针对传统工艺技术提液不理想问题 ,大港油田作业二区在港西油田采用大排量螺杆泵新工艺技术提液 ,取得明显效果。其中西 8— 1 0井日增油 1 5t,西 43— 6— 2井日增油 6 t,西 5— 6井日增油 7t,含水均大幅下降 ,已有 3口油井超过原免休期 ,达到降低修井作业费用、提高采收率等 In view of the unsatisfactory extraction of traditional process technology, Dagang Oilfield Operation Zone 2 adopted the new process technology of large displacement screw pump in Hong Kong-West Oilfield to obtain significant results. Among them, the west 8-10 wells increased oil by 15t, the west 43-6-2 wells by 6t, the west 5-6 wells increased by 7t, the water content decreased sharply, and 3 oil wells had surpassed the original exemption Period, to reduce workover costs, improve oil recovery and so on
