| Abstract: | In order to study the influence of perforation parameters(damage radius,perforation length,perforation density,perforation diameter and perforation extent) on the productivity of horizontal wells,this paper combines the skin factor model of perforating completion with the semi-analytical productivity prediction model of horizontal wells to calculate the skin factor and productivity of horizontal wells to different perforation parameters.Through calculating the perforation skin factor and productivity of horizontal wells to the different perforation parameters respectively and drawing the relationship charts between different perforation parameters and skin factor and productivity of horizontal wells,the influence of perforation parameters on skin factor and the productivity of horizontal wells are analyzed.The study results show that the perforation length should be greater than the halflength of damage zone in order to get more productivity.The phase angle should be optimized after the perforation length,perforation density and perforation diameter is ascertained.Perforation project is very important for partial perforating completion.If perforation project is selected very well,ideal productivity can be achieved even the perforation extent is small. |
