Abstract

Abstract

Tight sandstone oil gas is an important unconventional resource.As the primary seepage channel, fracture networks commonly have the charactistics including complex distribution regularity as well as multiphase development and filling process, which directly influence fracture prediction accuracy.At present, there is no systematic method for solving the quantitative prediction of structural fissures, which is still in the exploration stage. Therefore, it is necessary to explore more about fraction networks identification, filling process and formation-superposition evolution mechanism. and set up a reasonable fracture characterization model for quantitative prediction of fracture networks parameter distribution range. On the basis of plenty of literature research, it is believed that the research of tight reservoir fracture is mainly in three key directions.Field observation and core observation were carried out to analyze the development characteristics of fracture networks.combing with tectonic evolution history and fluid-inclusion analysis, fractures development times were defined. Then, hydrothermal filling simulation experiments and rock mechanics experiments were conducted to reveal the mechanism of fractures filling and dynamic process of fractures from initiationto extension and superposition. Finally, experimental statistical methods were used to establish the anisotropic failure criterion in view of different filling rules and create quantitative characterization of fracture parameters based on the principle of conservation of energy and the theory of strain energy density factor. At last, a theoretical system of multiphase fractures development and their parameters characterization were formed and completed, which provides an important scientific basis for the exploration and exploit of tight sandstone gas field.
