| Putaohua oil field has been developed for many years, through adjustment of primary infilled well pattern and secondary infilled well pattern, the oil field has been entering production decline period at present, conflict between reserves and production becomes more and more obvious. Based on reasons mentioned above, in depth study on development position, production decline trend, potential, and overall balance coefficient must be done in Putaohua oil field; difficulties and advantage of the oil field, effect of potentiality measures, ability of controling production decline and ability of controling water cut of old well, ability of renewing output of new well should be known and mastered. Then reasonable development planning and disposing of the oil field can be obtained.Based on combining with factual development status of development zones, decline trend of development zones is studied in the paper; variation rule of development index is analysed, reasonable exploitation limit of main development index is certained. The reasonable exploitation limit of main development index is studied mainly, the results mentioned above can supply scientific gist for development and integrated adjustment of Putaohua oil field. |
