摘 要:泌浅10区IV9层属于浅薄层特稠油油藏,单井平均吞吐达到10周期以上,可采储量采出程度已达64%。吞吐后期注入水和边水水淹严重、平、剖面矛盾突出,生产效果变差,实施综合治理前油组产能只有10吨左右。通过剩余油监测资料分析和沉积微相研究,有针对性地实施了氮气助排、泡沫调剖、降粘、复合调剖、潜力油井扶产及低效井调层回采等措施,油组产能上升到80吨以上,取得了较好的治理效果。Lactating shallow 10 region IV9 layer belongs to superficial layers extra-heavy oil reservoir,the average throughput of one well has reached 10-week period above,and recovery degree of recoverable reserve is 64%.In the post throughput,the injecting water and edge water flooded severely,and contradictions between flat and profile is obvious,so the production effect is not good and the productivity of oil group is only about 10 tons.By monitoring data analysis of remaining oil and study of sedimentary microfacies,some countermeasures is made,such as,nitrogen gas cleanup,foam profile control,viscosity,complex profile,potential oil grab and adjusted mining of low effect well and so on,as a result the productivity of oil group is more than 80 tons,and better governance effect has been made.
