Simulation of hydraulic fracturing of jointed rock
This paper presents a modeling approach for three-dimensional simulation of hydraulic fracturing of jointed rock. The base for a successful computer based simulation for productive use is the ability to calculate the fractured volume with sufficient accuracy and efficiency. Especially in cases three dimensional effects have to be taken into account, the common commercial software tools in oil a...
متن کاملTectonics, fracturing of rock, and erosion
[1] We argue that by fracturing rock, not by raising it relative to base level, tectonics plays its most important role in causing rapid incision of valleys and rapid erosion of hillslopes. Tectonic deformation riddles the upper crust with fractures, which not only provide avenues for water flow and thus promote weathering and further disintegration of rock but also fragment bedrock into debris...
متن کاملResearch on Chaos Characteristic of Crack Evolution in Coal-rock Fracturing
Precisely describing the formation and evolution rules of coal-rock fracturing crack have great value on reservoir fracturing improvement and highly efficient mining of coal bed methane well. In this paper, a non-linear dynamic method is used to study crack damage evolution behavior of coal-rock fracturing. Considering distribution characteristics of natural cracks in coal-rock, and based on da...
متن کاملHypervelocity Impact on Rock
Concerted research efforts are being made to find new means of rock disintegration for more rapid, efficient excavation. Water jets, metallic jets and hypervelocity projectiles have been found to cut or break rock with varying degrees of efficiency depending upon several parameters, which are being defined by research in Russia, Britain and the United States. Optimum performance of high velocit...
متن کاملRelating Topological and Electrical Properties of Fractured Porous Media: Insights into the Characterization of Rock Fracturing
Numerous laboratory and field experiments suggest that electrical properties of fractured rocks may provide critical information regarding the topological properties of the underlying fracture networks. However, a lack of numerical studies dedicated to realistic fractured media prevents us from assessing, in a systematic manner, the relationships between electrical and topological properties in...
