| Abstract: | A new method of analyzing the productivity and calculating the recovery factor of low permeability reservoirs developed by elastic drive is proposed by taking account of the effects of threshold pressure gradient,pressure sensitivity and the decrease of fracture conductivity.The method has been validated by field data,allowing analysis and prediction of the productivity and recovery factor of low permeability reservoirs developed by elastic drive. |
| Keywords: | abnormal pressure low permeability reservoir threshold pressure gradient pressure sensitivity elastic development design |
