The North 32 District stone carbon reservoirs in Xinjiang oilfield well are low permeability, fine throats, volcanic reservoirs, of whose reservoir space are mainly pores and micro-cracks occurred in filling a calcite dissolution, and connection of every corrosion pore is poor, and the effect of conventional fracturing treatment measures as not 0bvious. Based on analyzing problems of reservoir space, physical properties, lithology and early fracturing treatment probleems in North, 32 Wells stone carbon reservoir, the acid fracturing treatment technology based on multi-stage injection of acid of pressure closed acidification technology, gelling acid systems and supporting optimization technology, field application achieves a significant effect of increasing yield, which provides a technical support for efficient development and production to the stone carbon-based reservoir of North32 area.
