Abstract:Effect on fracture diverting capacity in proppant embed depth experiments, mainly on fracture closure stress of proppant embedded depth and the influence of proppant embed depth influence of the harm of diverting capacity etc detailed research. The study found that the proppant embed depth increases with the increase of closure pressure, but it does not follow the linear relationship, when closing pressure is greater than 25 mpa, embedded depth and pressure relationship is linear. Influenced by lithology of proppant embed, core young"s modulus, the greater the degree of its embedded is smaller. Single sanding concentration, the fracture diverting capacity is very obvious, along with the change of embedding depth of approximating linear change, sensitive to stress. This paper has also established proppant embed depth of fracture diverting capacity quantitative calculation model of shadow, support can be used to predict fracture diverting capacity, to field fracturing has certain guiding significance.
