| Abstract: | A deflagration-acidification complex technology is used in injection well to increase the effective penetration depth of acidification liquid. The combination of the deflagration-fracturing effect and the acidification-eroding effect can eliminate channel jam caused by invaded mud, bacteria and other impurities in the perforated intervals during the well drilling and completing process so as to increase water injection rate. The operation method, usable range and field application of the technology are described. The injection stimulation effect of the technology experimented in Changqing and Henan oilfield is rather good. |
