| Abstract: | The foam components mainly composed of AES are selected according to the tests of high-speed agitation and core flow,which show the good performance and low damage to core permeability.Have accomplished the field test of foam washing 17 wells following the results of indoor test.The field test results show that the stabilization and sand carrying capacity of foam are high.The subsequent washing process can clean the sand and gravel out of well end,which is higher effect compared with the method of air washing. |
