- Abstract
The result becomes worse and worse with the increase of multicycle huff and puff. In order to stabilize the oilfield production in tight oil reservoirs, this study proposes a new development method which integrates CO2 huff and puff with factory fracturing technology. Based on the advanced seepage mechanics and reservoir engineering theory, this study considered the Non-Darcy flow and took one oil block named W for an example to raise 8 design projects. This paper chose the best one by numerical simulation software. The results prove that: (1) under the same reservoir conditions, the technique of CO2 huff and puff in multi-stage fractured horizontal wells (MSFHW) in tight reservoirs can complement the formation energy and improve recovery efficiency, this method also have an advantages over water or gas injection in the combination spacing of vertical and horizontal wells; (2) the effective integration of CO2 huff and puff with factory fracturing technology can not only improve exploitation effectiveness in high oil saturation bank on either side of old manual fissure, but also can complement the formation energy, so that recovery percentage can be increased by 3.79% over the single technology of CO2 huff and puff. The study can serve as a guideline for the secondary development in tight oil reservoirs.
