摘要:

以渤海Q油田为例,针对渤海河流相油藏改善提液措施效果,统计Q油田近5年油井的提液措施效果。从静态、动态两方面分析油井提液的敏感性,总结油井提液措施效果在动态参数及静态参数上的变化规律,分析切实有效的提液时机与提液规模。结合油井措施效果,建立渤海河流相水驱油藏油井提液挖潜分类表。研究结果表明,渤海河流相油藏处于Ⅰ类提液阶段(2.0万mD?m<地层系数≤4.0万mD?m、0<流动系数≤300 mD?m/(mPa?s)、2.5万m3<提液前累计产油量≤5.0万m3、0<提液前累计产液量≤30万m3、65%≤提液前含水率<80%)的油井,提液后日增油量大于30.0 m3;处于Ⅱ类提液阶段的油井,提液后日增油量在15.0~30.0 m3;处于Ⅲ类提液阶段的油井,提液后日增油量小于15.0 m3。该提液高效挖潜时机表在渤海Q油田南区得到了验证,具有很好的实际应用参考价值,可为海上河流相水驱油藏高效开发提供依据。

Abstract:

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.
