Research on Fracture Prediction of Permian Volcanic Reservoirs of Jiamuhe Formation in Jinlong-2 Well Field

Abstract

The practice of volcanic reservoirs exploration and exploitation for years shows that fractures are not only important factors in controlling hydrocarbon migration and enrichment, but also favorable conditions for efficient exploitation. This study used drilling data, seismic data and laboratory analysis data to clarify fracture characteristics and distribution of volcanic reservoirs. in study area. The fracture characteristics were predicted by using post-stack structure-oriented coherence and ant tracking methods with the result of various fracture developmental degree of different zones on the plane. Comparative analysis of drilling data, geostress and imaging logging interpretation results have obtained preferable prediction results, which is of great significance for effective exploration and exploitation of volcanic reservoirs.
