areas,it is necessary to gradually analyze and compare them,and select the method suitable for the work area for research,in order to achieve the best effect.
