Application of multistage acid fracturing technology in deep carbonate thermal reservoirs

As the most common stimulation treatment in carbonate reservoirs, acid fracturing is also frequently used geothermal wells, but it has not been applied deep thermal reservoirs. The application of a multi-stage technology Xiong’an reservoir introduced this paper. field achieved good effect. Multistage can effectively communicate aquifer reservoir, improve length corrosion fracture, increase conductivity and water yield well. worthy to be popularized.
