贵州凤冈地区页岩气储层裂缝发育研究

In order to find out the main controlling factors for the development of shale gas reservoir in Fenggang area of Guizhou，this paper uses the imaging logging analysis method，Cambrian Niutitang Formation shale fracture characteristics and main controlling factors were studied. Research shows that：a period of time more intense tectonic movement made the fracture development in the area complex，and caused multiple fracture system mutual crisscross、cutting，resulting in the folding form which is given priority to with wide spaced syncline bodies；Standing in the perspective of Niutitang Formation shale core fracture characteristics，tectonic fracture is the main，horizontal、vertical cracks of the main body，part of the core broken seriously，and cracks in most other mineral composition；shale of brittle minerals accounts for the proportion to be high, Feldspar and quartz are main reservoir type . This tectonic movement is easy to create a natural fractures, which can effectively improve the production of shale gas.
