The present application provides a kind of new method for identifying oil well measure effect based on production index straight line analysis, which includes: step 1, screening the bottom hole flowing pressure and oil production rate monitored in single well oil well production;Step 2, the data screened in step 1 is analyzed and processed to obtain the production index of quantitative measure effect;Step 3, the production index obtained in step 2 and the corresponding time are plotted in double logarithmic coordinate system;Step 4, the graph plotted in step 3 is linearly fitted, and the physical meaning of the inflection point of the straight line is identified in combination with oilfield site information;Step 5, the critical production index is obtained by using the straight line fitted in step 4 to identify the measure effect and the measure effective time.The new method for identifying oil well measure effect based on production index straight line analysis can effectively identify the oil well measure effect, and has the advantages of simple and fast identification, high identification rate, and is easy to popularize and use.
