Taking the Bohai Q oilfield as an example, this paper focused on how to improve the effect of liquid production increase in fluvial facies reservoir and counted the effects of measures to increase the production of oil wells in the oilfield in the past five years. The sensitivity of oil wells was analyzed from static and dynamic aspects,and the effects of liquid production increase measures on static and dynamic parameters were studied to analyze the effective timing and scale of increasing liquid production.According to the effect of the measures, classification schemes for the liquid production increase of water?drive reservoir in Bohai fluvial facies were established.The results show that if oil wells in the reservoir are in Class Ⅰ liquid production increase stage (20 000 mD ? m<formation coefficient ≤40 000 mD ? m,0<flow coefficient≤300 mD ? m/(mPa ? s）,25 000 m³<accumulated oil production before liquid production increase≤50 000 m³,0<accumulated liquid production before liquid production increase≤300 000 m³,65%≤water content before liquid production increase<80%),their daily oil production increment after liquid production increase will be possibly greater than 30.0 m³. The daily oil production increment of oil wells in Class Ⅱ liquid production increase stage is between 15.0 m³ and 30.0 m³,and that of oil wells in Class Ⅲ liquid production increase stage is less than 15.0 m³.The high?efficiency stimulation timetable was verified in the southern part of the Bohai Q oilfield.This is of great application value and can provide a basis for the efficient development of offshore fluvial water?drive reservoirs.
