海上L油田低产低效井综合治理研究与实践

Research and Practice on Comprehensive Treatment of Low Production and Low Efficiency Wels in Offshore L Oilfield

随着油田开发时间的延长和采出程度的提高,开发矛盾日益突出,低产低效井所占比例较高,严重制约了L油田的高效开发。针对L油田的实际情况,结合经济极限产能与开发经验,定义了低产低效井,分析了不同类型的低产低效井成因。通过精细地质油藏研究,结合采油工艺新技术,制定了相应的治理措施,已治理的低产低效井取得良好效果。

With the prolongation of oilfield development time and the improvement of recovery degree,the contradiction of development is becoming more and more prominent. The proportion of low production and low efficiency wells is relatively high,which seriously restricts the efficient development of L oilfield. In view of the actual situation of L oilfield,combined with the economic limit productivity and development experience,The definition of low production and low efficiency wells is given, and the causes of different types of low production and low efficiency wells are analyzed. Through fine geological reservoir research, combined with new technology of oil production technology,the corresponding control measures are formulated,and the low production and low efficiency wells that have been treated have achieved good results.
