The Study Of Shale Gas Reservoir Characteristics And Adaptability Of Explosive Fracturing

Shale gas reservoir belongs to low porosity, low permeability reservoir, to get industrial production are generally in need of fracturing. Work in the area of shale gas development in foreign countries are more fully, the technology is more advanced, but shale gas development in China is still in the initial stage, the suitable fracturing mode of shale gas reservoirs of understanding and the research is still not enough, still need to do a lot of research.In this paper, the research of the domestic and foreign development status of shale gas, and analyzed the formation characteristics of shale gas reservoirs through test, summarizes the advantages and disadvantages of various reservoir reconstruction of shale gas reservoirs, analysis the adaptability to shale gas reservoirs, puts forward the hydraulic fracturing and nitrogen foam fracturing of these two kinds of cheap, little damage to formation and may obtain the hydraulic fracturing method widely used. And analysis the adaptability of explosive fracturing technology particularly which is a new type of reservoir reconstruction in mining shale gas.Study on explosive fracturing stimulation technology relates to the dynamics of explosion process very complicated problem, it is difficult to make exact analytical analysis, need the help of numerical simulation. In this paper, by using LS-DYNA finite element software, imitating a micro unit’s dynamic simulation response under explosion load based on the strata from different loading conditions of different explosive load and different properties of rock, describing the dynamic response of rock under explosion load, the conclusion can be provides the technical reference for explosive fracturing in the later experimental research and field application.
