[Abstract]:The recoverable reserves of shale gas in China rank first in the world. However, the development of shale gas in China is faced with a series of difficult problems, such as complex conditions of gas reservoir occurrence, intense geological tectonic movement, extremely low permeability of reservoir, lack of water resources in rich gas reservoirs, etc. It is urgent to innovate the theory and method of shale reservoir reconstruction and to explore the unconventional theory and technology suitable for high efficiency development of shale gas in China. This paper briefly analyzes the main methods, principles, problems and challenges of reservoir fracturing at present, and puts forward the theory and technical conception of reservoir fracturing. The definition of mass fracture is a complete mechanical process, which is the interaction of internal pores, bedding fractures and artificial fissures, and the formation of a new three-dimensional fracture network system, which is a complete mechanical process of rock mass with large scale and multiple fissures. The process of high intensity destruction and energy release. It is pointed out that the three dimensional fracture morphology and propagation mechanism of shale, the interaction between artificial fracture and structural fracture, the shape and evolution of fracture net, and the load type of high body fracture can be realized. The new techniques of visualization and simulation of the real 3D fracture process, such as the mode and medium, are used to construct the research framework of the theory of bulk fracture mechanics. Based on the exploration of early laboratory and field experiments, this paper puts forward and analyzes the new technology of realizing volume rupture and the key scientific problems and technical difficulties to be studied.
