Research and application of hydraulic fracturing technology in Yongbei glutenite reservoir

In view of the hydraulic fracturing difficulties in Yongbei glutenite reservoir,the research covering on reservoir protection,sand conglomerate rock mechanics characteristics,extension regularity of artificial fracture,high seam control and temporary plugging fluid was carried out and then a set of effective density glutenite reservoir hydraulic fracturing technology was formed.The technology was applied in 36 wells,with effectiveness rate of 94.4% and achieved remarkable fracturing effect.
