Aiming at the problems of separate -layer polymer injection by single hollow tube,such as big differences before and after testing,poor universality of testing charts,the testing process was optimized.According to the injection con-ditions,the viscosity of various polymer solutions and the offset of testing curves were analyzed and calculated to amend the testing charts.The field application results showed that after improving testing process,the testing success rate and the qualified rate of separate -layer were increased by 36% and 22%,respectively.Thus this can reduce effectively the cost and workload of testing,which is significant to the stable development of the polymer injection area.
