Shale gas reservoir fracturing proppant settlement

Shale gas reservoir fracturing proppant settlement regularity and the experimental research on shale gas development is a system, a vast amount of engineering, its high technical requirements and more money. Horizontal well development and technology of hydraulic fracturing is the core of the shale gas development. Than with conventional guanidine gum fracturing fluids, gliding water to form complex fracture network, greatly improve the effect of well stimulation. As a result, the shale gas reservoir fracturing slippery water often used as a fracturing fluid, large displacement, low viscosity construction method. Low viscosity, but due to slippery water carrying capacity is poor, proppant settlement regularity with different conventional petroleum proppant gum fracturing fluid. At present, China about shale gas reservoir, fracturing proppant settlement rule research focuses on the theoretical aspects, construction technology and main draw lessons from foreign practices, or software simulation based on the experience, lack of effective means of experiment; Especially for gliding water carrier proppant settlement, the migration regularity of research is still in its infancy, lack the necessary indoor experiment and system theory to guide the shale gas reservoir fracturing design and construction. To this end, the author designed a model device, and through the device simulation gliding water carrier in the fracture process, studies the construction capacity, seam width, proppant sand particle size and viscosity of fracturing fluid and than within the fracture parameters such as Hydraulic Fracturing Proppants settlement and the influence of the conveyance speed, so as to provide reference for establishing reasonable construction parameters.
